Lung cancer is the degeneration of epithelial cells of the bronchi or lungs into various types of malignant tumors. According to the place of occurrence, such neoplasms are usually divided into: central, peripheral or mixed (massive type). Any type of cancer is characterized by rapid cell division with tumor growth, and the spread of pathologically altered tissues by the flow of blood or lymph, which leads to metastasis.

In men, the tendency to this disease is observed much more often than in women. It is noteworthy that in the countries of South and especially Central America, cancer is practically not found (which some experts associate with the love of the inhabitants of these countries for a drink made from prickly pear cactus).

Unlike the international TNM classification, a slightly different one has been adopted in Russia, including 4 stages of lung cancer:

	Stage I - tumor size up to 3 cm at maximum, no metastases.
	Stage II - tumor size up to 6 cm, the presence of individual regional metastases in the area of ​​the lymph nodes.
	Stage III - a tumor larger than 6 cm spreads to neighboring segments of the lung or bronchi with metastases in the lymph nodes.
	IV stage - the germination of the tumor beyond the boundaries of the lung, the appearance - in addition to local - distant metastases.

Symptoms of lung cancer

The primary symptoms of lung cancer may be a cough that worsens over time, later the appearance of bloody sputum, shortness of breath, weight loss, general weakness, often chest pains, frequent bronchitis and pneumonia. Unfortunately, it is extremely difficult to recognize the onset of the disease at the earliest stages. Especially in peripheral rather than central cancer, since the absence of nerve endings in the lungs does not give signals about the appearance of a tumor - up to the period of growth of metastases beyond its borders and transition to other organs.

Diagnosis of the presence of cancer in the lungs

The simplest and most affordable means of early diagnosis is regular preventive examinations, including x-rays. Unfortunately, this practice is typical only for public and individual private institutions - and officially non-working citizens independently seek help, as a rule, only in the later stages of the spread of the disease, which greatly complicates its treatment.

If radiography was performed, the diagnosis will be clarified by endoscopic bronchography. With its help, it will be possible to get an idea of ​​the size and composition of the tumor, as well as to take a piece of the affected tissue for cytological examination (biopsy). In recent years, thoracentesis, mediastinoscopy, MRI, CT and radioisotope scanning have also been added to these proven diagnostic methods.

Treatment Methods

At the present level of development of medicine for the treatment of lung cancer, a complex application of 3 methods is used:

Oxygen concentrators in the treatment of lung cancer

One of the modern devices that can significantly alleviate the condition of patients with lung cancer are oxygen concentrators. This is due to the hypoxemia developing in patients in the late stages of cancer, which sharply reduces the amount of oxygen in the blood and leads to a painful feeling of shortness of breath. The use of these devices (all the best models of which provide the necessary minimum of 5 l / min of a concentrated 95% oxygen mixture) not only reduces pain, but also improves blood quality.

Lung cancer: symptoms, diagnosis, stages and improvement of the patient's well-being with oxygen

Lung cancer is a malignant neoplasm that develops from the glands of the bronchi, mucous membranes and lung tissue. This disease is one of the most common causes of death. Timely appeal for help can avoid a fatal outcome. The main provoking factor in the occurrence of the disease is considered to be smoking. Specialists distinguish two types of lung cancer: peripheral and central. The first develops in the lung tissue, and the second - in the bronchus.

To begin the fight against a tumor, it is necessary to determine the morphological type of the disease (non-small cell or small cell) using a biopsy. This examination makes it possible to remove tissues or cells and analyze part of the tumor using a microscope. It is very important to undergo a biopsy, since different morphological types of the disease require different treatment. Most often, patients suffer from non-small cell lung cancer, characterized by slow growth of tumors. This type usually includes: adenocarcinoma, squamous cell carcinoma, large cell and mixed cancer. Small cell lung cancer is considered very dangerous, which is accompanied by the rapid spread of the tumor. This type is characterized by the early occurrence of metastases, the rapid growth of the neoplasm. To avoid the negative consequences of lung cancer, you should pay attention to certain signs of the onset of the disease in a timely manner.

Lung cancer: symptoms of the disease

Today, all doctors agree that the sooner the symptoms of lung cancer are detected, the sooner it will be possible to diagnose the tumor and begin its treatment.

Signs of the development of such a dangerous disease can be considered:

• Labored breathing;
• Wheezing in the chest;
• Cough;
• Hoarseness of voice;
• Sputum with blood;
• Significant weight loss;
• Loss of appetite;
• Pain in the chest (stabbing, pressing, sharp, dull characters);
• Increase in body temperature;
• Persistent headache;
• Swelling of the face, neck, hands.

The earliest signs of tumor development are considered to be a strong prolonged cough and blood in the sputum, shortness of breath and chest pain. When the neoplasm is in the upper parts of the lungs, there are discomfort in the neck, weakness in the muscles of the arm, blurred vision, drooping of the eyelid. If the patient has found the listed signs of the disease, you should immediately seek help from a doctor. Despite the fact that such symptoms may be manifestations of less dangerous ailments, you should undergo an examination. Lung cancer often occurs in a latent form, especially if the tumor is small (peripheral type). However, in rare cases, for example, when a neoplasm appears in the bronchus, symptoms appear early. Modern diagnostic methods allow you to quickly identify the disease.

Diagnosis of lung cancer: modern methods

As a rule, the first study that is prescribed for suspected lung cancer is a chest x-ray. When the examination showed the presence of a formation similar to a tumor, it is necessary to turn to additional diagnostic methods. In order to confirm or refute the diagnosis, it is recommended to perform computed tomography of the chest organs. This study begins with the patient lying down on a special table, which is directed inside a machine that scans the lungs with x-rays.

During the examination, the person does not experience a feeling of discomfort. The entire procedure takes approximately two to three minutes. A couple of hours or days later, the patient receives pictures and a medical report on the condition of the chest. After an x-ray, the doctor, based on the results of the examination, concludes whether there is a neoplasm or not. In certain cases, it is required to undergo a bronchoscopy, which is accompanied by the introduction of special medical equipment through the nose. This diagnostic method is necessary in order to examine the airways. If a tumor is found as a result of examinations, the specialist performs a biopsy (removal of tissue or cells from the body). This procedure is carried out using the appropriate devices. For example, in peripheral lung cancer, a needle is used to help pierce the chest and take cells. It is advisable to undergo all the necessary examinations as early as possible, as this increases the chances of getting rid of the disease. In addition, the diagnosis shows at what stage the disease is.

Lung cancer: stages of the disease

The course of lung cancer is divided into certain stages in order to understand what treatments are required in a particular case.

In the non-small cell type of the disease, four stages are distinguished:

• The first stage (a small tumor located in the right or left lung does not penetrate beyond the lymph nodes or into other organs);
• The second stage (the neoplasm can be of different sizes, grows into the lymph nodes of the lung);
• The third stage (a large tumor that grows into lymph nodes located in the tissues between the lungs).
• The fourth stage (the formation of a huge amount of fluid around the lung or the presence of a neoplasm in the lymph nodes or tissues of the opposite lung).

The fourth stage is the most dangerous, since it is usually accompanied by the appearance of metastases (foci of the pathological process in other organs).

As for small cell lung cancer, then with this type there are two stages:

• Localized tumor process (the neoplasm is located in the right or left side of the chest);
• A common tumor process (the tumor is actively distributed in different parts of the chest, metastases appear).

To avoid an increase in the tumor, you should start fighting it as soon as possible. Only if this condition is met will a person avoid death.

Lung cancer: ways to deal with the disease

The choice of method for eliminating lung cancer usually depends on the stage of the disease, the age of the patient, and the presence of chronic ailments. It is necessary to consult only with highly qualified specialists who are advised to turn to official ways to get rid of the problem. Traditional methods of treatment have not been fully explored, therefore, by engaging in alternative medicine, a person loses time that could be devoted to methods of treatment that have proven themselves on the positive side.

At the moment, chemotherapy and radiation therapy are used to combat small cell tumors. With a widespread tumor process, chemotherapy is prescribed. Sometimes the head is irradiated (to prevent the occurrence of metastases in the brain). With a localized process, treatment is required, both chemotherapy and radiation therapy. As for the non-small cell type, in this case, the main method is surgical intervention, due to which the airway patency is restored when using stents, the fluid around the lungs is removed.

Sometimes, after an operation, doctors determine that a person who was diagnosed with a second stage of the disease during the research process, in fact, has a third stage of lung cancer. In this case, additional treatment will be required. Basically, operations are performed at the first or second stages of the non-small cell type of the disease. The specialist removes part of the lung or one lung in case of a significant increase in the tumor. Some patients may also be recommended radiation therapy, during which ionizing radiation has a devastating effect on the tumor. As a result, the affected areas of the chest are exposed to radiation. The use of potent drugs that kill the tumor may also be prescribed.

In the third stage, for an effective cure, both chemotherapy, radiation therapy, and surgical treatment are used. After getting rid of the disease, you should be observed by a specialist after a certain amount of time. Thus, it becomes possible to identify the disease at an early stage in case of relapse. In order not to provoke the re-development of lung cancer, it is worth stopping smoking. Research results show that patients who did not give up the bad habit after treatment developed the disease again.

Despite the achievements of modern medicine, there are no effective means to combat lung cancer in the fourth stage or with a widespread tumor process. However, there are methods that can significantly improve the quality of life of the patient. For example, sometimes targeted treatments are used, which involve the use of drugs that affect only a certain type of cell. Oxygen therapy is one of the most well-known ways to relieve breathing problems and discomfort from lung cancer.

Lung Cancer: An Opportunity to Feel Better with Oxygen

Given that the course of lung cancer is accompanied by extremely unpleasant sensations in the chest, asthma attacks, it is necessary to resort to oxygen therapy. Carrying out this procedure is advisable, since with this dangerous disease, the volume of lung tissue is significantly reduced, resulting in hypoxia. The appearance of the latter means that the body needs oxygen and other nutrients. Thus, the functioning of the respiratory organs should be normalized, and oxygen therapy can help in this. It is carried out using a special concentrator.

It is difficult to overestimate the benefits of oxygen treatment, as it has a beneficial effect on the body, namely:

• Reduces shortness of breath;
• Improves the quality of sleep;
• Increases physical activity;
• Improves mood;
• Relieves stress.

The dosage of oxygen and the duration of the procedures is always determined by a specialist. Consultation with a doctor makes it possible to choose an individual therapy regimen.

(long title)" by Bubnovsky. there is a rationale for the usefulness of visiting saunas by cancer patients. and for everyone else - a sea of ​​\u200b\u200binformation on health promotion and rejuvenation

Now there is a device called an ozonator. Maybe someone heard. We ozonize water and drink. We ozonize products. Water saturated with oxygen. The principle of operation of the ozonator uses the natural mechanism for producing ozone after a lightning discharge. Ozonated water has a bactericidal, antiviral and antifungal effect. An ozonator can process food (meat, fruits, etc.) and will pull out all nitrates, chemicals, etc. from them. e. We eat a chicken leg, but it is crammed with everything, and when we ozonize it, so much mucus comes out of it that burns. As you guessed, these are chemicals for rapid growth, etc. That's where a bunch of diseases that can't be treated now come from, where doctors are at a loss, what's wrong with this patient? and endless trips to all clinics, professors begin. you can also ozonize the air, eliminates unpleasant odors, even mold. Ozonated water is recommended to drink for everyone with all diseases. Patients with skin diseases need to wash, bathe. Call anyone who is interested.

Oxygen in cancer is the cart before the horse. Compensation of hypoxia - oxygen starvation and organs of tissue cells due to respiratory failure, as a result of tumor growth and overlapping of the lumen of the bronchi themselves and pleurisy, which means insufficient opening of the lungs, is not a treatment. This is just an aggravation of the condition of a cancer patient as a whole due to literally a sip of oxygen making the breath relatively full, and therefore supporting gas exchange in the lungs only for minutes. And then oxygen again. But we need a completely different approach, and the sooner the better. in detail when contacting. Oxygen is only an aggravating factor, but in the case of palliative treatment, it seems to prolong the agony of the body of a cancer patient

With advanced lung cancer, the volume of lung tissue and the ability of the lungs to extract oxygen from the air are reduced. Hypoxemia occurs (decrease in the concentration of oxygen in the blood). In the case of hypoxemia, oxygen therapy with an oxygen concentrator is an important way to reduce shortness of breath and improve quality of life.
It has been proven in scientific studies that in advanced lung cancer, in patients with hypoxemia (low oxygen in the blood), oxygen treatment can reduce the painful feeling of shortness of breath. The required oxygen dose (flow) is typically around 5 l/min.

There used to be oxygen bags in pharmacies, then there were oxygen inhalers with oxygen bottles that had to be refilled and oxygen bottles in pharmacies. Now there are oxygen concentrators that get oxygen from the air at home in the hospital - all you need is electricity. True, they are noisy when working. A tube is attached, the mask the patient breathes if there is not enough oxygen. .
I won’t say how much they cost, you can take the smallest one, probably enough for the patient ... Some organizations offer medical equipment for rent and oxygen concentrators....

I can not breathe

Margarita Tulup, journalist

For the first few minutes, Zhenya could not believe what was happening: he was sitting on the bed, breathing quickly and often, but his lungs were not filling with air. Then the panic began. His wife held his hand, and she called an ambulance. Ten minutes before her arrival seemed like an eternity, the forces became less and less. Zhenya made several unsuccessful attempts: he sat down, pressing his knees to his chest, raised his hands up in the hope of expanding the diaphragm, breathed like a dog, but he could only swallow air like a fish and repeat to himself: “This is the end. May it come sooner." Most of all, Zhenya wanted to say goodbye to his wife, but he could not utter a word.

There was no oxygen equipment in the first ambulance, so we had to wait for the second one. Paramedics from the second brigade put a mask connected to an oxygen cylinder on the almost unconscious Zhenya, put him on a chair in a car and took him to the Institute of Emergency Surgery. It was winter. He had to sit in shorts and a jacket in the ambulance for about an hour. Zhenya has tuberculosis, his left lung is constricted, in his right there is a hole the size of a fist. This means that only a few hospitals can accept it.

In one of them Zhenya was disconnected from the ambulance's oxygen tank, put on a gurney and taken to the ward. There was nothing to breathe again, the agony began. Zhenya began to cry and demand oxygen. The doctors condescended - they brought one blue balloon with a thin, as if from a dropper, tube for one nostril, but its power was not enough. I had to endure. For the next three days, Zhenya was recovering from the operation, breathing with the help of oxygen brought into the ward, which was supplied through tubes coming out of the wall.

Three days later, he was transferred to the surgical department of the regional TB dispensary, where he again had nothing to breathe. Next to him, on iron cots, people were dying from lack of oxygen. Several young girls who fell ill immediately after giving birth, a lonely guy, grandfather. None of the staff visited the patients.

Only once did the doctor respond to a request for help - he looked into the ward and said to the young guy: “Yes, you are suffocating. What can I do? You don't have lungs."

Four days later the patient got up, took a cup of water, sighed, poured it over himself and fell down. His agony ended forever.

Oxygen support from year to year is needed by patients of completely different age and condition. Most often, it is needed by those whose blood oxygen saturation is too low, the respiratory muscles are atrophied: patients with tuberculosis, cancer patients with lung metastases, neurological patients, people with amyotrophic lateral sclerosis, spinal muscular atrophy, who have been in an accident, children with a rare disease cystic fibrosis. All of them, in order to fully breathe, and therefore live, need the help of special devices.

Often they become hostages of resuscitation because they are literally tied to oxygen. Getting out of intensive care means for them to stop breathing. Those who can live without a device or have collected money (by themselves or with the help of philanthropists) to buy it go home.

There is no state funding separately for oxygen support for patients, and therefore if special devices are bought, then more often for intensive care units or pulmonology departments, carving out a piece from the regional budget for health care. But this is also rare.

Most often, hospital staff either do not see the need for oxygen, or are afraid to notice it. Therefore, at best, Soviet oxygen stations operate in some departments - tubes come out of the wall; and in the majority - the staff uses a cylinder or an oxygen pillow - a rubberized mattress, which is filled with oxygen from a cylinder. In this case, the patient needs to lie down, hug her with his hands, take a mouthpiece into his mouth, on which wet gauze is put on (“dry” oxygen can lead to lung burns and death) and breathe until you “exhale” its contents.

According to palliative care physician Zoya Maksimova, the issue of oxygen should not only be about state funding, but also about the education of medical staff.

At trainings for doctors, I always find that doctors simply do not know about the existence of oxygen concentrators. In therapy, even an oxygen bag is a rare thing. They "dripped" a person, treated him and sent him home. He is not recommended to breathe oxygen because he simply will not find it anywhere. And now the person returns home, suffocates, calls an ambulance (in which there are no cylinders either, or they don’t know about them). So a person either remains at home to die, or ends up in intensive care for a long time and takes a place there.

Second wind

The wife was lucky to survive and learn to breathe with the rest of her lungs. He began to consider buying an oxygen tank for home. To begin with, it was necessary to save up about four thousand hryvnias for it, then bring the 100-kilogram device home, lift it to the apartment, and then monitor its safety (cylinders explode even in hospitals, let alone apartments). Periodically, the device would have to be taken out and taken with it to the edge of the city in order to fill it with a new portion of oxygen.

At the same time, Zhenya learned that in Europe unsafe cylinders had long been abandoned in favor of stationary oxygen concentrators - small boxes that turn atmospheric air into pure oxygen and supply it through tubes to both nostrils or through a mask. Such devices do not need to be refueled, only filters need to be changed from time to time.

Even later, he learned that these concentrators are also portable - a small bag for overweight, which gives complete freedom. With it, you can stop being a hostage to the walls, go for a walk, go on business. You can live with her.

Zhenya found out that only one foundation in Ukraine deals primarily with oxygen support for patients - Kiev's Open Palms. The man collected the necessary documents, and the fund sent him an oxygen concentrator for free temporary use. Since then Zhenya has been able to breathe normally, be active and go outside.

Meanwhile, as he runs around on business, he suffocates, and at home he breathes calmly under the apparatus, Zhenya manages to live in such a way “that it would be easier for others”. He helps people with tuberculosis like himself: he buys them small things (toilet paper, razors or sweets), advises on the restoration of documents, and simply supports them by phone.

Two years later, Zhenya found out that the dispensary where he was denied oxygen had cylinders and pillows on the balance sheet, and decided to ask the doctor why they were not being given to patients. “Yes, we have a balloon. Suppose we would give it, a person would live not 10 hours, but 24. But he will still die. And we need to write in the medical card, fill out various papers, fill the cylinder with new oxygen, ”the doctor answered.

Then Zhenya told the staff that there were easy-to-use oxygen concentrators, and advised them to take them from a charitable foundation, having agreed on this by phone. “Good idea,” the doctors replied. But they did not call the fund.

From time to time Zhenya receives calls from patients who find it difficult to breathe. They ask for help, but the man doesn't know what to do. “If those who are suffocating wrote an official statement about the lack of assistance, we would be able to influence the situation. But those who need oxygen are not at all up to it, they would have to take an extra breath, ”says Zhenya.

The last time an unknown number called him was at eleven o'clock in the evening: the young guy was crying and choking. Zhenya and his wife Oksana loaded their concentrator into a car and drove to his dispensary. The guy died a couple of days later.

And if at this time you needed the device? - I ask Zhenya.

Did I have any way out? he shrugs.

One summer, 14-year-old Anya went to a store near her home. She did not have the strength to go back: she could not breathe, she stood in the middle of the street and cried. Since then, Anya can no longer breathe normally: a congenital disease manifested itself after the flu and developed into pulmonary fibrosis. Today she is 29, her illness is progressing. Her chance for salvation is a lung transplant in India at the expense of the state. She believes that her turn will come, but waiting for this moment without oxygen support is becoming increasingly difficult.

I don't even remember what it's like to breathe normally. I remember that before, like all children, I could run in the rain, ride a bike, play snowballs. But how it is - to breathe in the air with a full breast and not think about it, I don’t remember. Now I breathe with what is left of my lungs and elementary things are difficult. Sometimes I just can’t get out of bed because I start to choke, - the girl says in a hoarse voice, clearing her throat.

Anya was able to finish school, then a medical university. Every day until three in the afternoon she works as a medical examiner. Staying at work is dangerous for her: lack of oxygen will lead to shortness of breath, nausea, dizziness and loss of consciousness. Every day at four, Anya opens the door of her apartment and goes to bed motionless for several hours so as not to faint.

The cost of a portable oxygen concentrator for the fund is 100-120 thousand UAH.

I go to work because this is the last thread for me. It is so important for me to know that I am just like everyone else. It's a crime to lie in bed when you're 29!

Sometimes Anya "goes for 2-3 hours to breathe" in the hospital. Doctors have never denied her medical oxygen, but they cannot give her a device home. You have to wait in line or share it with other hospital patients - there is less oxygen here than those who need it. It often happens that the power of the apparatus for Anya is too low, which means that the effect of inhalation is rather sedative - for a short time you can relax a little.

Most of all, Anya is afraid that the moment will come when she will not be able to breathe: “It always seems to me that I am dying. Then it’s hard to cling to life,” she sighs, “But so far I’ve been lucky.”

All of Anya's savings and salary go to medicines and inhalers, and therefore she simply does not have the money to buy an oxygen machine. You have to live in constant fear. Anya dreams of breathing in oxygen at least once, and regrets that this is impossible: "I feel like a person while I breathe with the help of the apparatus. After that, life returns to normal."

Way to help

To date, the Open Palms Foundation has purchased and issued for temporary free use about 200 stationary oxygen concentrators, some of them have been transferred and put on the balance sheet of hospitals in Ukraine. Each such device for the fund costs 10-20 thousand hryvnias, and a portable one with batteries costs up to 120 thousand, but only a few of them were bought.

It is difficult to say how many devices are needed by patients in Ukraine now, because no one has calculated this need. The Foundation also never knows how many concentrators it will need, and what need it will be able to cover. One thing is for sure: there is never enough oxygen.

According to the foundation’s volunteer Marina Lobodina, no one takes responsibility for declaring the need for oxygen support: “Hospital doctors, if they admit that they need help, at best they say: “We would like a couple of devices.” Often, none of the medical staff wants to take responsibility for such expensive equipment, which means that the hospital does not want to take concentrators on its balance sheet. In addition, there is no mechanism for issuing hospital equipment free of charge for temporary use to patients at home.”

Both the Ministry of Health and the Kiev Regional Department of Health, in response to a request from LB. ua admit: no money was allocated for oxygen supply either last year or this year. Volunteers have never asked the state for funding for this need, they know that it is useless to hope for success in this matter in the near future. Because now they are asking for the support of society. They compete in the “Participation Budget”, a project that allows each of us to choose for ourselves, through online voting, what part of the local budget will go to.

The Foundation proposes to purchase and donate 30 oxygen devices of various capacities to Kiev. This will allow patients of the National Institute of Pulmonology, the hospice at the second clinical hospital in Kiev and the Center for Palliative Care for Children to breathe.

Last year, the fund's initiative turned out to be useless.

It's scary to believe that this could happen again.

Simply increasing the amount of oxygen in the air activates the cells of the immune system that kill cancer cells, and thus inhibits tumor growth. This is evidenced by the results of a study by scientists from Northwestern University in Boston (USA) led by Michael Sitkovsky and Stephen Hatfield, published in the latest issue of the journal Science Translational Medicine.

The principle is very simple. The resulting cancer grows so rapidly in size that the circulatory system can not cope with the supply of oxygen to the tissue in which they originated. In response to the low oxygen supply, tumor cells begin to produce the chemical adenosine, which suppresses the activity of immune system cells - T-cells, which are just supposed to fight cancer cells. As a result, they do not cope with their "duties", and the tumor continues to grow.

Researchers from different countries have long been trying to learn how to block the synthesis of adenosine. However, scientists from Northwestern University took a different path and tried to increase the concentration of oxygen, which gave excellent results.

In the experiment, the oxygen concentration in the air was increased from 21% to 60%. In such an atmosphere, up to 40% of laboratory mice with cancer lived for 60 days or more, while under normal conditions they managed to stretch a maximum of 30 days. In the figurative expression of scientists, oxygen "releases the brake pedal", which cancer cells "press" in front of the cells of the immune system.

"If it works, there's a possibility that what they [the scientists at Northwestern University] came up with will work well with other immunotherapies that have been proven effective," said Susanna Greer of the American Cancer Society. "The beauty is that oxygen itself is well tolerated," added Dr. Holger Eltzschig, an anesthesiologist at the University of Colorado Denver.

True, in large quantities, oxygen, as a strong oxidizing agent, is also harmful, so you still have to use the new method with caution.

* increase in quantity hemoglobin and keep it high
* regular exercise outdoors, especially walking, running, swimming
* special breathing exercises
* consumption plant food facilitating the penetration of oxygen throughout the body
