I don't feel uncomfortable, why do I have lung cancer?

When mentioning lung cancer, does the first reaction feel that its occurrence is related to smoking?

As the highest incidence and mortality cancer in my country, hundreds of thousands of families are shrouded in the shadow of lung cancer every year. Not only is it difficult to treat and spend high, but also the age of patients is gradually becoming younger.

The lungs are the most important organs in the human respiratory system. The oxygen in the air is absorbed by the human body through the lungs, thereby maintaining the normal function of the body. Therefore, the problem of the lungs is generally caused by the patient's inhalation of "unclean" gas for a long time, such as smoking.

Is it that you will not suffer from lung cancer as long as you don't smoke? The answer is not necessarily.

There are many causes of lung cancer, 80% of smoking, and 20% of people who do not smoke will also suffer from lung cancer.

Why is this? What factors can induce lung cancer?

01

What are the factors that cause lung cancer

1. Smoking

The probability of smokers suffering from lung cancer is more than 10 times higher than ordinary people. Second -hand smoke and three -handed smoke can cause irreversible damage to the respiratory system.

Clinically, the daily smoking average (branch) and smoking time (year) accumulation indicates the degree of previous smoking. Studies have found that the longer the smoking time, the more daily smoking (branch), the higher the risk of cancer.

2. Working environment

For work needs, employees in different industries are in different types of exposure risks. If the protection measures are not in place, the risk of cancer will also increase significantly.

For example, the main ingredient of building materials, asbestos, is not harmless to the human body, but because of the small fiber structure, it is deposited in the lungs after inhaling the human body.

3.

The ghost is more unfamiliar with most people. It is formed by the decline of radioactive elements in nature in nature. It itself is colorless and tasteless. The release of rays and radioactives when further decay. One of the factors of indoor air pollution.

These isotopes are inhaled into the respiratory tract in the form of metal particles, and the deposition of "internal radiation sources" is deployed, which causes damage to normal tissue cells in the lungs.

4. History of lung radiation therapy

Due to other cancer patients with a history of radiation in the treatment of chest, the risk of lung cancer is high.

5. Air pollution

Studies have found that outdoor air pollution has become the second largest high -risk factor in lung cancer after smoking.

Air pollution mainly comes from transportation, indoor cooking and fuel burning. The small particulate matter and coal combustion products in air pollutants are the highest, followed by the products of biofuel burning.

6. Family History

If there is a history of lung cancer in the direct family, especially more than one family member has a history of tumor disease, and when he is young, he should attract high attention.

Early manifestations of lung cancer

1. Cough

Patients with lung cancer can have 2 to 3 weeks of cough early in the early stage, and the effect of cough drugs is not effective after treatment. If you have blood in sputum, it is often a high -risk signal, which should attract high attention and go to the hospital for further examination as soon as possible.

2. chest pain

Some patients with lung cancer may have abnormal expression of chest pain when coughing. This is due to the continuous growth of tumor tissues and invasion of pleura, nerves or skeletal muscles. At this time, intermittent and persistent pain may occur on the chest, back, and shoulders.

3. Continuous low fever

In the human body with lung cancer, because of the "infinite growth" of tumor cells, inflammatory reactions appear in the whole body, or necrosis and infection with tumor tissues. Long -term or intermittent fever can occur. Anti -fever and anti -inflammatory drugs can be used. The effect is also poor. At this time, you should also go to the hospital for further examination.

4. Hoe with sound

Hoe hoarseness is another symptom of early lung cancer. If the growth of the lung cancer is close to the throat, the nerves of the controlled vocal cords are easily invaded, and the sound of gradually worsening at this time. In daily life, throat or throat surgery may also have hoarseness, but the hoarseness caused by lung cancer will not only improve the symptoms after treatment, but will increase.

5. Short chest tightness and shortness of breath

When the mass is compressed or blocked by the trachea and bronchies, the symptoms of chest tightness and shortness of breath are obvious, and they cannot be relieved even if they rest. In addition, lung cancer often affects the pleural effusion of the thorax, and gradually aggravates breathing difficulties.

For many people, the early symptoms of lung cancer are more difficult to attract everyone's attention. It is often mistaken for the discomfort of the body that has been tired and stressed recently, and it is difficult to associate them with lung cancer.

Therefore, after understanding the early symptoms of these lung cancer, we also need to know how to prevent lung cancer.

How to prevent lung cancer

1. Regular physical examination

Regular medical examinations can be found in time to detect lung problems and kill lung cancer in the cradle. In particular, the following three types of high -risk groups should pay more attention to the health of the lungs.

Men with a history of smoking over 45 years of age smoke are greater than 400 every year;

Those who have been exposed to carcinogens for a long time, such as people working at asbestos;

There is a family history of lung cancer in direct relatives; there is a history of extra -lung tumor; there are chronic lung diseases, including those who have cured lung tuberculosis.

2. Keep a good habit of living

Do not smoke, do not drink, maintain a good attitude, and can prevent the occurrence of lung cancer.Quit smoking is particularly important, and it is not advocated that in order to quit smoking to change electronic cigarettes, quitting smoking is to quit smoking, and there is no need to replace.Author ｜ Zhang Yingqi Hebei Medical University First Hospital, chief physician
