Lung cancer is mostly 'drag' out? Doctor: If you have '2 pains and 1 bulge' on your body, it is recommended to check

Many people think that cancer is far from our lives. In fact, diet, sleep, climate, soil and other factors may give you cancer. According to the latest cancer data report in China, there are more than 4 million new cancers and 2.5 million deaths in China every year, more than half of which are shocking.

If there is a cancer that wins in numbers and can be called the king of cancer, it must be "lung cancer"!

For many years, lung cancer has been the most common cancer in the world. Although its incidence was beaten by breast cancer in 2020, it still ranks first in mortality.

And in terms of the current status of cancer in China, the number of lung cancer patients and deaths is the largest, with more than 800,000 new lung cancer patients every year!

There are many causes of lung cancer. The smoking posture is dominant. Most lung cancers are found at an advanced stage. More doctors are outspoken that if lung cancer is caught early, it still has a good chance of being cured. It can be seen that most lung cancers are dragged out.

01

Why is lung cancer advanced?

1. Don't pay attention, don't care

Lung cancer generally has no obvious symptoms in the early stages. In the middle and late stage, cough began to appear. Chest pain. Mainly non-specific symptoms such as chest tightness.

If patients don't pay attention to their body's red flags and don't care about the associated disease risks, they won't go to the hospital. They are basically late when symptoms appear.

2. Overshadowed by the disease symptoms of the disease

Lung disease is a risk factor for lung cancer such as chronic obstructive pulmonary disease. Tuberculosis. Few people may be concerned about this, and people with lung disease have a history of smoking. During recovery, chronic inflammation in the lungs is prone to malignant transformation into tumors.

What is the cause of lung cancer?

1. Lung cancer

According to a large number of survey data in various countries, the etiology of lung cancer is closely related to smoking, and the increase in the incidence of lung cancer is parallel to the increase in cigarette sales.

Cigarettes contain a variety of carcinogens, such as benzopyrene, and inhalation of cigarettes or tar can induce respiratory and skin cancers in laboratory animals.

The incidence of lung cancer in smokers is 10 times higher than that of non-smokers, and the incidence of lung cancer is 20 times higher in smokers than non-smokers.

2. Ionizing radiation

The lungs are very sensitive to ionizing radiation. According to reports in the United States, the majority of cancers from radioactive mines in Ohio are bronchial small cell carcinomas.

Also, the United States dropped an atomic bomb on Hiroshima during World War II. A few years later, the number of lung cancer patients from local survivors exploded. The above two situations can prove the effect of ionizing radiation on lung cancer.

3. Genetics

It has to be said that the human body's genes are a wonderful existence, and everyone carries genetic information from their parents.

This genetic information can accurately distinguish people's characteristics, and lung cancer has a certain genetic susceptibility, coupled with the acquired environment, such people have a higher risk of developing lung cancer.

Especially among immediate family members, there are people diagnosed with lung cancer early, and the risk will be higher for family members!

4. Air pollution

For example, indoor environmental pollution and outdoor environmental pollution. Indoor pollution usually includes smoking. Fuel. Fume from cooking can also lead to the production of carcinogens.

Outdoor air pollution includes industrial waste gas, asphalt on the road, automobile exhaust, etc.

5. Chronic malnutrition

Epidemiological surveys in some countries such as the United States and Japan have long found that long-term malnutrition has a certain relationship with lung cancer.

The survey found that people who often do not eat vegetables are 7 times more likely to develop cancer than those who often eat vegetables. The reason is that they lack vitamin E, vitamin B12, vitamin C, which increases the risk of lung cancer.

Doctor's reminder: If you have "2 pains and 1 convexity" on your body, it is recommended to check

[2 Pain]

1. Shoulder pain

The tip of the front of the lung is exactly the exit from the thoracic cavity, where many nerves are distributed.

That is to say, once there is cancer or inflammation in the apex of the lung. When the tumor occurs, it will form a pressure on the lung cavity, resulting in inflammation of the shoulder.

At the same time, the shoulder and back muscles can also feel pain. If you have this symptom, you should pay attention and go to the hospital to check the lung CT in time.

2. Chest pain

According to incomplete statistics, 50% of lung cancer patients often have various chest pains due to tumor compression on the chest wall or pleura.

When the intercostal nerve is compressed, it will cause chest pain. Therefore, if chest pain occurs frequently, it is necessary to check the heart and lungs in time.

【1 convex】

bulging fingers

Clinical studies have shown that patients with lung cancer will have prominent symptoms at the ends of the finger joints, accompanied by thickening and darkening of the skin.

The finger is medically known as the "clubbing finger", and the appearance of the finger often represents a lung disease or a respiratory disease. You can do a CT scan of your finger to rule it out.

Extension: How to prevent lung cancer? Four points to prevent lung cancer

1. Eat healthy

It is necessary to develop good eating habits in peacetime, not to eat spoiled food, and to eat as little as possible of various pickled foods.

When eating, pay attention to chewing slowly. Do not eat food that is too hot or too cold. For high-fat foods, eat as little as possible. You can properly eat more fresh fruits and vegetables and supplement your body with enough vitamins.

2. Stay away from alcohol and tobacco

Smoking and drinking increase the risk of lung cancer, so we need to stay away from them. Although we have always advocated not smoking and drinking, many old smokers and alcoholics have a hard time doing it.

For example quit smoking immediately. Quitting alcohol is hard. You can start by reducing the amount you smoke and drink each day and then gradually reduce until you don't smoke at all. Until you don't drink. At the same time, we should stay away from people who smoke and drink alcohol, in every person who has successfully quit smoking. In the phase of quitting drinking ourselves.

3. Exercise more

People who want to prevent lung cancer should actively exercise more, which can improve cardiopulmonary function through exercise. When the heart and internal function improve, it is often effective at keeping the area young and needed to help prevent disease.

Therefore, people who want to reduce the prevalence of lung cancer should delay physical aging and promote lung health through reasonable exercise.

4. Actively treat chronic lung diseases

People with tuberculosis, silicosis, pneumoconiosis, chronic bronchitis. People with chronic lung diseases such as diffuse pulmonary fibrosis have a higher risk of developing lung cancer than normal people. Therefore, we should actively treat these chronic lung diseases and reduce the risk of lung cancer.
