1 What are the early symptoms of lung cancer 1. Cough

Cough is the most common early symptom of lung cancer. It is mainly paroxysmal irritating choking cough, and sometimes the cough is not clear. It seems that these patients generally have no sputum or only a small amount of white foamy sputum, and purulent sputum may appear due to secondary infection. 2. Hemoptysis

Hemoptysis is very common in patients with lung cancer. It is mostly due to occasional blood streaks in the sputum. This is the first symptom in about one-third of patients. 3. Chest pain

Many people have experienced chest pain, which is usually persistent. More commonly, pain occurs because the tumor has invaded other tissues. 4. Fever

Cancerous fever is generally high fever, and in the case of cancerous fever, the fever symptoms will improve after the tumor is removed. This is caused by tumor invasion.

Special reminder: We cannot identify it as a lung tumor simply because of cough, sputum, or hemoptysis. We should go to the hospital for professional examination.

2 High-risk groups for lung cancer

1. Those aged 55 to 74 years old, with a cumulative smoking volume of more than 30 packs per year, including quitting smoking for less than 15 years.

2. Aged 50 years or older, with a cumulative smoking volume of more than 20 packs per year, and at least one risk factor other than second-hand smoke. 3 High-risk factors for lung cancer

1. Smoking

Smoking is the main risk factor for lung cancer. 87% of lung cancer cases can be attributed to tobacco exposure. The risk of lung cancer for smokers is not 24 times more than smokers.

2. Environmental factors

The working environment of chemical factory workers is very poor, and there are many toxic particles in the air; traffic police are exposed to the road every day and inhale a large amount of car exhaust, among which Harmful gases can also cause lung cancer; teachers are exposed to chalk dust every day, and this substance has strong adsorption properties.

3. Long-term exposure to oil fume

The kitchen ventilation effect is poor, coupled with the large amount of harmful substances such as liquefied petroleum gas and kitchen oil fume, which can also induce lung cancer when inhaled by chefs.

4. Genetic factors

Lung cancer has a certain hereditary tendency and there is a phenomenon of family aggregation. If there is a history of lung cancer in your family, you should be careful and have regular physical examinations. 4 How to prevent lung cancer

1. Quit smoking

Tobacco contains many carcinogens. Statistics show that the risk of lung cancer caused by smoking is too great. It takes more than 20 years of quitting smoking to basically eliminate the risk of lung cancer brought by smoking and reduce it to the risk level of a non-smoker. The risk of death from other diseases caused by smoking also requires more than 20 years of quitting smoking to eliminate.

2. Pay attention to environmental protection

Choose gasoline that meets standards, use environmentally friendly indoor decoration materials, improve indoor ventilation environment, reduce the concentration of indoor toxic substances, and do a good job in haze days protective measures.

Eat less fried, barbecued and other hot foods. These foods are low in nutrients and difficult to digest, and some contain carcinogens such as benzopyrene.

Avoid eating too much sugar and high-fat foods. Sugar has a carcinogenic catalytic effect and will consume the few minerals and B vitamins in the body, reducing the body's disease resistance.

4. Pay attention to and insist on annual physical examinations

People at high risk of lung cancer should try to have anteroposterior and lateral chest X-rays every year. For cases where problems are suspected, ordinary CT scans or even spiral CT scans should be performed. CT detailed examination. Adherence to physical examination can lead to early detection and early treatment.

5. Regular life, balance work and rest
