There is no doubt that smoking is harmful to health and will greatly increase the probability of getting lung cancer. Some people have smoked for a lifetime, but there is no sign of lung cancer, but some people may have the risk of lung cancer even if they have good living habits, do not smoke or drink, exercise every day, and eat a healthy diet. Obviously, there is no necessary connection between smoking and lung cancer, and there is a certain chance of getting lung cancer without smoking. Cancer is the result of the combined effects of multiple factors.

Lung cancer has occupied the top spot in the cancer list for a long time. It is called the number one killer of cancer because of its high morbidity and mortality. Smoking is a direct risk factor for lung cancer. Tiny particles in the lungs can cause lung cell death and repeatedly damage lung tissue, resulting in lung cancer.

Over 1 million people die from smoking every year in my country, tobacco smoke contains at least 69 kinds of carcinogens, inhalation of second-hand smoke causes lung cancer The rate is more than 6 times of normal people… In my country, more than 80% of female lung cancer patients have never smoked! Then what is the cause of these people suffering from cancer?

In fact, in addition to our daily living habits and environmental factors that cause lung cancer, genetic factors and aging may be the cause of the increase in the incidence of lung cancer.

The following editor will take you to see what are the high-risk factors for lung cancer?

Smoking and passive smoking.

Smoke contains a variety of carcinogens, which can induce gene mutations and are the most common cause of lung cancer. Passive smokers, also known as “second-hand smokers”, have a higher risk of cancer than smokers themselves. Although second-hand smoke is second-hand, it is far better than first-hand smokers. Women who live with second-hand smokers for a long time The probability of suffering from lung cancer is 2.6-6 times that of the general population.

Air pollution.

Industrial waste gas and automobile exhaust in the city may cause air pollution. If the cooking fume in the kitchen is not discharged in time, it will also constitute indoor air pollution. Long-term inhalation of highly polluted air has a lung cancer risk comparable to passive smoking.

Occupational and environmental exposure.

There are many carcinogens in the labor environment of certain occupations, such as radon gas, asbestos, chromium, nickel, arsenic, coal tar, etc.

Ionizing radiation.

The lungs are more sensitive to radiation and are easily affected by them.

Prior chronic lung disease.

Cancer may develop during the course of the disease, but is less common.

Genetic factors.

People with a history of malignant tumors and family history belong to the high-risk group. Genes are also an important factor. Many studies have shown that if immediate family members suffer from lung cancer, the probability of family members suffering from lung cancer is higher than that of the general population.

In recent years, medical death data show that the number of deaths due to lung cancer is increasing. In order to prevent problems before they happen, start from now, start from yourself, usually pay more attention to lung maintenance, quit smoking and other bad habits, and avoid lung cancer infection.

Here I will list some measures to prevent lung cancer:

1. Stay away from cigarettes, and say bye-bye with cigarettes.

2. Take good care of yourself in high-risk occupations, and pay attention to avoid contact with polluted air, smoke and oil fume in your life, and do a good job of ventilation indoors.

3. ​​Develop good living habits, choose a suitable exercise method, maintain a happy mood, and help strengthen immunity.

4. Healthy diet, balanced nutrition, eat more whole grains, fresh vegetables and fruits.

5. High-risk groups should be vigilant and have regular physical examinations. Low-dose helical CT is the best choice for cancer screening.

How to determine the risk of lung cancer? Primary lung cancer usually has the following symptoms in the early stage: cough, cough Blood, dyspnea, chest pain, fever, weight loss, when these warning signs appear, be vigilant! Timely medical treatment, early examination, active treatment, early detection, Early diagnosis and early treatment are very critical to the prognosis of lung cancer. Regular life, balanced diet, and proper exercise are all important foundations for maintaining health and preventing and controlling lung cancer.
