Can advanced lung cancer infect people? 7 risk factors for lung cancer you should know

Lung cancer is now the number one killer of human health. With serious environmental pollution and smoking, more and more people are suffering from lung cancer. Quitting smoking as soon as possible can effectively prevent it, because the number of deaths caused by lung cancer has been increasing. So do you know who is prone to lung cancer? The following experts will introduce to you who is prone to lung cancer.

Everyone knows that a healthy lung is very important, because we can't breathe without it. So if we have lung disease, we must treat it in time to avoid delaying the disease from becoming more serious. For example, many lung cancer patients are caused by unhealthy daily living habits. Of course, many people are also worried about whether lung cancer is contagious. Can advanced lung cancer be contagious? Let's learn about the pathogenic factors of lung cancer:

Risk factors for lung cancer:

1. Middle-aged and elderly people

Middle-aged and elderly people are one of the high-risk groups for lung cancer, especially those over the age of 55. Due to their decreased immunity and deterioration of physiological functions, the disease is very easy to occur.

2. People who smoke for a long time

Smoking is harmful to health. Every smoker will see this sentence on the cigarette box. Indeed, cigarettes contain a lot of harmful substances that can easily affect the human respiratory organs, not to mention the lungs as the largest respiratory organ of the human body.

3. People living in areas with severe air pollution

Studies have shown that people who often live in an environment with severe air pollution have a 60% higher chance of developing lung cancer than the average person.

4. People who are exposed to coal smoke or oil smoke for a long time

5. Ionizing radiation: Large doses of ionizing radiation can cause lung cancer. Different rays of radiation produce different effects. For example, Hiroshima in Japan released neutrons and gravitational rays, while Nagasaki only released gravitational rays. The former has a higher risk of lung cancer than the latter.

6. Diet and nutrition: Animal experiments have shown that vitamin A and its derivative beta-carotene can inhibit tumors induced by chemical carcinogens.

7. Others: Viral infection, fungal toxins (Aspergillus flavus), tuberculosis scars, low immune function, endocrine disorders and family inheritance may also play a certain combined role in the occurrence of lung cancer.
