How many causes are there for lung cancer? 5 causes are very likely to induce lung cancer

Many people think that only smokers will get lung cancer. In fact, there are many causes of lung cancer. Even non-smokers can still get lung cancer. So how many causes are there for lung cancer? Occupational factors, diet and nutrition factors, ionizing radiation, genetic factors, environmental factors, etc. are all important causes of lung cancer.

When it comes to lung cancer, the first thing that comes to mind is that it is a disease that only long-term smokers will get. However, with the development of society, there are more and more factors that lead to lung cancer. There are always causes of lung cancer around us, and every aspect of life is a risk factor for lung cancer. Let's learn about the causes of lung cancer with the introduction of experts.

1. Occupational factors

Many people are often exposed to carcinogens due to work, such as workers in chemical factories. Their working environment determines their exposure to asbestos, arsenic, chromium, soot, tar, polycyclic aromatic hydrocarbons in petroleum, and radiation, etc. These substances can cause lung cancer.

2. Diet and Nutrition Factors

Some people are picky eaters for a long time or do not take in enough vitamins. Bad eating habits are also an important cause of lung cancer.

3. Ionizing radiation

As technology develops, there is more and more radiation, which comes from natural sources, medical exposure or other sources.

4. Genetic modifiable factors

Studies have found that lung cancer is also somewhat hereditary. If a lung cancer patient has a family history or a history of other tumors, gene mutations may also lead to lung cancer.

5. Environmental factors

As air pollution becomes increasingly serious, haze has also become an important cause of lung cancer. This is because the bacteria in the air will enter the lungs along with pM2.5, then cause damage to the alveoli, and then cause lung cancer.

Although men are more likely to get lung cancer than women, and men who smoke are more likely to get lung cancer than men who don't smoke, this doesn't mean that non-smokers won't get lung cancer. In addition to smoking, there are many other causes of lung cancer. Experts remind us to do a good job of preventing lung cancer, pay attention to developing good eating habits and actively exercising, and stay away from lung cancer by improving our own immunity.
