Causes of lung cancer in non-smoking women

What are the main risk factors of lung cancer? This is a question that many lung cancer patients want to know very much. Clinically, many patients who learn that they have lung cancer do not know how they contracted the disease. This is because patients do not fully understand the disease. If we want to cure lung cancer, we must know the main factors that cause the disease so that we can carry out symptomatic treatment. At present, the main causes of lung cancer include diet and nutrition, air pollution, occupational carcinogens, etc., which are specifically introduced as follows.

1. Diet and nutrition

Some studies have shown that people who eat less vegetables and fruits containing beta-carotene have a higher risk of lung cancer. People with low levels of beta-carotene in their serum also have a higher risk of lung cancer. Epidemiological survey data also show that eating more green, yellow and orange vegetables and fruits containing beta-carotene and foods containing vitamin A can reduce the risk of lung cancer. This protective effect is particularly evident for current or former smokers.

2. Air pollution

Air pollution includes indoor micro-environment and outdoor macro-environment pollution. Passive smoking, fuel combustion and cooking in indoor environment may produce carcinogens. Data show that using coal indoors, contact with coal smoke or its incomplete combustion products are risk factors for lung cancer, especially for female adenocarcinoma. The oil smoke released by heating during cooking is also a carcinogenic factor that cannot be ignored. In the atmosphere of heavy industrial cities, there are carcinogens such as 3,4-benzopyrene, arsenic oxide, radioactive substances, nickel, chromium compounds and non-combustible aliphatic hydrocarbons.

3. Occupational carcinogens

The confirmed occupational factors that cause lung cancer in humans include asbestos, arsenic, chromium, nickel, beryllium, coal tar, mustard gas, trichloromethyl ether, chloromethyl methyl ether, heating products of tobacco, radon and radon protons produced by the decay of radioactive substances such as uranium and radium, ionizing radiation and microwave radiation. These factors can increase the risk of lung cancer by 3 to 30 times. Among them, asbestos is a recognized carcinogen. The incidence of lung cancer, pleural and peritoneal mesothelioma in those exposed to it is significantly increased, and the incubation period can be up to 20 years or longer. The lung cancer mortality rate of smokers exposed to asbestos is 8 times that of non-exposed smokers.

Through the introduction of "What are the main risk factors of lung cancer", I believe everyone has already understood that in order to cure lung cancer, patients must choose an appropriate treatment method. I wish every patient can stay away from the torture of lung cancer as soon as possible.
