There are four main causes of lung cancer in women: second-hand smoke, oil smoke, haze and stress

In recent years, the incidence and mortality of lung cancer have increased rapidly, especially the increasing number of female patients. Experts point out that smoking, air pollution, fumes and stress are the main causes of lung cancer.

A survey conducted by the Department of Radiotherapy and Chemotherapy of the First Affiliated Hospital of Wenzhou Medical University showed that:

Nearly 80% of lung cancer patients have a long history of smoking. Xie Congying, director of the radiotherapy and chemotherapy department, said, "For non-smokers with lung cancer, the main cause of the disease comes from the external environment."

Twenty percent of female lung cancer patients never smoke, and the reason they develop lung cancer may be due to secondhand smoke. The smoke inhaled from passive smoking is more harmful to the human body than active smoking and is more likely to cause lung cancer. Some women who live with smokers have a 6 times higher chance of developing lung cancer than normal people.

In addition to cigarettes, oil smoke is also an important factor in women getting lung cancer

The fumes produced by home cooking are the main source of pollution in the kitchen environment. Women have more opportunities to cook and are more vulnerable to thick smoke. If they use rapeseed oil to stir-fry or fry food, it will emit fumes containing chemical mutagens. Or if they use inferior oil that has been stored for too long, it contains many free fatty acids, aldehydes, and ketones. When the oil temperature reaches a certain level, it is easy to emit fumes containing a variety of harmful substances. These fume particles have been proven to be carcinogenic. Surveys show that this cause is particularly prominent in middle-aged and elderly female lung cancer patients, and the risk factor is three times that of normal people. However, these hazards are slow, long-term factors that cause lung cancer and have not attracted widespread attention from society and women.

However, another hidden carcinogen, "mental stress", always invisibly reduces people's immunity.

This gives cancer cells an opportunity to multiply and worsen. The role tension of women causes heavy psychological pressure and mental burden. In the current period of social transformation, women will be subjected to psychological shocks from work, family, emotions and other aspects in the process of playing their specific professional and family roles, which can easily lead to role tension for women, resulting in mental and physical exhaustion, long-term depression, excessive stress, and some psychogenic diseases. During this period, immunity will be reduced, which lays a dangerous root for the occurrence of lung cancer in women.

It is understood that the cure rate of lung cancer detected in the early stage can reach about 80%, but in fact, the vast majority of patients are discovered in the terminal stage. Therefore, experts suggest that most symptoms of early lung cancer are irritating dry coughs. Patients over 40 years old with coughs lasting for 3 months are advised to go to the hospital for a check-up. Early detection can lead to early cure.
