What causes lung cancer in women? Several key causes of lung cancer in women

It can be said with certainty that basically all lung cancer patients are more or less related to smoking, which is one of the key factors causing lung cancer clinically. Of course, this is not absolute, and it does not mean that smoking will definitely cause lung cancer. It just means that this is one of the key groups of lung cancer. The following is a specific introduction to this aspect:

1Lung cancer in women is increasing faster than in men

In the United States, from 1990 to 2003, the incidence of lung cancer in men remained stable, while the number of new cases in women increased by 60%. This increasing trend has been called the "epidemic of the times."

According to statistics from the National Cancer Office in my country, from 2000 to 2005, the number of male lung cancer cases increased from 260,000 to 330,000, an increase of 26.9%; the number of female lung cancer cases increased from 120,000 to 170,000, an increase of 38.4%!

Smoking is the main cause of lung cancer. Many men smoke, so when it comes to tumors, lung cancer ranks first among men.

What about women? In the past decade (1999 to 2009), the incidence of lung cancer in women has been on the rise. It ranks second only to breast cancer in the ranking of tumors.

The growth rate of lung cancer in women is faster than that in men, but the number of female smokers has not increased significantly?

Why are more and more women who have never smoked developing lung cancer?

Medical scientists therefore speculate that women may have other risk factors for lung cancer.

2Women are more afraid of environmental pollution

Epidemiological studies have shown that women are more susceptible to carcinogenic pollutants in the environment.

For example, non-smoking women whose spouses smoke have a 24% increased risk of developing lung cancer.

Women who grow up surrounded by smoke from their smoking fathers have a significantly increased risk of lung cancer.

Among Chinese female lung cancer patients, about 60% have a history of long-term exposure to kitchen fumes. The probability of developing lung cancer from "frequent exposure to the kitchen" and "frequent smoking" is almost equal.

Epidemiological studies have also shown that women are more susceptible to lung cancer than men. In other words, if exposed to the same polluted environment, men are more likely to develop lung cancer than women.

like--

Smokers: At any set smoking level, the incidence of lung cancer in female smokers is 0.5-1.0 percentage points higher than that in male smokers.

Non-smokers: The incidence of lung cancer in non-smoking women is twice that of non-smoking men.

The chance of developing lung cancer is much higher for people who inhale secondhand smoke than for normal smokers. This shows that smoking not only endangers one's own health, but also causes great harm to others. It should be noted that clinical data show that the younger the age at which one starts smoking, the greater the chance of developing lung cancer.
