Currently, the incidence and mortality rate of lung cancer is the highest among all cancers, both in China and in the world, especially in China, where lung cancer is out of a period of rapid growth. According to statistics, the incidence rate of lung cancer among men is higher than that of women, but the incidence rate of lung cancer among women is gradually increasing faster than that of men. The reasons for this may include the following aspects: 1. Women are the main contactors of kitchen fumes, which, like smoke from smoking, are “biological fumes” that can cause lung cancer; 2. 3. The growth rate of female smokers is higher than that of male smokers, especially among some young women, and smoking has become a fashion; 4. More and more working women have to be exposed to the ubiquitous second-hand and third-hand smoke; 5. To prevent the occurrence of lung cancer, contemporary women need to do the following: 1. minimize frying, deep-frying, baking and other cooking methods that easily produce grease and smoke, and install suitable hoods in the kitchen; 2. stay away from indoor decoration pollution as much as possible, especially in their own homes, and choose simple decoration or qualified decoration materials; 3. quit smoking; 4. stay away from second-hand and third-hand smoke, and encourage relatives and friends around them to quit smoking; 5. 5. Relax your mind and reduce stress.
