Smoking has a very big impact on women, and it is recommended that women do not smoke. A cigarette contains 6000 kinds of harmful substances and 400 kinds of carcinogenic substances. Smoking can cause 11 kinds of tumors, including nasopharyngeal cancer, oral cancer, lung cancer, liver cancer, esophageal cancer, stomach cancer, breast cancer, etc. Therefore, smoking is harmful but not beneficial. In addition to causing the above tumors, smoking can also have a significant impact on the surrounding population. The harm of secondhand smoke is far greater than that of firsthand smoke, so female patients must quit smoking in public. Smoking can also lead to infertility and adversely affect young children, which is the harm of third-hand smoke. Therefore, the effects of smoking on women are so extensive that female patients are advised not to smoke.
