Does smoking cause breast cancer?
Smoking, including vaping, is a confirmed risk factor for developing many types of cancer, including breast cancer. Smoking also directly contributes to heart and other lung diseases, too. Additionally, secondhand smoke is also a risk factor for cancer. So if you are a smoker, help yourself in a significant way and join a smoking cessation program to help you stop. The day you stop smoking, the healing can begin, and each week in which you are smoke-free, you give yourself increasing advantages for a healthier life.
