1. Avoid Oral Contraceptives and Hormone Replacement Therapy
In 2007, the World Health Organization declared that both oral contraceptives and hormone replacement therapy were Group I Carcinogens—in other words, they are known to cause cancer in humans. There is no longer any doubt that both of these drugs increase the risk for breast cancer. Stopping the use of them reduces that risk, not immediately, but slowly over time. So whenever possible, avoid the use of oral contraceptives and hormone replacement therapy.
2. Don’t Smoke
Smoking is just plain bad for you and it’s bad for your breasts, too. It increases the risk for breast cancer, especially in women who begin smoking in their teenage years. And if you have breast cancer and you continue to smoke, you increase your risk of dying. So, please, don’t smoke. Stop, if you do.
