Take estrogen only for as long as necessary. And avoid unnecessary exposure to x-rays. For more information on cancer risk, consult your health care provider. Some risk factors are avoidable, while others can't be controlled. One of the most avoidable risk factors is tobacco.
Smoking is linked with a number of cancers including cancer of the lung, bladder, mouth, and cervix.
Smoking, chewing, and dipping tobacco are also the most common risk factors for oral cancer. Alcohol is the second leading avoidable risk factor associated with stomach, esophagus, breast, throat, oral cavity, and liver cancers. A family history of cancer is one of the unavoidable risks. This is especially true in breast cancer. If a close relative, particularly your mother or sister, has had breast cancer, your risk is automatically increased.
