PHILADELPHIA (CBS) - Breast cancer is the most common non-skin cancer and the second leading cause of cancer death in North American women.
A mammogram is the only screening test shown to reduce breast cancer-related mortality.
There is general agreement that mammography should be offered at least every two years for women from 50 to 74. Between 40 and 50 years of age there have been debates over the frequency of mammograms. At the present time most experts say that you should talk with your doctor about your individual situation and risks.
Probably the most important message is to continue to have regular examinations and be aware that it is a potential risk.
