Though mammograms do not show every breast mass, it is a very good tool for initial screening. There is a general consensus that women age 50 and older should get a mammogram annually. There is some controversy as to how often women age 40-50 should have a screening mammogram, but the American Cancer Society now recommends a mammogram every year for women over 40. During a mammogram, the breast is compressed or flattened and a x-ray is taken, producing a black and white image of the breast. Mammography can also be used as a diagnostic tool to evaluate changes in the breast found on examination.
Women discover most breast masses by themselves during the breast self-examination.
This exam allows a woman to become more familiar with her breast, making the detection of subtle changes or abnormalities easier. It is important to remember that most masses discovered are not cancerous, but they should be brought to the attention of your health care provider. Experts recommend monthly self-examination of the breasts. The BSE should be done 7-10 days from the beginning of your menstrual cycle. If your periods are not regular, perform the BSE on the same day each month.
