Mammography
A screening mammogram is an X-ray used to detect breast changes in women who display no signs or symptoms of breast cancer. It is currently the best available tool for detecting breast cancer; however, women must be aware of its capabilities and limitations.
Breast Cancer Network of Strength suggests the following:
-
Women should discuss the benefits and risks of screening with their health care providers.
-
Screening should occur every 1-2 years for women 40-49 years of age and annually for those 50-69. For those 70 and older, screening should continue as long as women maintain good health and have no other prohibitive medical conditions.
-
Women who are younger than 40 should consider, in consultation with their healthcare provider, to have regular screening mammograms if they:
-
have an extensive family history of breast or ovarian cancer;
-
had irradiation at a young age in the area of the breast;
- carry the BRCA1 or BRCA2 gene mutation; and/or
- are planning breast reduction surgery
-
-
Any abnormality found on a screening mammogram should be discussed with a physician and followed up appropriately.
-
Women—and men—of any age who have unusual changes in their breasts (e.g., lump, dimpling, skin irritation and nipple discharge) should consult a healthcare provider and together consider having a diagnostic mammogram.

Given the lack of clear evidence on the timing of screening mammograms, women should consult with their physicians to determine a schedule best for themselves.
