A mammogram, an x-ray image of the breast, is used to look for early signs of breast cancer. It can often detect changes in breast tissue before symptoms develop. Mammograms may also help identify abnormalities that require further evaluation, even if no cancer is present.
Mammography Screening Guidelines
For individuals at average risk, current guidelines referenced by the American Cancer Society include:
• Women between 40 and 44 have the option to start screening with a mammogram every year.
• Women 45 to 54 should get mammograms every year.
• Women 55 and older can switch to a mammogram every other year, or they can choose to continue yearly mammograms. Screening should continue as long as a woman is in good health and is expected to live at least 10 more years.
Because every patient’s risk is unique, recommendations may vary based on family history, genetics, and personal medical history.
Who May Need Earlier or More Frequent Breast Cancer Screening?
Some individuals may require a more personalized screening plan if they have:
• Have a lifetime risk of breast cancer of about 20% to 25% or greater, according to risk assessment tools that are based mainly on family history.
• Have a known BRCA1 or BRCA2 gene change, based on genetic testing.
• Have a first-degree relative (parent, brother, sister, or child) with a BRCA1 or BRCA2 gene change and have not had genetic testing themselves.
• Had radiation therapy to the chest before they were 30 years old.
• Have Li-Fraumeni syndrome, Cowden syndrome, Bannayan-Riley-Ruvalcaba syndrome, or another known hereditary cancer syndrome, or have a first-degree relative with one of these.
In these cases, earlier and/or more frequent imaging may be recommended by a specialist. This decision should be made with a woman's healthcare providers, considering her personal circumstances and preferences.
Breast cancer screening is a vital step in early detection and improved outcomes. Mammography remains the most effective screening tool for average-risk individuals, but screening recommendations should always be personalized.
