How often should breast cancer survivors have mammograms post-treatment?

Breast cancer survivors are generally recommended to have mammograms annually after their treatment is completed. This guideline is based on evidence suggesting that regular surveillance through mammography is essential for the early detection of any recurrence of cancer or the emergence of new breast cancers. Annual mammograms allow for consistent monitoring of the breasts, which is particularly important for survivors who may still be at increased risk of developing breast cancer in the years following their initial diagnosis and treatment.

While more frequent screening, such as every six months, might seem beneficial for some patients, it is not typically advised as part of the standard follow-up care due to factors like potential overdiagnosis, increased anxiety, and unnecessary medical interventions. Similarly, although mammograms every two or three years are recommended for average-risk women, these intervals are considered insufficient for those with a history of breast cancer, who require closer monitoring to ensure timely intervention if needed. Hence, the annual schedule strikes a balance between vigilant oversight and patient safety.
