Overdiagnosis of Breast Cancer in Older Women Raises Treatment Risks

A study published in the Annals of Internal Medicine found that a significant number of American women aged 70 to 85 are potentially overdiagnosed with breast cancer, leading to unnecessary treatment. Overdiagnosis refers to the detection of breast cancers on screening that would never have caused symptoms or become clinically apparent. Technological advancements in screening have made it easier to detect even the smallest cancers, but not all of these cancers are destined to grow, spread, or be life-threatening. Overtreatment can increase the risk of complications, cause stress, and financial burden. The decision to get screened should be individualized, taking into account age, life expectancy, and overall health. More research is needed to determine whether mammograms are beneficial for older women, and the future of breast cancer diagnosis lies in cancer genomics and personalized treatment.
