Long-term study shows screening mammography doesn’t reduce mortality.

Yesterday, a Canadian study group published the final follow-up results of a long-term randomized controlled trial in the BMJ, showing that screening mammography had no mortality benefit for middle-aged women, and that screening has the potential to cause substantial harm.

The study, which shows that mammography offered no more benefit than physical breast examinations, but overdiagnosed breast cancer in a number of women, is in line with other studies showing that screening mammography does not reduce mortality, and that breast cancer is commonly overdiagnosed and overtreated.

Women who are considering getting screened need to understand the possibility of overdiagnosis, and the potential harm from being treated unnecessarily, especially in a medical environment that heavily promotes such tests as the only responsible way to manage one’s health.
