Study: 1 in 3 breast cancer patients overtreated

LONDON—One in three breast cancer patients identified in public screening programs may be treated unnecessarily, a new study says. Karsten Jorgensen and Peter Gotzsche of the Nordic Cochrane Centre in Copenhagen analyzed breast cancer trends at least seven years before and after government-run screening programs for breast cancer started in parts of Australia, Britain, Canada, Norway and Sweden.

Once screening programs began, more cases of breast cancer were inevitably picked up, the study showed. If a screening program is working, there should also be a drop in the number of advanced cancer cases detected in older women, since their cancers should theoretically have been caught earlier when they were screened.  

However, Jorgensen and Gotzsche found the national breast cancer screening systems, which usually test women aged between 50 and 69, simply reported thousands more cases than previously identified.

Overall, Jorgensen and Gotzsche found that one third of the women identified as having breast cancer didn’t actually need to be treated.

Some cancers never cause symptoms or death, and can grow too slowly to ever affect patients. As it is impossible to distinguish between those and deadly cancers, any identified cancer is treated. But the treatments can have harmful side-effects and be psychologically scarring.
