Screening for Breast Cancer May Spur Unnecessary Treatment

Bloomberg Top -- The report, published today in the Archives of Internal Medicine, found that the rate of cancer among women who received biannual mammograms over six years in four Norwegian countries was 22 percent higher than those who didn’t. That may mean that tumors in those who weren’t tested regressed without being treated, researchers said.

“Our findings simply provide new insight on what is arguably the major harm associated with mammographic screening, namely, the detection and treatment of cancers that would otherwise regress,” said the researchers led by Per-Henrik Zahl at the Norwegian Institute of Public Health‘s epidemiology department in Oslo.
