Prophylactic surgery greatly reduces cancer risk, but by how much is unclear
The risk reductions suggested by studies examining the value of prophylactic surgery for the prevention of breast and ovarian cancer in high-risk women may be over- or underestimated because of potentially unrecognized biases in study design, according to a commentary in the July 2 issue of the Journal of the National Cancer Institute. Understanding these biases might help researchers better evaluate past studies and improve the design of future studies.
