Magnetic resonance imaging, better known as MRI, has been considered effective in detecting breast cancer in women with dense breast tissue and those with the BRCA mutation.
But a study in the British medical journal The Lancet finds little evidence the MRIs improve patient outcomes. Nor did MRI reduce the number of surgeries a women had to undergo.
The authors say MRIs are still useful guides in chemotherapy and radiation therapy for women having breast conserving surgery.
