CANCER DIGEST – May 21, 2014 – Many women who have breast cancer in one breast may be opting for double mastectomy for reasons other than a genetic or family history of the disease indicating a high risk of cancer in the other breast. Researchers who analyzed data from 1447 women with breast cancer who were followed and surveyed twice over a five year period found that 32.2 percent considered having both breasts removed, 45.8 percent received single mastectomy and 22.8 percent received breast conserving surgery, or lumpectomy. Among the the 7.6 percent who actually underwent double mastectomy most had an MRI and were more likely to fear recurrence. Few had a clinically significant risk of developing cancer in the other breast. The study published today in the journal JAMA Surgery concluded that more research is needed to understand the factors driving the use of double mastectomy.
