When a woman has been diagnosed with breast cancer, one of the most common options of treatment is a mastectomy. An increasing number of women are choosing to have double mastectomies, even when the cancer only appears in one breast. But a new study, conducted by the University of Michigan Comprehensive Cancer Center, concluded in most cases a double mastectomy is unneeded.

Researchers followed the cases of 1,447 women who were diagnosed and treated for cancer in one breast and had not had cancer show up in the other breast. Eight percent of the women in the group had opted for a double mastectomy – medically referred to as a contralateral prophylactic mastectomy (CPM). The data showed that women with higher education levels, as well as women who had undergone an MRI prior to treatment, were more likely to choose a CPM.

Seventy percent of the women who chose to have a CPM did not have a strong family history of breast or ovarian cancer. They also did not test positive for mutated BRCA genes. A positive test to mutated BRCA genes indicates a strong likelihood of breast (and ovarian cancer). It is medically recommended that women who test positive undergo CPM.

The researchers concluded that undergoing a CPM offers no increase in survival rates because of the low rate of recurrence of cancer showing up in the other breast when just a single mastectomy is performed. In the study, only three percent of women had a recurrence.

The study, which was published in the medical journal JAMA Surgery, also points out that women who opt for CPM face much longer and more difficult recovery times, not only for the CPM surgery, but also for the reconstructive surgery that many women choose to have.
