Researchers at Mayo Clinic say women with cancer in a single breast are increasingly choosing to have both breasts removed to reduce the risk of future cancer.

Mayo surveyed "hundreds of women" who had double mastectomies between 1960 and 1993 "and found that nearly all would make the same choice again."

Findings of the study are in the Annals of Surgical Oncology.

Researchers were surprised that women who did not get reconstructive surgery were more likely to be satisfied with the double-mastectomy decision. Those who got reconstructive surgery, but dealt with complications "were likelier to regret their prophylactic mastectomy, though overall, most women with breast reconstructions were satisfied with their choices."
