A double mastectomy to beat breast cancer will not improve chances of survival, study reveals
NY Post
The double mastectomy, undertaken by some breast cancer patients as a precautionary measure, provides no advantage to sufferers when it comes to survival, a new study has revealed.
The findings, published this week in JAMA Oncology, are based on analysis of more than 660,000 women diagnosed with breast cancer during the years 2000 and 2019.
Those choosing a double mastectomy — a procedure to remove both breasts, even if only one is affected by the cancer — were shown to have no advantage over those who had a less final lumpectomy, or a mastectomy, People reported.
Women opting for the latter had a 7% chance of finding cancer in the other breast later on.
The two-decade study showed similar death rates in all three groups — 8.5% for lumpectomies, 9% for mastectomies and 8.5% for double mastectomies.
“If you get a contralateral breast cancer, your risk of dying goes up. But preventing it doesn’t improve your survival,” said Dr. Steven Narod at Toronto’s Women’s College Hospital.
