Women are likely to undergo preventative mastectomy if they test positive for the breast cancer genes, despite other less invasive treatment options.
Researchers at MD Anderson Cancer Center surveyed more than 300 women who underwent genetic screening tests for breast cancer. They found 70 percent who had the breast cancer genes thought mastectomy was the best way to prevent the disease, 65 percent thought the surgery was the only way to reduce their anxiety. 80 percent of women who thought mastectomy was the best way to beat the disease eventually had the surgery.
Researchers say understanding a woman's opinion of a breast cancer gene diagnosis can help determine their treatment.
