As long as women understand the pros and cons of the procedures, "it really does become a very personal choice," she added.
Dr. Len Lichtenfeld, deputy chief medical officer for the American Cancer Society, agreed. Doctors need to communicate these study findings to their patients who are deciding about surgical treatment of their breast cancer, he said.
Lichtenfeld, who had no part in the study, advises women to take time after their diagnosis to learn about the pros and cons of each approach.
No matter which option she chooses, a woman's decision about surgical treatment needs to be respected, Lichtenfeld said. "If a woman is educated [about her options] and makes a decision, that is her decision."
