Women with early-stage hormone-negative breast cancer who undergo a lumpectomy—often called breast-conserving therapy—fare slightly better than those who undergo a mastectomy, according to research presented today. And women from both groups do well, with the great majority alive after four years.
Specifically, those under 50 with lumpectomies were 13 percent to 29 percent less likely to die from their cancer than women with mastectomies. Women over 50 with hormone-negative who underwent a lumpectomy were 17 percent less likely to die than those with a mastectomy. The variation in percentages relates to variations in tumor sizes.
Data on 114,277 women from the California Cancer Registry were evaluated; 62,770 of these had a lumpectomy followed by radiation and 51,507 had a mastectomy. Ninety-three percent of the lumpectomy group and 87 percent of the mastectomy group were alive four years after diagnosis.
