In most cases women with breast cancer will have some sort of surgery as part of their breast cancer treatment. There are several breast cancer surgeries that our breast cancer surgeons specialize in, which include lymph node biopsy, lumpectomy, breast conserving surgery, mastectomy, breast reconstruction during mastectomy and breast reconstruction after mastectomy. Bedford Breast Center’s breast cancer surgeons are among the top surgeons in the field today, and we are dedicated to providing the highest standard of breast reconstruction in Beverly Hills and the greater Los Angeles area, every day.
