mastectomy

Shannen Doherty reveals her cancer has spread

"I had breast cancer that spread to the lymph nodes, and from one of my surgeries we discovered that some of the cancer cells might have actually gone out of the lymph nodes," Doherty said. "So for that reason, we are doing chemo, and then after chemo, I'll do radiation."

Doherty, who was diagnosed with breast cancer in February 2015, called the mastectomy "traumatic and horrible." But said the trauma of the surgery hit her when she got fitted for a new bra.
