Shannen Doherty cancer has spread, report

Actress Shannen Doherty says her breast cancer has spread in an interview with Entertainment Tonight.

"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 tells ET's Jennifer Peros. "So for that reason, we are doing chemo, and then after chemo, I'll do radiation."

Doherty also told the entertainment show that she had a single mastectomy in May.

Last month, Doherty posted several pictures on Instagram showing her in various stages of cutting off her hair.

She preceded the series of photos with one showing hair clippers, a cupcake pan and a box of chocolates. In the caption she added, "#cancersucks."

Doherty's cancer was publicly revealed in a lawsuit filed against her former business managers last year. She claimed they mismanaged her money and allowed her health insurance to lapse. She said she didn't go to the doctor until she had insurance and there was a delay in diagnosing the cancer.

The 45-year-old Doherty is best known for her role as Brenda Walsh on "Beverly Hills, 90210."
