Shannen Doherty's breast cancer has spread

Los Angeles :Actress Shannen Doherty has revealed that her breast cancer has "spread to the lymph nodes". The 45-year-old actress revealed last August that she was diagnosed with breast cancer in February 2015.  "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 told  "So for that reason, we are doing chemo, and then after chemo, I'll do radiation," she added.  The former "Beverly Hills" star also revealed she had a single mastectomy in May and is open about the most difficult part of fighting cancer. "The unknown is always the scariest part. Is the chemo going to work? Is the radiation going to work? You know, am I going to have to go through this again, or am I going to get secondary cancer? Everything else is manageable. "Pain is manageable, you know living without a breast is manageable, it's the worry of your future and how your future is going to affect the people that you love," she added.  However, Doherty has found support from her team of doctors, including the surgeon who performed her mastectomy. "He didn't want me to wake up with absolutely nothing. It was very important to him that I didn't have that experience, and so, he put an expander in, so I have a tiny something there. It's cute and sometimes we fill it up and make it bigger, and sometimes we reduce it," she said.
