Los Angeles: Actress Shannen Doherty has opened up about her intense battle with cancer. The 45-year-old actress revealed last August that she was diagnosed with breast cancer in February 2015. Doherty told etonline.com: "It's hard. I started thinking that I wasn't going to live... I don't look past today." "I don't know if I'll ever look like me again," she added. However, Doherty is determined to beat the disease and is doing everything she can to fight it. "I want to believe that if I fight, I'm going to be okay," she said. Doherty recently shaved her head and posted photographs on Instagram, and her former "Beverly Hills 90210" co-star Jason Priestley called her "brave" for sharing her struggle.
