TV legend Valerie Harper reveals in this week’s People that she’s been diagnosed with incurable brain cancer and has about three months to live.  Harper, best known for playing Rhoda Morgenstern on The Mary Tyler Moore Show and Rhoda, was diagnosed in January with leptomeningeal carcinomatosis, a terminal condition where cancer cells spread into the membrane surrounding the brain. “I don’t think of it as dying,” says the 73-year-old. “I think of being here now.” Harper, who beat lung cancer in 2009, adds, “I’m well past my expiration date already. I’ve had a good run, what more can I ask for?”

MARY TYLER MOORE DEVASTATED BY HARPER NEWS

One day before going public with the news of her illness, Valerie Harper called her longtime co-star Mary Tyler Moore and told her the sad news. “I'm absolutely devastated by this news," says Moore, 76, who herself underwent surgery in 2011 for a benign tumor in the same spot where Harper's malignant cancer cells are located. "Valerie has given so much joy, laughter and love to the world. I join her fans and send much love and positive thoughts to her and her family during this difficult time."
