Valerie Harper diagnosed with terminal brain cancer

One of the sitcom greats, Valerie Harper, is reportedly suffering from terminal cancer.

In an upcoming interview with People magazine, Harper revealed that she has incurable brain cancer that carries with it a grim diagnosis of just a few months to live. Known as leptomeningeal carcinomatosis, the condition is marked by cancer cells spreading into the fluid-filled membrane which surrounds the brain. The actress received the diagnosis on January 15th, with doctors telling Harper she has as little as three months before she will succumb to the disease.

Harper was a fixture in 1970s and 1980s television, playing Rhoda Morgenstern, the affable everywoman from the Bronx, on the classic sitcoms "The Mary Tyler Moore Show" and "Rhoda." More recently, she has made guest appearances on series such as Lifetime's "Drop Dead Diva" and ABC's "Desperate Housewives."

The TV legend has fought off cancer before, enduring treatment for lung cancer in 2009. Despite the diagnosis, the actress remains in good spirits and with a positive outlook. "I don't think of dying," Harper told People magazine. "I think of being here now."

The 73 year old actress continued, "I'm well past my expiration date already. I've had a good run, what more can I ask for?"
