Farrah Fawcett has been diagnosed with cancer, and is maintaining a positive attitude to get through it, she said. "I am determined to bite the bullet and fight the fight while going through the next six weeks of cutting edge, state-of-the-art treatment,'' the 59-year-old former "Charlie's Angels'' star said Friday in a statement released by her publicist, Mike Pingel. "I should be able to return to my life as it was before.'' Pingel only said it was recently diagnosed and involves a fast-growing tumour. The actress, who appeared with her former "Charlie's Angels'' co-stars at an August Emmy tribute to the late TV producer Aaron Spelling, said she has been overwhelmed by the "outpouring of concern, love, prayers and compassion'' she has received from people around the world."I deeply believe in one's own positive will to overcome even the most daunting challenges,'' she said.
