Gwyneth Paltrow`s cancer fears

London: Actress Gwyneth Paltrow says she suffered so much pain while learning the guitar for her role as a singer in "Country Strong" that she feared she had cancer.

"My fingers wouldn`t respond to the signals my brain was giving them. I thought, I must have all these atrophied muscles in my fingers!" a website quoted 38-year-old as saying.

"I had bleeding fingers and cramps in my hands and shoulder problems. I was like, `I think I have cancer!` I went to the doctor and I had just pulled a muscle in my arm. It was a disaster. What a nerd!"
