Ozzy Osbourne's wife/manager Sharon Osbourne has revealed that she underwent a preventive double mastectomy over fears she could develop breast cancer.The 60-year-old, whose son Jack became a first-time dad to daughter Pearl earlier this year, told Hello! magazine that doctors told her she had a genetic mutation which raised her chances of developing breast cancer, which convinced her to have the procedure done. "As soon as I found out I had the breast cancer gene, I thought: 'The odds are not in my favour'. I've had cancer before and I didn't want to live under that cloud: I decided to just take everything off, and had a double mastectomy," she said. She added, "For me, it wasn't a big decision, it was a no-brainer. I didn't want to live the rest of my life with that shadow hanging over me. I want to be around for a long time and be a grandmother to Pearl. "I didn't even think of my breasts in a nostalgic way, I just wanted to be able to live my life without that fear all the time. It's not 'pity me', it's a decision I made that's got rid of this weight that I was carrying around."
