Sharon Osbourne has revealed she had a preventive double mastectomy upon learning she carries a gene associated with an increased risk of breast cancer.

"As soon as I found out I had the breast cancer gene, I thought: 'The odds are not in my favor,' " "The Talk" co-host and former "America's Got Talent" judge told Britain's Hello! magazine in its new issue. "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."

Osbourne had the procedure done last summer, her rep told People magazine.

Osbourne, 60, had surgery for colon cancer after being diagnosed in 2002, and chronicled her recovery on the second season of her MTV reality show "The Osbournes." In 2004, she established the Sharon Osbourne Colon Cancer Program at Cedars-Sinai Medical Center in Los Angeles.

The double mastectomy "wasn't a big decision; it was a no-brainer," said Osbourne, wife of heavy-metal musician Ozzy Osbourne. "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," the 6-month-old daughter of son Jack Osbourne and his new wife Lisa Stelly.

"I didn't even think of my breasts in a nostalgic way," she added. "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."
