Sharon Osbourne - Ozzy Experiment Sparked Sharon Osbourne's Breast Cancer Drama

Sharon Osbourne has spoken out about her double mastectomy drama a day after U.K. publication Hello! announced the news in a teaser for the Tv personality's big reveal.

Ozzy Osbourne's wife, who battled colon cancer in the early 2000s, underwent the preventive surgery over fears she could develop breast cancer.

She kept the drama to herself but opened up to Hello! in the upcoming issue - and on Monday (05Nov12) she talked about her decision during the opening segment of her U.S. chat show The Talk.

She revealed she first discovered she had the breast cancer gene as part of a medical experiment on her reformed wildman husband.

Sharon recalled, "They (researchers) wanted to know why my husband had lived so long - seriously.

"He has nothing. The only thing they found out is he's allergic to coffee... and alcohol... I come back with a whole shopping list... and I had the breast cancer gene and, of course, we know I had the colon cancer gene and they're very similar genes.

"I went in and I had my breast implants removed because one of them had burst... and one breast was different than the other... so my doctor said, 'Why don't we just do it all at once, and save ourselves any worry?' And I said, 'Put it there, we're gonna do it!'

"It was a decision that I made myself. I wasn't diagnosed with breast cancer, but I had the gene."

Osbourne revealed she underwent the mastectomy and reconstructive surgery earlier this year (12), but didn't want to make a fuss at the time: "I didn't wanna make a (big) deal about it then because it's like why worry people and make a fuss unnecessarily.

"I'm in a very privileged position in that I can have the best medical attention and so my surgeon, she's an amazing breast cancer specialist, reconstructed my breasts. I was very lucky."
