Sharon Osbourne recently revealed that she underwent a double mastectomy after she discovered she carries the gene that makes her predisposed to developing breast cancer.
The 60-year-old TV personality, who is also a survivor of colon cancer, told Hello! magazine that the decision was a "no brainer."
"I didn't want to live the rest of my life with that shadow hanging over me," she said. "I want to be around for a long time and be a grandmother to Pearl."
Her son Jack and then-fiance Lisa welcomed their baby, Osbourne's first grandchild, in April. Two weeks after the birth, Jack was diagnosed with multiple sclerosis.
People magazine quoted her family's rep as saying Osbourne's 13-hour double mastectomy took place last summer.
The procedure is one of several preventative treatments recommended for people who test positive for a harmful mutation of a gene that make them predisposed to having breast cancer. A mastectomy reduces the risk of developing it. Depending on the age and health of the patient, doctors may also opt to increase screenings and prescribe medications.
There is an increased breast cancer risk among women who gave birth to their first child after age 30 and among those who have battled other types of cancer. Osbourne was almost 31 when she and her rocker husband Ozzy welcomed Aimee, their first child together. In 2002, Osbourne revealed that she had beaten colon cancer.
She had already undergone another operation on her chest - in 2011, she had her breast implants removed after one of them leaked into her stomach.
Osbourne told Hello! that she does not plan on getting more cosmetic surgery, saying: "Sometimes I'll see a photo and I'll think, 'My face looks plastic'; it can look so unnatural from certain angles. Now I am definitely, definitely done. You can't buy your youth back, no matter how much money you've got I won't be going under the knife again."
