The wife of Ozzy Osbourne revealed in November last year, "For me it was a no-brainer. I want to be around for a long time and be a grandmother to Pearl (her son Jack's baby daughter)."
In typical forthright fashion, Sharon elected to "just take everything off".
"It's not 'pity me'," she said. "It's a decision I made that's got rid of this weight I was carrying around. I didn't want to live the rest of my life with that shadow hanging over me."
E! host Giuliana Rancic was diagnosed with breast cancer in 2011 and underwent a double mastectomy. She and her husband Bill has been vocal about their failed IVF treatments and heartbreaking miscarriage. But they have since gone on to have a baby via surrogate.
TV star Michelle Heaton underwent a double mastectomy late last year as prevention against breast cancer.
The 33-year-old mum of one who found fame with band Liberty X made the tough decision to have both breasts removed as her chances of developing breast cancer were at 80pc.
The former You’re A Star judge, who is married to Dubliner Hugh Hanley revealed how she decided to get the traumatic operation over before Christmas – so she could “start living” again.
Michelle had discovered that she had the BRCA2 cancer gene and decided the chances were too high to take.
She also has a 30pc risk of developing ovarian cancer and has decided to have her ovaries removed, but only after she has had another child.
The Newcastle mum appeared on the Late Late Show after making her decision and broke down in tears as she told Ryan Tubridy how the shocking news had effected her life.
American author Allison Gilbert also underwent the procedure after testing positive for the BRCA gene, "My children would tell you I don't bake cupcakes for their birthday parties, but I'd readily cut off my breasts for them -- and I did."
Statistics show that a woman who inherits a mutation in the so-called breast cancer genes', including BRCA1 and BRCA2, is five times more likely to develop breast cancer than a woman who does not have the mutation. Also, the risk of ovarian cancer soars from 1.4pc in women with healthy genes to between 15 and 40pc in those with the mutated gene.
