Sharon Stone had an instinct her previous marriage had run its course.

The Basic Instinct actress revealed that she ended her marriage because of the way her ex-husband reacted to her early 2000s decision to have a bilateral mastectomy to remove a tumor from her breast. 

“One of them was bigger than the size of my entire left breast,” Stone recalled of the tumor on the June 1 episode of David Begnaud’s The Person Who Believed in Me podcast. “And the doctor had come out to my house and said, ‘Look, we think you should have a bilateral mastectomy. This is really bad. And we usually, when they’re all the way up into here, we know before we go in that they’re cancer.’”

But the 68-year-old could not comprehend the idea of having breast cancer, telling her doctor, “’I don’t have cancer.’”

“He said, ‘You don’t get to decide that,’” she recalled. “I said, ‘I do. I do get to decide that. I’m deciding. But I am deciding that I will have a bilateral, because I’m not f–king around.’”
