Cynthia Nixon talks about her breast cancer battle...

Cynthia Nixon says in the cuirrent issue of People magazine that she would have never have known that she had breast cancer had she not had a mammogram every year since she was 35. Something small was detected and doctors said,. "We wouldn't think anything of it except it wasn't there last year." If they didn't have the previous year's to compare it to, they might have missed it.

Still, the "Sex and the City" star was not worried: "The doctors said, 'The chances of this turning into anything really frightening are quite small.' And my mother had been disagnosed almost 30 years before and she's perfectly healthy."

But her girlfriend, Christine Marinoni, was very scared: "Christine was the one with the tears. To her, cancer sounded like, 'Oh! She's gonna die!' What turned her around was calling my surgeon. He talked to her about statistics and said, 'Don't worry, this is totally treatable.' I even had my kids (Samantha, 11 and Charles, 5) go in and speak to him. I told them, 'This is what grandma had. It's gonna be fine.'"
