Celebrities who have battled breast cancer

10 of 15: Cynthia Nixon was diagnosed with breast cancer in October 2006, several months after she won her first Tony for her role as Becca in the Broadway play 'Rabbit Hole. At the time, was starring in the off-Broadway play 'The Prime of Miss Jean Brodie.'

'I go for my completely routine mammogram and then I get a call from my gynecologist,' the 'Sex and the City' actress told the ABC program 'Nightline' in April 2008. 'And she says, 'Well, I have some - it's not such great news, but here it is, but it's very small and we're just going to get in there and take it right out, right away, and then you'll probably have radiation.''

The actress scheduled her surgery for a Sunday 'so that she wouldn't miss even a single performance of her play,' ABC said.

'My girlfriend was very scared. She was the one doing the eating. She was in a panic. She was just trying to calm herself down any way she could. And, actually, we made a big point of talking to my kids about it.'

Nixon has a son and daughter with her ex-boyfriend of 15 years. She and her girlfriend, Christine Marinoni, began dating in 2003 and got engaged in 2009.

Nixon told The Daily Beast in an interview published on Jan. 24, 2011 that she underwent a 'very small' lumpectomy and radiation treatments for six and a half weeks and has taken the anti-estrogen drug Tamoxifen for the past five years.

'We'll see if they take me off of it this spring,' she told the website.

In 2011, Nixon appeared on the Showtime series 'The Big C,' playing the friend of Laura Linney's main character, Cathy, a woman who battles skin cancer. In January 2012, Nixon played a cancer patient in the Broadway play 'Wit' and shaved her head for the role.
