Cynthia Nixon may be having a great time shooting the Sex and the City movie sequel, but she hasn't forgotten a side of life that's no laughing matter.
Nixon, 43, has teamed up with Stand Up to Cancer for a new public service campaign to educate cancer patients and their supporters about the risk of infection during treatment.
Nixon, a cancer survivor herself, is featured in print ads with the tagline, "Some things in life you can't control. Lowering your risk of infection during cancer treatment, you can."
The campaign, which also includes a series featuring Nurse Jackie star and fellow cancer survivor Edie Falco, will begin running later this month. The ads along with television spots direct people to manageyourtreatment.com for more information.
Nixon revealed in 2008 that she battled breast cancer about two years earlier. She underwent a lumpectomy and six and a half weeks of radiation.
"I didn't want to make it public while I was going through it," Nixon said in an interview with Good Morning America. "I didn't want the paparazzi at the hospital, that kind of thing."
She has since become a very visible and vocal cancer advocate.
