The actress tells CNN she cares deeply about being able to "educate the public about HPV."
"In the belief that I wrote deeply about saving lives," wrote in an email to CNN. HPV can cause cervical and other cancers … It is so common that almost every person who is sexually active can get it at some point in their lifetime.
Cross 'husband, Tom Mahoney was diagnosed with throat cancer in 2009 and doctors suspect that Cross' cancer and Mahoney's came from the same type of HPV.
Cross has appeared on "One Life to Live," "Knots Landing" and "Melrose Place." She is best known for her role as Bree Van de Kamp on "Desperate Housewives" from 2004 to 2012, for which she is nominated for three Golden Globes and an Emmy.
The actress has said that her cancer was discovered as part of a routine exam by her gynecologist. Cross went through both radiation and chemotherapy and is now in remission.
Cross, who has twin daughters with Mahoney, told CNN that every day with her family is a blessing.
"And I sat at my twin daughters' graduation yesterday, I was so grateful to be alive and well and thought that if I could give that to another person it would all be worth it."
