Christina Applegate, who was diagnosed with breast cancer a month ago, says she’s had a double mastectomy and now has a clean bill of health. And while her positive outlook seen during the interview is empowering, she should also be educating the public that she is still at risk of relapsing — even after her mastectomy.

"I’m clear. Absolutely 100 percent clear and clean," the 36-year-old "Samantha Who?" actress told ABC’s "Good Morning America" in an interview that aired today.

Remembered as the "Married With Children" child star, Applegate has become the latest face of a young breast cancer survivor. She’s becoming an example for young females to start considering themselves at risk for breast cancer, and to not think that the disease is limited to older women.

To be sure her cancer would be completely removed and that there would be a reduced chance of relapse, the actress told ABC she opted to have both of her breasts removed in an operation known as a prophylactic double mastectomy — even though cancerous lumps were only found in one breast. While the healthy glow has returned to her face and she says she is 100 percent cancer-free, she should also be speaking about her chance of relapse.

The U.S. National Library of Medicine and National Institute of Health note that prophylactic mastectomy greatly reduces the risk, but does not eliminate the risk of breast cancer.

Applegate’s mother also battled and survived breast cancer. According to the National Cancer Institute, a woman’s risk of breast cancer is higher if her mother, sister or daughter had breast cancer. Applegate said that her mother shared in her fear and fury when the MRI detected the disease. However, she also said that it was her mother, Nancy Priddy, who helped her gain the courage she needed to survive.

"She’s been sort of this quiet warrior in the back and has been a great support, and just telling me that I was going to be OK. And I knew I was going to be OK. I’ve watched her," she said in the interview.
