1. Sheryl Crow. The 52-year-old was diagnosed with breast cancer in February 2006 and has become a huge activist for activist for early detection. ET spoke with her doctor, Dr. Kristi Funk, who explained just what could have happened to the singer if she didn’t get diagnosed when she did. “The truth is, a mammogram saved her life,” Funk revealed. “She's very vocal about that. She is the poster child for early detection.”

2. Christina Applegate. The actress was just 36 years old when she had the double mastectomy that saved her life. Six years after her surgery, she says having a daily reminder of what she’s gone through isn’t easy. “I still sometimes lose my mind six years later,” she told ET’s Brooke Anderson. “You have a daily reminder of everything that you’ve gone through.”

3. Joan Lunden. The former Good Morning America anchor was diagnosed with triple-negative breast cancer this past June and recently shed her wig for the cover of People magazine. "I could decide to do nothing, but that's certainly not my personality,” the 64-year-old told the magazine. “I was handed an opportunity to learn everything that I can about this and try to help others."

"I've just joined a family of millions of women who have gone through this," the 76-year-old told Oprah in 2013. "I thought what a journey this is going to be.

6. Suzanne Somers. The 68-year-old could not believe her diagnosis because she didn't consider herself at risk. "When I was diagnosed with cancer, I was shocked," she told Everyday Health in 2011. "I never smoked. I never drank to excess. I ate right. And I didn't abuse pharmaceuticals. I had done the work!"

7. Guiliana Rancic. The host revealed that she had been diagnosed with early-stage breast cancer in 2011. She found out she had disease after a routine mammogram before receiving another round of IVF treatment for fertility.
