CNN anchor Sara Sidner reveals stage 3 breast cancer diagnosis: "I am still madly in love with this life"

CNN anchor Sara Sidner shared on Monday that she is currently undergoing treatment for stage 3 breast cancer.

Sidner, 51, announced her diagnosis during an emotional segment of "CNN News Central," which she co-hosts. Sidner told viewers she is in her second month of chemotherapy and will undergo radiation and a double mastectomy. 

"I have never been sick a day of my life. I don't smoke, I rarely drink," Sidner said. "Breast cancer does not run in my family. And yet, here I am with stage 3 breast cancer. It is hard to say out loud."
