CBS Anchor Norah O'Donnell on How She Found Out About Her Skin Cancer

Norah O'Donnell has opened up about her skin cancer diagnosis, saying she received the news during a regular checkup with her dermatologist. The "CBS This Morning" anchor learned in November that she had a cancerous melanoma on her upper left back after her doctor identified two irregular moles. Melanoma accounts for just one percent of all skin cancers, but it's the most deadly, according to the American Cancer Society. "Don't be afraid to go to your dermatologist," she said.
