The 61-year-old former model revealed last month (Mar16) that she was found to have early stage ductal carcinoma in situ (DCIS) - a form of the disease that starts in the milk ducts - after her doctor discovered a lump in her right breast during a routine examination.

During an appearance on The Doctors on Wednesday (06Apr16), Janice opened up about her battle with disease, admitting she has had a surprisingly emotional reaction to the diagnosis.

"It's shocking, everything hit me at once," she said on the show. "My mother died of cancer, so I know how bad I felt when I heard about my mother. My son broke down. Honestly I haven't cried in about 30 years, and just lately I'm tearful because I felt fear for the first time. And I don't get scared. I kind of lost it."

Former America's Next Top Model judge Janice is now planning on having an operation to remove a one-inch area of skin around the lump removed from the breast. Doctors will also check Janice's lymph nodes for any signs of the disease, as well as having radiation on the affected cells and taking medication, most probably for the rest of her life

While Janice has always been strong, she admits she has been struggling to cope since being told the devastating news.

"I use to obsess over image, I'm the world's first supermodel, I've been in front of cameras. I will never keep quiet when something is bothering me. I'm a fighter," she said.

"I'm not the type of woman to fall apart but it's nothing to downplay."

Janice is being supported by her family and her fiance Dr. Robert 'Rocky' Gerner as she fights the illness. She is determined that "cancer does not define me", and adds: "I want to see my daughter walk down the aisle and I want grandchildren, and I want to get married with Rocky, my fiancé, who's a doctor."
