The 64-year-old actress, an Oscar winner for her role in the 1991 thriller "Misery," explained to the celebrity magazine that she had been diagnosed with breast cancer several weeks ago.
"After much consideration, I underwent a double mastectomy," she reveals. "Luckily, I don't have to undergo radiation or chemo. My family calls me Kat because I always land on my feet, and thankfully this is no exception."
Post-surgery, Bates remains hopeful that she will get well.
"My doctors have assured me I'm going to be around for a long time," she says. "I'm looking forward to getting back to work doing what I love to do."
