Shannen Doherty is also battling cancer. The actress has been suffering from the insidious disease for years. She was initially diagnosed with breast cancer, which she seemed to have beaten. But a few years later, the disease returned and even metastasized to her brain. Shannen made a post on Instagram expressing her support for Kate: "Princess Kate, I admire your strength through the endless onslaught you've been under while going through cancer." Shannen also takes the opportunity to clarify how important privacy is even for people in the public eye: "The onslaught of conspiracy theories, ownership, and plain, morbid curiosity forced this person to explain herself before she had come to terms with it and explained to her children,” she continued. “I pray this is a learning moment for us all to respect, privacy or others, regardless of being in the public eye."
