Kate, the Princess of Wales, was diagnosed with cancer and is undergoing chemotherapy, she said in a video message released Friday, two months after she underwent "major" abdominal surgery. 

The type of cancer has not been disclosed. According to Kensington Palace, Kate started a course of preventative chemotherapy in late February. 

”In January, I underwent major abdominal surgery in London and at the time, it was thought that my condition was non-cancerous. The surgery was successful. However, tests after the operation found cancer had been present. My medical team therefore advised that I should undergo a course of preventative chemotherapy and I am now in the early stages of that treatment.” 

Catherine, is the Princess of Wales, and a member of the British royal family. She is married to William, Prince of Wales, the heir apparent to the British throne. 

The announcement sparked an outpouring of support and comes as Kate's father-in-law, King Charles III, also undergoes cancer treatment.
