Kate Middleton says she was diagnosed with cancer, is undergoing chemotherapy

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

The type of cancer has not been disclosed. She started chemotherapy in late February.

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