Following weeks of speculation about her health status, Princess Kate opened up Friday about her recent cancer diagnosis and the impact it's had on her family life.

"I wanted to take the opportunity to thank you personally for all the wonderful messages of support and for your understanding whilst I've been recovering from surgery," said Kate in a video released by Kensington Palace. "It has been an incredibly tough couple of months for our entire family. But I've had a fantastic medical team who've taken great care of me, for which I'm so grateful.

"In January, I underwent major abdominal surgery in London. And at the time, it was thought that my condition was non-cancerous," she continued. "The surgery was successful. However, tests after the operation found cancer had been present."

Kate said it has "taken time" to explain her diagnosis to her and William's children — Prince George, 10, Princess Charlotte, 8, and Prince Louis, 5 — appropriately and "to reassure them that I'm going to be OK."

Kate also shared words of encouragement for others who have been diagnosed with cancer. "Please do not lose faith or hope. You are not alone," she said.
