Princess of Wales says she is undergoing cancer treatment

The Princess of Wales says she is in the early stages of treatment after cancer was found in tests.

In a video statement, Catherine says it was a "huge shock" after an "incredibly tough couple of months".

But she sent a positive message, saying: "I am well and getting stronger every day."

Details of the cancer have not been disclosed, but Kensington Palace says it is confident the princess will make a full recovery.

The princess's statement explains that when she had abdominal surgery in January, it was not known that there was any cancer.
