Charles and Catherine's cancer diagnoses: key dates

King Charles III and his daughter-in-law Catherine, Princess of Wales, have been fighting cancer this year, but both have now reported good news with their health battles.

Charles has been increasingly visible at events while Kate, as she is widely known, said Monday she hoped to undertake more public engagements in the coming months after completing chemotherapy treatment.

Kensington Palace announces that Catherine, the 42-year-old wife of Charles's elder son and heir Prince William, is facing up to two weeks in hospital after successful abdominal surgery.

Hours earlier, Kensington Palace had announced that Catherine had also returned home.

Charles is seen for the first time in public since his diagnosis, waving at crowds from a car.

William pulls out of attending a memorial service for his late godfather, King Constantine II of Greece, citing a "personal matter".

Kensington Palace declines to elaborate but says Catherine continues to be "doing well".

British media later report that this is likely the day Catherine found out about her cancer.

But it sparks a storm after major news agencies including AFP withdraw the photo saying it had been manipulated.

Catherine later apologises for making alterations to the Mother's Day image.

In July, she attends the Wimbledon men's tennis final, receiving cheers as she walked onto Centre Court to present the trophy to Carlos Alcaraz.

The princess reveals in a highly personal narrated video message she has finished chemotherapy treatment and that "doing what I can to stay cancer-free is now my focus".

Voiced over montages of Kate, William and their three children enjoying idyllic countryside, she adds her "path to healing and full recovery is long" and that she "must continue to take each day as it comes".

"I am however looking forward to being back at work and undertaking a few more public engagements in the coming months when I can," Kate saus.
