LONDON (AP) — Kate, Princess of Wales, announced Monday that she has completed chemotherapy treatment for cancer and plans to return to some public duties.

It comes after a difficult few months for the royals in which both 42-year-old Kate and King Charles III were treated for cancer. Charles, 75, has been easing back into public engagements since April following a three-month break to focus on his treatment and recuperation after he was diagnosed with an undisclosed type of cancer.

Kate has made only two public appearances since announcing her own diagnosis in March. She said “the last nine months have been incredibly tough for us as a family," but that she had “a renewed sense of hope and appreciation of life.”

Here’s a timeline of recent events in the royal family:
