Britain's Princess of Wales says that her cancer is in remission following a visit to the hospital where she received treatment

Catherine, Princess of Wales, said on Tuesday that her cancer was in remission, lifting a major cloud from the British royal family, which had struggled with serious health concerns for both her and King Charles III. “It is a relief to now be in remission and I remain focused on recovery,” Catherine, the wife of Prince William, wrote on Instagram.

The problem is that a complete remission does not mean the cancer is gone. Even when a cancer is “cured” — defined as no evidence of cancer for five years — it may not be vanquished.
