The specific type of cancer has not been made public.
What is known
Buckingham Palace has said that King Charles III has “a form of cancer” discovered during treatment for an enlarged prostate, but officials have emphasized that it is not prostate cancer. Multiple reputable news outlets report that neither the palace nor the King has disclosed the exact type of cancer.
Sources close to the King have indicated that the choice to keep the exact diagnosis private is deliberate, in order not to single out one cancer type or invite speculation beyond what the palace is prepared to share. Recent updates say he has responded well to treatment and that his treatment schedule is being reduced, but still without identifying the cancer type.
