Britain's King Charles was diagnosed with cancer in February. The treatment "is moving forward in a positive direction", sources at Buckingham Palace tell Sky News.
The King's treatment will continue next year, the channel reports.
The optimistic mood is confirmed, among other things, by the King's wish to have a fully booked program of public appearances, according to the source.
Charles, 76, has been open about his cancer diagnosis in the hope that it can help others. He has, however, not revealed details about the disease or the treatment.
A cancer treatment can take over a year, notes Laura Lee, head of the support organization Maggie's.
