Roll out the royal red carpet.

King Charles III is returning to his public duties after taking a step back from treatment for an undisclosed form of cancer.

The British monarch will visit a cancer treatment center with his wife, Queen Camilla, on Tuesday, Buckingham Palace announced in a news release. There, the couple "will meet medical specialists and patients."

"As the first anniversary of The Coronation approaches, Their Majesties remain deeply grateful for the many kindnesses and good wishes they have received from around the world throughout the joys and challenges of the past year," the palace said.

Charles will continue treatment for an undetermined amount of time, but according to the palace, "doctors are sufficiently pleased with the progress made so far that The King is now able to resume a number of public-facing duties."

Despite not having a clear timeline on when Charles can conclude treatment, the palace said his medical team is "very encouraged by the progress made so far and remain positive" about his recovery.

Will Charles return to a full schedule?

Charles' treatment center will "be the first in a number of external engagements" coming up, although his schedule won't immediately return to what it was before his diagnosis.

Outings "will remain subject to doctors' advice," but "it will not be a fullsummer program," the palace said.

Whether the pace of his duties increases is a decision for his medical team, and certain events will be "adapted where necessary to minimize any risks" to the king, the palace said.

Charles' first major event includes a state visit from Japan

Among one of the bigger anticipated events during Charles' recovery is a state visit from Japan's Emperor Naruhito and Empress Masako in June.

The Japanese royalty will be hosted at Buckingham Palace nearly four years after their planned visit in 2020 was postponed because of the COVID-19 pandemic.

Buckingham Palace announced Charles' cancer diagnosis in February

Buckingham Palace confirmed on Feb. 5 that Charles was diagnosed with "a form of cancer." Before the announcement he was hospitalized and underwent a procedure for benign prostate enlargement in January, and the cancer was identified via diagnostic tests after a "separate issue of concern was noted."

"His Majesty has today commenced a schedule of regular treatments, during which time he has been advised by doctors to postpone public-facing duties," the palace said. "Throughout this period, His Majesty will continue to undertake State business and official paperwork as usual."

His daughter-in-law Princess Kate has also been diagnosed with cancer and has been taking a break from public duties.

In a video released by Kensington Palace last month, Kate, 42, called her diagnosis a "huge shock" for her family, adding that she and Prince William have done "everything we can to process and manage this privately for the sake of our young family."

Kate said it has "taken time" to explain her diagnosis to her and William's children and "to reassure them that I'm going to be OK."

The palace first announced in January that Kate had been admitted to the hospital for planned abdominal surgery.

In a statement at the time, the palace said Kate's surgery was successful but that "based on the current medical advice, she is unlikely to return to public duties until after Easter."
