The reason for Princess Kate's surgery is still unknown, but the Imperial Household Agency confirms that she does not have cancer.

[Details remain sparse and will likely remain so regarding the health of Princess Kate, who has been hospitalized for "scheduled abdominal surgery," according to a statement released today by Kensington Palace. Princess Kate's "successful" surgery is expected to keep her in the hospital for up to two weeks, after which she will return to Adelaide Cottage in Windsor to continue her recovery. She will then return to Adelaide Cottage in Windsor to continue her recovery.

The Palace did not say what Kate was being treated for, but confirmed that she does not have cancer.

Sources told the Times that Kate is "doing well" since her surgery. The magazine also reported that Kate was not rushed to the hospital and that her symptoms did not develop over the weekend.

The London Clinic, where Kate is staying, is considered the largest private hospital in the UK and even boasts its own concierge service. Although visitation is permitted until 9:30 p.m. (visits after that time must be requested), "Princess Charlotte, Prince George, and Prince Louis are unlikely to see their mother during their stay, as the children are not permitted to see them," the Mirror reported.

The hospital specializes in robotic surgery, which allows surgeons to perform more complex and safer procedures.
