Her Royal Highness Princess Chulabhorn has been advised to rest and recuperate further at Vichaiyut Hospital after a successful operation to remove a tumour from her neck, the Royal Household Bureau says.
In its third statement on the Princess's condition, the bureau said she remained very weak, and doctors therefore had recommended that she put off royal activities for a while longer.
The princess underwent a biopsy on May 20 at the hospital after a polyp was found in her neck.
In a statement on May 28, doctors said Her Highness had a high fever at times and was still very weak. They advised her to put all activities on hold and rest so that she could recover quickly.
