Japanese Emperor Naruhito has been found to have an enlarged prostate but there is no cause for concern, the Imperial Household Agency said Thursday.
The 62-year-old underwent a health examination on Sunday after the agency announced in early October that his prostate-specific antigen level, a tumor marker, was slightly higher than normal and "showing a slightly worrying movement."
It will be decided whether the emperor will need treatment following a prostate tissue examination scheduled later this month, the agency said.
"I will continue to pay close attention to (the emperor's) health," Yasuhiko Nishimura, head of the agency, said at a regular press conference.
The emperor has no symptoms and is scheduled to visit Hyogo Prefecture for an official event this weekend.
In 2007, the emperor had endoscopic surgery to remove a benign duodenal polyp, but he has not had any other medical problems.
