King Norodom Sihanouk has undergone chemotherapy for cancer of the prostate which

was discovered several months ago.

In a message from China, where he is undergoing treatment, the King said his doctors

had removed a cancerous tumor but more treatment was needed to keep it from resurfacing

in another part of his body.

"The chemotherapy is difficult treatment and requires many months to kill the

cancer," the 70-year-old monarch said. "The treatment by chemotherapy will

make me more exhausted and...will make me vomit and lose my hair."

If chemotherapy is not effective, the King said, he would have to undergo radiotherapy

and take traditional Chinese medicine. - AP
