SEOUL (Korea Herald/Asia News Network) - K-drama star Kim Woo Bin was diagnosed with nasopharyngeal cancer, his agency said on Wednesday (May 24).

"Kim Woo Bin wasn't feeling good and recently visited a doctor. We found out that he has nasopharyngeal cancer," Sidus HQ said in a statement. "He started receiving drug treatment and radiation therapy. Please cheer for and support him."

The agency also said the 27-year-old star of the dramas The Heirs (2013) and Vampire Idol (2011) would focus on having treatment for a while.
