"Everyone is currently expressing their concern regarding Kim Woo Bin’s condition. We are giving this statement to address those concerns. Kim Woo Bin has been extremely busy with his schedules as of late and during this period, he felt his body’s condition wasn’t good so he went to the hospital. At the hospital, he was diagnosed with Nasopharynx cancer. Luckily, it is not too late to start treatment so we want to let fans know that he is currently undergoing treatment. He will come back when he is completely healthy again so we wish everyone will wish him the best during these times.”
According to WebMD, "Nasopharyngeal cancer is a rare type of head and neck cancer. It starts in the upper part of your throat, behind the nose. This area is called the nasopharynx."
Thankfully, the cancer was discovered early so chances of Kim Woo Bin's recovery are optimistically high. Woo Bin had been getting ready to start filming his upcoming movie Wiretap this summer. However, that has been delayed until he recovers. The production team has said that they will wait for him instead of replacing him with another actor.
We wish Kim Woo Bin, his family and his fans, the best in these hard times.
