One reporter stated Kim Woo Bin had to stop filming due to his condition, reporting, "Kim Woo Bin's neck suddenly started to become inflamed, and his nose started bleeding. After going to the doctor, he was diagnosed with nasopharyngeal cancer."
'Heard It Through the Grapevine' host Lee Joon Seok explained, "Nasopharyngeal cancer is a type of cancer that is caused by tumors from the back of the nose to the rooftop of your mouth. However, if the cancer cells travel towards the brain, a cranial nerve paralysis can occur. It's a rare and serious disease that happens to 1 in 100,000 people."
Another reporter mentioned, "Kim Woo Bin is resting, so he can fully concentrate on his treatment. At first, he didn't want to become a burden to the movie so he wanted to continue to film, but all the producers told him to focus on his treatment."
Hopefully, Kim Woo Bin recovers soon.
