Yoo Ah In's bone tumor not malignant but benign

His label toldDongA.com, "It's true he has a bone tumor, but it's benign, not malignant. There won't be any effect on his everyday life. We just have to watch how it is. We never said he was sick, so we don't know where that started. His health is fine. It's not so serious that he's sick or that he needs to get treatment. We hope there aren't any misunderstanding through exaggerations. We're just burdened that family or friends would see and get worried."
