Actor Shin Seong-il's health is at risk.
TV Chosun, "My Way" revealed that Shin Seong-il was sick from lung cancer.
Shin Seong-il refused to have cameras rolling after he had a meeting with his doctor.
The doctor told the camera that his cancer mass was over 5 cm big.
Further tests will reveal the treatment he needs. Third stage cancer shows less than 20% chance of survival, but treatments might increase this chance to 30% or 40% although that is just a mere guess.
