I kept catching colds, and whenever I received cold medicine at the local clinic, I would start to feel better, but if I stopped taking the medication, I would get sick again, and the cycle would repeat. So I went to Jeju University Hospital. The ENT department at Jeju University Hospital said my symptoms were unusual. The medical staff thought it might be cancer, so I underwent tests and was diagnosed with cancer. Before going to another hospital, I received appropriate emergency treatment, which helped me get through a critical period, and now I am living very healthily. I will never forget how grateful I am when I think about that time. I recommend the ENT department at Jeju University Hospital.
