Sung In Kyu, �former member of disbanded DSP Entertainment group A'st1, recently revealed that he was diagnosed with thymus cancer. �Thymus cancer occurs from�tumors�originating from the thymic epithelial cells. �Symptoms include�difficulty swallowing, a strong cough, and/or chest pain. �Typically,�surgery�is required to remove the tumor and recover from the disease. On October 31st, he posted on his mini homepage,

I will confess. I don't like people calling a person sick. On April, 2011, severe chest pains began to start. I kept thinking it wasn't anything until May. I felt that the condition was serious and went to the hospital to take CT scans. They told me that there was a lump discovered in my chest and it continued to the veins on my neck I didn't think it would be serious, I was hospitalized and I had a biopsy examination and waited a few days. Before the results came out, they said it was one of the three things.. I found out that they weren't good things It was a tumor...and it was infectious...in one word, I didn't think it became a thymus cancer tumor as it went up to the veins on my neck, making it difficult to breathe. If I had waited any longer, it would have become something unimaginable Since last May, I had 6 chemotherapy sessions. Since surgery was dangerous, they said I couldn't do it... I thought I was healthy, but a sickness found me without a reason I'm really receiving a lot of stress and from the second half of 2009, I had a difficult time. I had a lot of concerns on everything...I have a rare disease, thymus gland cancer, 2nd stage. They said that it wasn't because something (ie one of his body parts)�wasn't good. It seems the cause is stress, and they said it's good to not sing the songs I like in the hospital for now. �Now when I sing, even though it's hard to breathe, I won't give up my dream...I'll show you As I receive treatment, I will deliver good news. It seems I'm telling this all now and I thank all those who have waited for me and had me in their thoughts I will make sure to return it and I will see you on the stage. I love you.
