TVXQ's Yunho confessed that he almost gave up becoming a singer because of some medical issues that he had.

Yunho and Changmin attempted a relay lecture while filming for KBS 2TV's 'Do Dream'. Yunho titled his lecture 'Dreams do not abandon you', and started by saying "My maternal family comes from a singing background. I inherited those skills and received awards at vocal competitions." However, he became struck with an illness that trapped hormones in his tonsils, and grew a bump on his neck and vocal cords. The bump prevented him not only from singing, but properly talking in everyday life.

However, Yunho ignored his symptoms and worked through blood and tears to debut as a member of TVXQ. But even after his debut, he faced problems. He revealed, "After our debut, I was preparing for our concert. But the area on my neck where I got surgery became problematic again. I got infections in my neck, mouth, and nose, a total of 40-50 places. The company tried to prevent me from doing it, but I wanted to do my best on stage. There was a great chance that my neck could become worse, but I got on stage after numbing it."

The full episode of 'Do Dream' and Yunho's lecture will air on October 6th.
