black spots

My uncle had a black spot the size of a 500 won coin on his head and a 100 won spot on his back, so he went to the dermatologist. He recommended a test at a university hospital. The director said it looked like a wart, but he didn't go. About 2-3 years had passed, but last year I was worried, so I took him to Dong-A University Hospital. They told me to make an appointment in June, but when I went, they said they'd see him in November of next year. I was shocked because they didn't have a specialist, so I went to Maryknoll General Hospital. The director looked at it and was a little worried because it was corroded on one side. The test results came back as a blessing. I guess my ancestors helped me because I worried so much.
