Patient: 15 years old, osteochondroma. I went to the hospital at the beginning of last year to check only the size of a bean grain, but in May it was as big as an egg and grew quickly. What should I do? Do I still have to do surgery? Can it be cured? Doctor: If the tumor grows so fast as you said, it may not necessarily be an osteochondroma, but we need to see the patient and the film to know the details.
