Osteoma of skull is a benign tumor growing on flat bone. Most of them stop growing with the end of adolescence, and almost no malignant change will occur. Be careful not to touch it from time to time every day if it doesn't need to be treated and it doesn't affect the appearance. Sometimes long-term stimulation will make it grow up. Feeling affects aesthetics or has clinical symptoms that can be operated.

I suggest you go to the Department of Bone Oncology in beijing jishuitan hospital to see Professor Zhang Qing. My father-in-law is also a bone tumor. That's where I saw it. It is the authority of bone tumor in China.
