Dear Doctor, I have a hard stop on my head by birth. From past 12-15 months that has increased a lot. Although it doesn't bother me. And also no fluid comes out of it but some sort of skin is removed when I scratch it up. I don't know what it is. After a little research, I could find it resembles with a wart as you could see in the picture attached. The length is about 3cm. Please tell me how should I take it forward for treatment. Thank you.
