Hi I'm 17 years old and about 2 months ago I noticed a lump on the back of my head. I didn't pay too much attention to it until I started to google about it. The things that came up etc tumours, cancers osteomas just made me worry. I went to my doctors and she said it was nothing to worry about and that it happens since I'm 17 and my skull is changing. The lump feels like a bone literally and you can notice it. I'm still worried about it. I generally don't have symptoms. And it is painless to the touch. So I was wondering to get some advice to put my mind at rest.
