Just noticed it yesterday. I thought it was just part of skull but it seems quite prominent and only on one side-round bony lump maybe a bit less than an inch in diametr what can it be? I've never heard of cancer on tge head so trying to not freak out. Can it be a perfectly round bone that suddenly grown or something? I don't think it's a lymph node cos it doesn't move and feels like a bone just a raised round one... I don't want to go to the doc I've been there recently with a different thing...
