Tumors is such a scary word. Specially when you read so much on the news about it.How do you know if you have a tumor?

I recently was feeling my head, and noticed a lump on the right side of the top of my head. I don't know how long it has been there and it doesn't hurt, has anyone have or had this before. im kinda worried that it might be cancer or something bad. i can't sleep at night because im constatnly thinking about it and i don't know what to do cuz when you go to the doctor they usually just say "oh, its nothing" what do you think i should do.

how about you? do you have a lump on your head? tell me about it. maybe i can learn from you

if you can help us all maybe we can help each other if you can provide this information:
