Their has been more death's from cancer, than survivors.
Is this a fact or are you just saying? Because I'm sure there are tons of cancer survivors that get treated because they catch it in the early stages. If anything, you should go to the doctor to get it checked out so if anything (God forbid) you can treat it as early on as you can.

But don't be afraid to check it out.. my sister has a mole on her back that she gets checked.. it's pretty big but non cancerous. I'm sure it's alright. Maybe you can get it removed?

Don't think you're weird for freaking out over your health. Oh my gosh, I'm the biggest worry-wart about those things. If I find anything on myself, I totally freak out. Once I panicked because I had these little brown spots on my wrist. I finally asked the doctor and he said they were just light beauty marks, lol.

I hope everything is alright but honestly, don't worry about it and get it checked out. It can only help you.
