Tammy, many years ago -- like about 40 -- the son of a friend of my Mum's had a tumour in his femur (thigh bone). He was 11 or 12 at the time. He had a couple of surgeries, and I'm not sure what other treatments. But it was successful and he's fine today, all limbs intact. That was 40 years ago, and there have been advances in treatments. To be sure, you don't treat this lightly, but please don't fight the shadows. And please don't do any more searching on the Internet for now -- at least until you do know what you are up against. Soon you'll have real information, a proper diagnosis, and then you'll know what you're dealing with. Until then, hug lots, pray lots, laugh lots. We'll be doing the same all over the world, and it will be fine.
No, you're not going to snap your fingers and it will all be behind you, but you will have the strength, and we'll be here with you.
