Cure Cancer

Well my question is really for someone out there who had been diagnosed with cervical or uterine cancer. I just wanted to know what made you go to the dr in the first place. What were your symptoms?

I’ve been told I should most likely get checked earlier than most because my mother had precancerous cells in her cervix, my grandfather died of some kind cancer, and my great grandmother died of breast cancer. I’m 15, and how early do people mean by early?
Both of my parents also have high blood pressure. My mom said not to worry about that until my twenties or thirties, but I’d like to get some second opinions on how early checks like these should start.

I just found out that i may have skin cancer, if I don’t get any treatment for it what will happen?

I have always read stories about people loosing weight when they have cancer. I know there are certain kinds that can make people weigh less than 100 lbs, but what causes the weight lose? Is it the chemo and medicine, or if you go untreated, will the cancer cause this on it’s own?

Also any other statistics about breat cancer are a great help. I need this info for a school project. Thanks!
