What are the symptoms of ovarian cancer vs. ovarian cysts?

I had an ovarian cyst about two years ago. My sister has PCOS and there’s a good chance that I have it as well. I’m more concerned that I have a possible tumor though. I looked up the symptoms for ovarian cancer and I have almost all of them except for maybe one or two. I’m really scared. I’m only 17 and I have no idea how to approach my parents about it. If I do have something wrong with me though, I don’t want to wait until it’s too late to try and get help. I also have symptoms that could possibly just be another cyst, although I did just get my period so I don’t think that it could be a cyst. It could even be uterine prolapse, but those symptoms aren’t the same as the gassy, abdominal pain and back pain I usually have particulary the week before and the week after my period. I also have a lot of underarm perspiration. Could this be another sign? Mostly I’m just scared that it might be to late and though I’m a strong Christian and I understand that there is a reason for everything.

It is usually not best to diagnose yourself without about 10 years of medical education and specialization – and even then it isn’t a good idea. Make an appointment with your ob/gyn or family practitioner if you are worried about it.
