So, I think that your doctor would tell you if cancer was a concern but
cysts are different than cancer
tumors.
And if he is worried, he/she would do a cancer marker test, CA125 test. It's a blood test and if you are over a certain number, there is ovarian cancer present.
My mother in law died of ovarian cancer. That is the other thing, the statistics are on your side. Young women rarely have this type of cancer.
