Unless you have a BRCA mutation you have a less than 1% of ovarian cancer. Ovarian cysts can cause problems. I would get a vaginal ultrasound to be safe. The cancers you worry about in the 50's age group or earlier are Ovarian, Triple Negative Breast cancer, and prostate cancer. Later breast or prostate cancer are less likely with BRCA. Non BRCA breast cancer will not be triple negative usually. I am BRCA 1 positive.
