Ovarian cycst found on ct i get a ct every 6 months to month monitor for pancreatic cancer how worried should i be that it has spread to ovary ?

Ultrasound: If they saw an ovarian cyst, it is very unlikely to be cancer - most likely it is just that- a cyst. However, the best way to evaluate the ovaries is to have a pelvic ultrasound. I would recommend seeing a gynecologist and getting a pelvis ultrasound. That can give you more information about what the cyst on the ovary looks like and whether it has any concerning features.
