Hi There,
The chance of something being cancer will be age dependent (the older one is, the higher likelihood of cancer)
and other risk
factorsFactor ix complex (personal history of cancer, family history of cancer)
I would say that if you are uncomfortable, you should have this ovary with the cysts removed. They are most likely benign. A cyst means fluid with a skin around it like a blister. Blood flow means that it is part of the ovary as opposed to being an adhesion with some fluid in it.
take care
