Hello,

Based on the description of the cysts, I would not have concerns that they they represent cancerous masses. Usually, if there were concerning features of the cysts (septation, vascularity, irregular calcification) they would have commented on the report and suggested a follow-up. Subcentimeter cysts without other descriptors does not sound concerning. But for added peace of mind, you could do a simple abdominal ultrasound to verify.
