This echogenic area may or may not be cancerous. You will need an MRI
of the Abdomen and Pelvis to characterize this lesion. Blood tests like CA 125 will be needed for assessment. If there is no solid area in the cyst
and Ca 125 is normal then the chances of cancer are small. Sometimes final diagnosis may not be clear even after an MRI. So you may need Operation and Frozen biopsy
to confirm or rule out cancer.
