Cystic tumors are abnormal growths that contain fluid or semi-solid material within a sac-like structure. They can develop in various organs, including the ovaries, pancreas, and kidneys. While some cystic tumors are benign and pose little risk, others may be malignant and require medical attention. Diagnosis typically involves imaging techniques such as ultrasound or CT scans to determine the size and nature of the tumor. Treatment options vary based on the tumor's characteristics and may include monitoring, surgical removal, or other interventions to manage symptoms or prevent complications.
