Serous cysts are fluid-filled sacs that can develop in various organs, most commonly in the ovaries or pancreas. They are typically benign, meaning they are not cancerous, and often do not cause any symptoms. These cysts are usually discovered incidentally during imaging tests, such as ultrasound or CT scans. While serous cysts are generally harmless, monitoring may be recommended to ensure they do not grow or change. In some cases, if a cyst becomes large or symptomatic, medical intervention may be necessary. Regular check-ups can help manage any potential concerns related to these cysts.
