Serous Cystic Neoplasm (SCN) is a type of tumor that primarily occurs in the pancreas. These tumors are usually benign, meaning they are not cancerous, and are characterized by the presence of fluid-filled cysts. SCNs are more common in women and often develop in middle-aged individuals. Diagnosis typically involves imaging techniques like CT scans or MRI, which help visualize the cysts. Treatment may include monitoring the tumor or surgical removal if it causes symptoms or has the potential to become malignant. Overall, SCNs have a favorable prognosis when managed appropriately.
