Mucinous Cystic Neoplasm (MCN) is a type of tumor that primarily occurs in the pancreas. It is characterized by the presence of cysts filled with a thick, mucous fluid. MCNs are more common in women and can vary in size. They may be benign or have the potential to become cancerous, making early detection important. Diagnosis typically involves imaging techniques like CT scans or MRI, and sometimes a biopsy is performed. Treatment often requires surgical removal of the tumor, especially if there are signs of malignancy. Regular follow-up is essential to monitor for any changes.
