Appendiceal tumors are abnormal growths that occur in the appendix, a small pouch connected to the large intestine. These tumors can be benign (non-cancerous) or malignant (cancerous) and may cause symptoms like abdominal pain, nausea, or changes in bowel habits. Early detection is important for effective treatment. The most common type of appendiceal tumor is appendiceal carcinoid, which usually grows slowly and may not cause symptoms initially. Other types include mucinous neoplasms and adenocarcinomas. Diagnosis often involves imaging tests and sometimes surgery to remove the tumor, ensuring the best possible outcome for the patient.
