Neuroendocrine neoplasms

Neuroendocrine neoplasms (NENs) are a diverse group of tumors that develop from neuroendocrine cells, which are specialized cells found in various organs like the digestive system and lungs. These tumors can be slow-growing or aggressive and may produce hormones that cause symptoms like flushing or diarrhea. Because they can vary widely in behavior and location, diagnosis and treatment depend on the tumor's specific type, size, and spread. Advances in understanding these neoplasms have improved management, often involving surgery, targeted therapies, or hormone treatments to control growth and symptoms.
