Neuroendocrine tumors (NETs)

Neuroendocrine tumors (NETs) are abnormal growths that develop from specialized cells called neuroendocrine cells, which produce hormones regulating various body functions. These tumors can occur anywhere in the body but are most common in the gastrointestinal tract and lungs. NETs can be slow-growing or more aggressive, and they may produce excess hormones, causing symptoms like hormone-related syndromes. Diagnosis often involves imaging and biopsies, and treatment can include surgery, medication, or targeted therapies. Because they vary widely, management depends on the tumor’s location, type, and behavior.
