• Neuroendocrine tumors (NETs) are neoplasms that arise from cells of the endocrine (hormonal) and nervous systems. (wikipedia.org)
  • The World Health Organization (WHO) classification scheme places neuroendocrine tumors into three main categories, which emphasize the tumor grade rather than the anatomical origin: well-differentiated neuroendocrine tumors, further subdivided into tumors with benign and those with uncertain behavior well-differentiated (low grade) neuroendocrine carcinomas with low-grade malignant behavior poorly differentiated (high grade) neuroendocrine carcinomas, which are the large cell neuroendocrine and small cell carcinomas. (wikipedia.org)
