Neuroendocrine tumors are tumors that originate from neuroendocrine cells. Benign neuroendocrine tumors can be cured by radical surgical removal. Malignant neuroendocrine tumors generally require further treatment after removal. Benign neuroendocrine tumors that are screened, diagnosed, and treated as early as possible can usually be cured with surgical resection. After resection of malignant neuroendocrine tumors, according to the comprehensive judgment of pathological results, staging, and patient’s own condition, adjuvant radiotherapy, chemotherapy, targeted therapy, etc. may be needed to improve the prognosis and cure rate. Meanwhile, neuroendocrine tumors require different review and follow-up plans based on tumor location, grading, size, and stage. Once diagnosed with neuroendocrine tumor, it is necessary to seek medical treatment as soon as possible to avoid delay.
