A glucagonoma is a type of tumor located in the pancreas that produces glucagon, a hormone involved in increasing blood sugar levels. These tumors, which can either be malignant (cancerous) or benign (non-cancerous), can potentially result in episodes of hyperglycemia (high blood glucose) due to the overproduction of glucagon.
