Islet Cell Tumor

Islet cell tumors, also known as neuroendocrine tumors, are rare cancers that develop in the islet cells of the pancreas. Islet cells produce hormones that regulate blood sugar levels, such as insulin and glucagon. When these cells become cancerous, they can produce excessive amounts of hormones, leading to various symptoms and complications.

Islet cell tumors can be either functioning or non-functioning. Functioning tumors produce hormones, while non-functioning tumors do not.
