Cancer of the Islet Cells (Islet Cell Carcinoma)
Islet cell cancer is a rare but highly treatable type of pancreatic cancer that begins in the cells of the pancreas that produce insulin and glucagon. Islet cell cancer can cause the pancreas to produce too much insulin or glucagon. When this happens, the patient may feel weak or dizzy and may have chills, muscle spasms, and diarrhea as well as pain in the stomach or abdomen. Islet cell cancer is also called islet cell carcinoma.
