Insulinoma is a rare type of tumor that develops in the pancreas and produces excessive amounts of insulin. This can lead to low blood sugar levels (hypoglycemia) and symptoms such as confusion, sweating, and fainting. Insulinomas are usually benign, meaning they do not spread to other parts of the body. Treatment typically involves surgery to remove the tumor. Research in the area of insulinoma focuses on identifying risk factors, improving diagnostic techniques, and developing new treatments to better manage this condition.
