a cancer that produces too much production of a hormone called glucagon, which does reduce insulin production
a tumor of the pancreas that produces the hormone glucagon, which raises the level of sugar (glucose) in the blood and produces a distinctive rash
Rare type of endocrine tumour of the pancreas which secretes (makes and releases) abnormal amounts of a hormone called glucagon.
A glucagonoma is a rare tumor of the alpha cells of the pancreas that results in up to a 1000-fold overproduction of the hormone glucagon. Alpha cell tumors are commonly associated with glucagonoma syndrome, though similar symptoms are present in cases of pseudoglucagonoma syndrome in the absence of a glucagon-secreting tumor.
