Somatostatinoma is a rare type of neuroendocrine tumor that arises from the delta cells in the pancreas or, less commonly, in the duodenum. These tumors produce excessive amounts of somatostatin, a hormone that normally inhibits the release of several other…
VIPoma, also known as Vasoactive Intestinal Peptide tumor, is a rare type of neuroendocrine tumor that primarily affects the pancreas but can also occur in other parts of the body. These tumors produce excessive amounts of vasoactive intestinal peptide (VIP),…
## What Causes Gastrinoma? Gastrinoma is a rare type of tumor that causes the body to produce too much gastrin, a hormone that tells the stomach to make acid. This extra acid can lead to serious problems like ulcers in…
Glucagonoma is a rare type of tumor that arises from the alpha cells of the pancreas, which produce the hormone glucagon. This tumor causes an overproduction of glucagon, leading to a distinct set of symptoms primarily related to its effects…
Insulinoma is a rare tumor of the pancreas that causes excessive production of insulin. It arises from the beta cells in the islets of Langerhans, which are the parts of the pancreas responsible for producing insulin. Normally, insulin helps regulate…
Pancreatic neuroendocrine tumors (PNETs) are a rare type of tumor that arises from the hormone-producing cells of the pancreas. Unlike the more common pancreatic adenocarcinoma, which originates from the exocrine part of the pancreas, PNETs can produce hormones that cause…
Gastrointestinal stromal tumors (GISTs) are a type of tumor that arises in the digestive tract, most commonly in the stomach or small intestine. The primary cause of GISTs is genetic mutations that lead to abnormal activation of certain proteins called…
Carcinoid tumors are a type of neuroendocrine tumor that most often arise in the gastrointestinal tract or lungs. Treating these tumors involves a variety of approaches depending on the tumor’s size, location, whether it has spread, and the symptoms it…
Non-seminomatous germ cell tumors (NSGCTs) arise primarily from abnormal growth of germ cells, which are the cells responsible for producing sperm in the testicles. These tumors develop when germ cells undergo genetic and cellular changes that cause them to multiply…
Seminoma is a type of testicular cancer that primarily affects the germ cells in the testicles. Recognizing its signs early is crucial because it can be treated effectively when detected promptly. The signs of seminoma often overlap with those of…
