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…
Embryonal carcinoma is a type of malignant germ cell tumor that arises from primitive, undifferentiated cells resembling early embryonic tissue. It is most commonly found in the testes and ovaries but can occasionally occur in other locations such as the…
Choriocarcinoma is a rare but aggressive type of cancer that arises from trophoblastic cells, which are cells that normally develop into the placenta during pregnancy. Because it originates from pregnancy-related tissue, its symptoms often relate to abnormal bleeding and signs…
A yolk sac tumor is a rare type of cancer that originates from germ cells, which are the cells in the body responsible for developing into sperm or eggs. These tumors are called “yolk sac” because they resemble the yolk…
