Glioblastoma multiforme (GBM) is a highly aggressive and deadly type of brain tumor that arises from astrocytes, the supportive cells in the brain. Recognizing the signs of glioblastoma early can be challenging because symptoms often start subtly and worsen gradually…
Oligodendroglioma is a type of brain tumor that originates from the oligodendrocytes, which are a type of glial cell responsible for producing myelin, the fatty substance that surrounds and protects nerve fibers in the brain. These tumors are generally classified…
Astrocytoma is a type of brain tumor that starts in star-shaped cells called astrocytes, which are part of the supportive tissue in the brain. These tumors can happen anywhere in the brain and affect both adults and children. The symptoms…
Medulloblastoma is a type of malignant brain tumor that primarily affects children, arising in the cerebellum, which is the part of the brain responsible for coordination and balance. Understanding what causes medulloblastoma involves exploring its origins at the cellular and…
Paraganglioma is a rare type of tumor that arises from paraganglia, groups of neuroendocrine cells located along nerve pathways in various parts of the body, including the head, neck, chest, abdomen, and pelvis. These tumors can be either benign or…
Pheochromocytoma-related hypertension is a complex condition that arises from a rare type of tumor known as a pheochromocytoma. These tumors are primarily found in the adrenal glands, which are small glands located on top of each kidney. However, about 10%…
Zollinger-Ellison syndrome (ZES) is a rare condition characterized by tumors called gastrinomas that produce excessive amounts of the hormone gastrin. This hormone stimulates the stomach to produce too much acid, leading to a range of complications primarily related to the…
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…
