MEN2, or Multiple Endocrine Neoplasia Type 2, is a genetic disorder that affects the endocrine system, leading to tumors in various glands. It primarily involves the thyroid gland, parathyroid glands, and adrenal glands. People with MEN2 are at a higher risk of developing certain types of cancers, including medullary thyroid carcinoma and pheochromocytoma. This condition is inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene from a parent can cause the disorder. Early diagnosis and regular monitoring are crucial for managing the symptoms and reducing the risk of complications associated with MEN2.
