Multiple Endocrine Neoplasia Type 2 (MEN 2) is a rare genetic disorder that affects the endocrine system, which produces hormones. People with MEN 2 have a higher risk of developing tumors in various glands, particularly the thyroid, parathyroid, and adrenal glands. There are two main forms: MEN 2A and MEN 2B, each with different tumor patterns and symptoms. This condition is caused by mutations in the RET gene, which plays a crucial role in cell growth and development. Early detection and treatment are essential to manage the tumors and reduce complications. Regular check-ups and genetic counseling can help those at risk.
