What is MEN2b?
(Multiple Endocrine Neoplasia Type 2b) aka MEN3
MEN2b is a rare genetic condition that affects the endocrine system. It affects glands in the body that make hormones. Hormones are like little messengers that help the body grow and stay healthy.
In MEN2b, some glands can become too active and may form growths. One hormone, called calcitonin, may be higher than usual. Doctors can check this with a simple blood test.
Everyone with MEN2B is unique. These are some things doctors may notice.
Connection, care, and community make a big difference.
