Multiple endocrine neoplasia is a group of disorders that affect the body's network of hormone-producing glands called the endocrine system. Hormones are chemical messengers that travel through the bloodstream and regulate the function of cells and tissues throughout the body. Multiple endocrine neoplasia typically involves tumours (neoplasia) in at least two endocrine glands; tumours can also develop in other organs and tissues. These growths can be noncancerous (benign) or cancerous (malignant). If the tumours become cancerous, the condition can be life-threatening.

Multiple endocrine neoplasia is a group of disorders that affect the body's network of hormone-producing glands called the endocrine system. Hormones are chemical messengers that travel through the bloodstream and regulate the function of cells and tissues throughout the body. Multiple endocrine neoplasia typically involves tumours (neoplasia) in at least two endocrine glands; tumours can also develop in other organs and tissues. These growths can be noncancerous (benign) or cancerous (malignant). If the tumours become cancerous, the condition can be life-threatening.
The major forms of multiple endocrine neoplasia are called type 1, type 2, and type 4. These types are distinguished by the genes involved, the types of hormones made, and the characteristic signs and symptoms.
Many different types of tumours are associated with multiple endocrine neoplasia. Type 1 frequently involves tumours of the parathyroid glands, the pituitary gland, and the pancreas. Tumours in these glands can lead to the overproduction of hormones. The most common sign of multiple endocrine neoplasia type 1 is overactivity of the parathyroid glands (hyperparathyroidism). Hyperparathyroidism disrupts the normal balance of calcium in the blood, which can lead to kidney stones, thinning of bones, nausea and vomiting, high blood pressure (hypertension), weakness, and fatigue.
The most common sign of multiple endocrine neoplasia type 2 is a form of thyroid cancer called medullary thyroid carcinoma. Some people with this disorder also develop a pheochromocytoma, which is an adrenal gland tumour that can cause dangerously high blood pressure. Multiple endocrine neoplasia type 2 is divided into three subtypes: type 2A, type 2B (formerly called type 3), and familial medullary thyroid carcinoma (FMTC). These subtypes differ in their characteristic signs and symptoms and risk of specific tumours; for example, hyperparathyroidism occurs only in type 2A, and medullary thyroid carcinoma is the only feature of FMTC. The signs and symptoms of multiple endocrine neoplasia type 2 are relatively consistent within any one family.
Multiple endocrine neoplasia type 4 appears to have signs and symptoms similar to those of type 1, although it is caused by mutations in a different gene. Hyperparathyroidism is the most common feature, followed by tumours of the pituitary gland, additional endocrine glands, and other organs.

However, in a very small number of people, it can be the result of an inherited condition called familial isolated hyperparathyroidism. Also, rarely, it may be inherited as part of a collection of problems (a syndrome) called multiple endocrine neoplasia (MEN) which affects the parathyroids, the pancreas and the pituitary gland.

ए prolactinoma is a non-cancerous growth in the pituitary gland that makes a hormone called prolactin. Tucked away deep inside your brain is a gland called your pituitary gland. A prolactinoma occurs when some of the cells in the पिट्यूटरी ग्रंथि (the ones producing prolactin) multiply more than usual to form a small growth (tumour) in the.

मायलोमा
Myeloma is a cancer that affects cells, called plasma cells, in the bone marrow. Bone marrow is the spongy tissue at the centre of some bones that produces the body's blood cells. As the cancerous plasma cells fill the bone marrow, you are not able to make enough normal blood cells. This can lead to anaemia, bleeding problems and infections. Other.
