neoplasia

 [ne″o-pla´zhah]
the formation of a neoplasm.
cervical intraepithelial neoplasia (CIN) dysplasia of the cervical epithelium, often premalignant, characterized by various degrees of hyperplasia, abnormal keratinization, and the presence of condylomata.
multiple endocrine neoplasia (MEN) a group of rare hereditary disorders of autonomous hyperfunction of more than one endocrine gland. In Type I (MEN I), called also Wermer's syndrome, there are tumors of the pituitary, parathyroid gland, and pancreatic islet cells in association with a high incidence of peptic ulcer. Type II (MEN II), called also Sipple's syndrome, is characterized by medullary carcinoma of the thyroid, pheochromocytoma, often bilateral and multiple, and parathyroid hyperplasia. Type III (MEN III), called also mucosal neuroma syndrome, resembles Type II except that parathyroid hyperplasia is rare, the mean survival time is shorter, and there may be neuromas and neurofibromas. All forms are transmitted as autosomal dominant traits.

Patient discussion about neoplasia

Q. What is a brain tumor?

A. A brain tumour is any intracranial tumor normally either in the brain itself in the cranial nerves, in the brain envelopes, skull, pituitary and pineal gland, or spread from cancers primarily located in other organs (metastatic tumors). It is created by abnormal and uncontrolled cell division. Primary (true) brain tumors (which start in the brain) are commonly located in the posterior cranial fossa in children and in the anterior two-thirds of the cerebral hemispheres in adults, although they can affect any part of the brain.

Q. Is this a tumor? I felt a lump in my breast a few days ago in the shower. Is this a Tumor? Help! I'm scared.

A. If you felt a lump in your breast then you should go see your Doctor to check whether or not it is something that could be dangerous.

Q. what is carcinoid tumors? I had my appendix removed and the doctor came in the room very shocked and said it was full of carcinoid tumors. Im scared to get them somewhere else.

A. ya I have pain all the time but the doctors wont give me anything cuz im so young they don't want me hooked on anything. thank you sooo much for being so kind.
