cervical intraepithelial neoplasia  (CIN) dysplasia of the cervical epithelium, often premalignant, characterized by various degrees of hyperplasia, abnormal keratinization, and the presence of condylomata.

gestational trophoblastic neoplasia  (GTN) a group of neoplastic disorders that originate in the placenta, including hydatidiform mole, chorioadenoma destruens, and choriocarcinoma.

multiple endocrine neoplasia  (MEN) a group of rare diseases caused by genetic defects that lead to hyperplasia and hyperfunction of two or more components of the endocrine system; type I is characterized by tumors of the pituitary, parathyroid glands, and pancreatic islet cells, with peptic ulcers and sometimes Zollinger-Ellison syndrome; type II is characterized by thyroid medullary carcinoma, pheochromocytoma, and parathyroid hyperplasia; type III is similar to type II but includes neuromas of the oral region, neurofibromas, ganglioneuromas of the gastrointestinal tract, and café-au-lait spots.

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 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. i think the shock was not to find carcinoid tumors in the appendix...it's your age...you usually find this tumors at people over 60...
i think the next stage is colonoscopy, to look for more, not that you have more, just to make sure. but didn't the Doctor told you that? i would look for a consultation with a gastro specialist about it..

Q. Is it safe to have sex with a woman with cancer of the uterus? My 45-years old wife was told she have cancer in the uterus, and will have an operation soon. Meanwhile, should we use a condom during sex? Can the tumor pass from her to me (like AIDS or HPV)?

A. unless the cancer has lots of bleeding, you don't need to use condoms.
but if your wife would undergo an operation, maybe you need to be off-of-that-sex 1-2 days prior to operation day, just to make sure there's no super infection that will bother the operation plan.

Q. How do doctors find out if a tumor is malignant? What procedure is done to see if a tumor is malignant? Is a simple MRI enough to make that conclusion?

A. It depends on what type of tumor- what organ is involved and how big is it. Sometimes a simple blood test can show high levels of tumor markers and sometimes just the shape and size of it on CT or MRI can hint that it is a malignant tumor. However, the final answer can only be by biopsy or removal of the tumor and microscopic tests (that's the pathology work-up the doctors send).
