	Adenoma - Wikipedia, the free encyclopedia
		Adenoma is a benign epithelial tumor arising in epithelium of mucosa (stomach, small intestine and bowel), glands (endocrine and exocrine) and ducts.
		Depending on the type of the insertion base, adenoma may be pedunculated (lobular head with a long, slender stalk, covered by normal mucosa) or sessile (broad base).
		Pituitary adenomas are commonly seen in 10% of the neurological patients.

		adenoma of the thyroid in which the cells are arranged in the form of follicles.
		an endocrine-active adenoma that secretes two or more hormones, usually growth hormone and one or more of the glycoprotein types, so that its effects are similar to those of a combination of other adenomas such as the growth hormone–secreting adenoma and the glycoprotein hormone adenoma; it may be mixed-cell or a single cell type.

		A bronchial adenoma is a glandular tumor in the trachea or large bronchi (the large airways of the lung) that usually causes obstruction of the airway.
		Although the term bronchial adenoma classically refers to a benign tumor of the airway -- also known as a mucous gland adenoma -- it is often misapplied to malignant tumors such as carcinomas and carcinoids of the airways.

		Nonfunctional adrenal cortical adenomas are not premalignant, and surgical excision is not indicated.

		Whereas the four adenoma cell lines were anchorage-dependent and did not form tumours in nude mice (Williams et al, 1990; Hague et al, 1997), the carcinoma cell lines were anchorage-independent and tumorigenic after subcutaneous injection in nude mice.
		In early adenomas, there is apoptosis close to the basement membrane, particularly at crypt branching points (Brodie et al, 2004), whereas crypt lumen apoptosis is a feature of larger adenomas, high-grade dysplasia and adenocarcinomas.
		Importantly, since the adenoma cultures are grown under the same culture conditions as the carcinoma cultures, this cannot be attributed to differences in survival factors or medium composition.

	Immunotherapy in the Treatment of an Adenoma Prostate and Prostate Cancers
		According to different sources, the BPH or adenoma prostate is present approximately in case of 20 % of the men at the age of 40 years, 70 % at the age of 60 and 90 % at the age of 80 years and above [1, 19, 37, 38].
		The increasing mass of the adenoma causes considerable elongation and compression of urethra and may result into severe cystectasia due to back flux of urine from urinary vessel into upper urinary paths, severe urination disorder (frequent and difficult), chronic urinary tract infections, renal insufficiency and acute dysuria which requires emergency catheterization of the urinary vessel.
		As in case of BPH or Adenoma Prostate the prostate cancers are also seen mostly after 40 years of age.
