Adenoma
* Some adenomas stay harmless.
* arise from mucous glands or areas of mucous metaplasia.
* is benign tumors
  - diseases

### condition | illness | tumor | adenoma:

Fibroadenoma
* Some fibroadenomas are polyclonal hyperplasias.
* are adenoma
  - another type of generally benign breast lump
  - benign tumors which grow in the breast tissue outside the ducts
  - smooth and round
  - solid, benign breast lumps
* are the most common benign solid lesion of the breast
  - tumors found in women's breasts
  - tumors that are usually painless, can be easily moved around and feel rubbery
  - usually harmless, marble-like lumps of tissue
* feel rubbery and can be moved around easily.
* have a benign appearance on mammography.
* is adenoma
  - the most common benign, solid growth in the breasts
* never turn into cancer.
* occur most often in women under thirty, and are more common in black women
  - twice as often in African-American women as in other American women
* often stop growing or even shrink on their own without any treatment.
* tend to regress with time.
* usually appear clearly on mammogram or ultrasound.

Hepatic adenoma
* are usually solitary and are associated with a history of oral contraceptive use
  - lesions
* creates an increase in vascularity which can result in bleeding episodes.
* is an unusual complication of pregnancy.

Pituitary adenoma
* Most pituitary adenomas are microadenomas.
* are also benign and compress rather than invade surrounding tissue
  - overgrowths of one or more of the cell types in the gland
  - relatively common in old rats
  - usually isointense with and also with normal pituitary gland
* arise in and consist of adenohypophysial cells.
* arises as a small nodule in the anterior pituitary gland.
* can grow extensively into the base of the skull, as well.

Pleomorphic adenoma
* are the most prevalent of benign salivary gland tumors.
* have a tendency to recur.

Advanced tumor
* More advanced tumors are usually large, ulcerated and fungating.
* are frequently unresectable and treated with radiotherapy.

### condition | illness | tumor:

Benign tumor
* Most benign tumors require treatments.
* Some benign tumors can have estrogen production with resulting menstrual problems
  - cause many symptoms
  - disappear on their own
  - occur in spines
* are defined by their behavior
  - never life-threatening
  - non-cancerous and can be removed in surgery
  - noncancerous, and malignant tumors are cancerous
  - self-contained
  - usually carry the suffix -oma
* can also affect the tongue
  - be life threatening if they are located in a vital area
  - cause problems because of their spread, as they press and displace normal tisues
  - disrupt normal function by releasing hormones or by crowding nearby tissue
  - go through further genetic change and turn into malignant tumors
  - include leiomyomas, fibromas, neurofibromas, and lipomas
* grow by expansion.
* have less of a tendency to invade and are less likely to metastasize
  - well-defined borders
* push normal cells away as it grows.
* remain localized as a discrete mass.
* tend to appear red.

Benign tumour
* are hard and painless and much less common than in the parotid gland.
* cause damage by taking up space and pressing on important organs.
* remain contained within a localised area and once treated.
* stay in one place and usually stop growing when they are quite small.

Bladder tumor
* Most bladder tumors are papillary transitional cell carcinomas.
* occur more frequently in female dogs and male cats.

Bone tumor
* are also common
  - painful, and excision is the best way to relieve the pain
  - rare during pregnancy
* form matrix just as a normal bone does, but sometimes in greater quantity.
