Tumours
A tumour is a typical pathological process. It is characterized by potential boundlessness of uncontrolled growth, and also atypical cells and tissues and ability to pass these properties to future generations of cells on heredity.

Ephithelial tumours
Depending on a hystogenesis distinguish tumours from an integumentary epithelium (multi-layered flat and transitional) and ferrous. According to motion and differentiation ephithelial tumours are benign and malignant. Depending on organ specificity select specificity organonspecificity and ephithelial tumours without specific localization.

Benign integumentary epithelium tumours without characteristic localization
- villomas (papilomas) meet in a skin, larynx, urinary bladder and others like that, from ferrous epithelium. Adenomas meet in all ferrous organs. They call the followings morphological variants of adenomas: acinous (alveolar), tubular, trabecular, solid, nipple cystadenomas, villiferous adenoma, fibroadenoma.

Malignant ephithelial tumours have name cancer or carcinoma. They
distinguish the followings forms of cancer without specific localization: flatcells cancer which develops from multi-layered flat epithelium and meets in the proper tissues or in mucuses, where a flatcells metaplasia took place.

Tumours of melaninproducing tissue
develop from the cells of neuroektodermal origin – melanocytes, which are in the basal layer of epidermis, hair follicles, leptomeninges and retina. Melanocytes can be the source of tumular formations – nevus and malignant tumours – melanomas.

Properties of tumours
unlimitedness of growth; boundlessness of growth; uncontrolled of growth; cells anaplasia.

Types of anaplasia (kataplasia) morphological; biochemical; physical and chemical; immunological.

Etiology of tumours
It is set, the tumours can be caused by physical, chemical and biological agents, which are named carcinogens.
Over 75% cancers diseases at people are caused by the factors of external environment and in the first order – by chemical compounds.

Description of benign and malignant tumours
Benign Malignant
Have insignificant deviations from maternal tissue
Atypіzm is expressed
Expansive growth Infiltrative growth
Grow slowly Grow quickly
Achieve largenesses Rarely achieve largenesses
Formed sore rarely Formed sore often
Does not give metastases Give metastases
The relapse is not characteristic The relapse is often
The common state of patient violates a little
Have a considerable influence on all organism
