ABC of the oncología

That neoplasia is one?
?The tumors or neoplasias are abnormal proliferations of the weaves that begin apparently of spontaneous way (the cause is not known), of progressive growth, without capacity to arrive at defined, devoid a limit of purpose and regulated by own laws more or less independent of the organism. ? Definition of Barbacci.

This definition, that or has a few tens of years, simplifies to the definition of which is a tumor, but if we did not take the time to understand it and to analyze it, surely we find definitions but technical or but simple but we are trying to include/understand to the so complex one that at the present time it is a specialty but within the Medicine.

Are synonymous Neoplasia and Cáncer? No! The tumors can have benign behavior (benign tumor) or malignant (malignant tumor called cancer).

Benign tumor: In general they do not produce any significant damage even though that their proliferation this outside control but the abnormal cells remains grouped in a unique mass, encapsulated and whose treatment is possible by means of the extraction of this tumor in most of the cases.

Malignant tumor: Or also call cancerous cancer or these cells are able to invade neighboring weaves and this invading capacity implies the capacity to free itself of the neighboring cells to enter the sanguineous torrent o/y in the lymphatic glasses to invade distant weaves and to form secondary malignant tumors or metástasis.

There are races but prearranged that others in the canine ones are the case of the Boxer, another predisponente factor is the color of the coat and the skin. Several environmental factors exist (the sun, the feeding etc.) that favor and produce genetic alterations and prearrange to the appearance of some types of cancer.
A classic example is the cancer of skin by fotosensibilizacion since in those patients without or with little cutaneous pigmentación in zones exposed to the sun (nose and ears etc?.) the risk of skin cancer is high.
Clarifying example: Many of the cats in areas without pigmenting and with little hair, before the reiterated sun exhibition in those (ultra-violet rayses), undergo in the skin an irritation, specially in the ends of the ears and in the nose, later this gives to place a characteristic injury (scabs, reddening called etc. actinic queratosis) that after same and before the repeated solar exhibition the cells begins to mutar (it changes the constitution of his DNA) and desarolla finally one neoplasia in the skin, at the beginning of benign behavior, with later malignización: skin cancer (carcinoma of escamosas cells).
This case is ejemplificador to understand that many tumors can have in the different stages different behaviors and that being oncología (science that studies the tumors) nothing he is static nor exact.
Also it clarifies to us as the environmental factors affect the appearance of this disease.

In the future in veterinary medicine also we will have to disposition the oncológica inmunoterapia and the genic therapy but we will even have to wait for a little due to the costs and the little accessibility to this type of treatment since even in humans this in the heat of development and investigation.
