Growth-promoters agents hormones

Despite those advantages, use of these growth-promoting agents has been prohibited in the European Union since 1989. As a consequence, a ban has been implemented on imports of red meat from animals treated with growth-promoting hormones, cutting off US beef exports to the European Union valued at about 100 million annually.

Community. The administration of hormone growth promoters was prohibited because of fears about health effects from residues, although there is a need to standardise conditions of trade in animal products from countries outside the EU where these compounds are still licensed for use. The use of one particular group of synthetic anabolic agents with oestrogenic activity, the stilbene compounds,... 

Steroid Hormones. Anabolic hormones like testosterone and its synthetic analogues such as trenbolone have been widely used in beef production for several years. The non-steroidal anabolic agent zeranol has also been widely used for this purpose (14). Growth promoting uses of all steroid hormones were recently banned by the European Community, but various zootechnical (eg synchronization of estrus) and therapeutic (eg prevention of abortion) uses of the endogenous hormones and their synthetic esters are permitted (15,16). 

Substances such as promoters that interfere with cell-to-cell communication allow cancer cells to proliferate wildly. But cell proliferation can be induced by other means as well. Toxicity or other types of injury to tissues can result in a proliferative response. So can certain natural and synthetic hormones, such as estrogens, cause proliferation of certain tissues, such as the breast. Chronic viral infections may cause cell killing and its consequence is cell proliferation. It appears that sustained chronic proliferation induced in any of these ways, either by agents foreign to the body or some, such as the estrogens, that are natural to it, can increase tumor growth. 

Anabolic agents to promote growth. This group includes hormones and some antimicrobial substances.
