ENVIRONMENTAL AND ANTHROPOGENIC CARCINOGENS AND THEIR CARCINOGENIC EFFECTS ON HUMANS

Abstract

The review describes the environmental and anthropogenic carcinogens and their carcinogenicity. Environmental and anthropogenic carcinogens can be chemicals (exposed from chemical industries, alcoholic beverages, welding and wood dust, etc.), radiations (UV-rays, X-rays, γ-rays, radon, neutron, thorium, etc.), microbiological agents (viruses and bacterial infections), and natural products (tobacco, nicotine, areca nut, yerba mate, safrole, cycasin, etc.). Diet related factors (heterocyclic amines, saccharine, cyclamate, etc.) are through to account for about 30-35% of cancers in developing and developed countries. Obesity may raise incidence of cancer in the oesophagus, breast, colorectum, endometrium, and kidney. Key words: Carcinogens, environmental and anthropogenic carcinogens, chemotherapy, harmone therapy.
