About 10 per cent of the human cancers are caused by industrial toxins. Most of the industrial toxins such as benzene, polychlorinated biphenyls (PCBs), diesel exhaust, hair dyes, mineral oils, painting materials, lead, arsenic, mercury, aluminium, nickel and cadmium have carcinogenic effect. These industrial carcinogens may lead to genesis of cancer after entering the human body.
Lead enters the human body from various sources including canned food, cooking utensils and rusted water pipes. The common sources of cadmium are instant tea, coffee, soft drinks, fungicides, nickel-cadmium batteries and plastic items. Mercury may find its way into the human body through paints and dental fillings. The common sources of aluminium are drugs, deodorants, foils and utensils.
After entering the human body, these toxins accumulate in various tissues and organs of the body such as the breast, brain, bones, glands, hair and the fat tissue. The bioaccumulation of industrial toxins in the human body may cause cancer by damaging the DNA.
Incidence of the lung and the skin cancers is much higher among the tanners, oil refinery workers and the insecticide sprayers due to the arsenic exposure. It has been observed that incidence of the lung cancer is much higher in the shipyard workers, demolition experts and the brake-lining mechanics due to the asbestos exposure. Similarly, hospital workers, laboratory staff and wood-product manufacturers are exposed to formaldehyde that may lead to cancer.
The metal refining industries release a large amount of fluoride compounds into the atmosphere, which may enter food chain after raining down on the agricultural land. Fluoride compounds commonly found in water are actually unrefined toxic waste products of phosphate fertilizers. Sodium fluoride is the toxic waste product of aluminium industry. Fluoride compounds may cause cancers of the bone, skin and the oral cavity.
In a recent study conducted by the Environmental Protection Agency of USA, more than 400 toxic chemicals have been found in the human body, out of which 48 were found in the fat tissue, 40 in the breast, 73 in the liver and 250 in the blood. A study conducted by Dr. Hildegarde L.A. Staninger, an expert in industrial toxicology, has revealed that tissue samples of the prostatic cancer patients contain arsenic, dichloro-diphenyl-trichloroethane (DDT) and Chlordane in abnormally higher concentrations.
Studies have shown that the women living in vicinity of the toxic-waste dumpsites have much higher incidence of the breast cancer due to certain chemicals, which mimic the activity of oestrogen. It has been observed that many weak environmental oestrogenic chemicals have synergistically enhanced combined effect, for example a combination of Dieldrin, Endosulfan and Toxaphene produces a thousand times enhanced oestrogenic effect. Endosulfan is known to aggravate cancers of the testis and the breast.
