ABSTRACT

There are many types of environmental pollution and some of them cause cancer . Many studies have discovered the link of the various types of environmental pollution with the development of cancer

Cancer is spread through any of the media of pollution namely through water pollution , air pollution and land pollution

In water pollution the common sources of cancer

are heavy metals , toxic organic chemicals and leachates from waste disposal site . The heavy metals like acenic and cardinium are highly toxic and cause cancer at very low concentration

Through land pollution cancer is spread by exposure of human beings to pesticides , radioactive materials and heavy metals . Some pesticides are highly toxic , non bio -degradable and persist in the environmental for a very long period of time

Cancer spread through the exposure of people particulate matter volatile organic compounds and through radioactive matters in air

Environmental pollution is inevitable and necessary part of life for people who depend on technology . Therefore to curb and reduce the spread of cancer measures of controlling and reducing air pollution , water pollution and land pollution must be employed INTRODUCTION

There are many types of environmental pollution and some of them cause cancer . Many studies have discovered the link of the various types of environmental pollution with the development of cancers

Pollution is the undesirable change in the physical , chemical or biological characteristic of air , land and water which harmfully affects human life and other resources . The driving forces for environmental pollution are high human population , the overconsumption of resources due to affluence and use of inappropriate technology . Cancers incidents are affected more by causes of pollution especially air pollution . Water pollution has also some effects which affect humans but their instances on cancer are minimal

Cancer is the abnormal division or multiplication of cells . The abnormal multiplication of blood cells may cause Leukemia . There are three media cause of pollution . Where cancer can originate from which are land pollution , water pollution and atmospheric pollution

Cancer can be spread through water pollution , ground water pollution and through ocean pollution . Through water exposure of substances like heavy metals , toxic organic chemicals and lactates from waste disposals Pollution from agricultural activities , hazardous waster and illegal dumping causes cancer to human beings

Under land pollution , the exposure of human beings to wastes like heavy metals , pesticides used in agricultural activities leads to the spread of cancer . Causes of cancer in the air include suspended particulate matter , volatile organic compounds , heavy metals and radioactive materials

pollution is the contributor to the spread of lung cancer . The use of domestic fuels for cooking causes lung cancer . When biomass is used for cooking it causes lung cancer to women who get exposes to its smoke for a period of 4 to 6 hours a day . When a medical examination is done symptoms like meta static...
