Environmental Factors That Cause Cancer Cancer is caused by the alteration of genes in our bodies, which in turn change the function of cells. Natural modifications of these genes occur during cell division through the replication of DNA. However, environmental factors have also proven to contribute to the changes in DNA, which alternatively cause cancer (Parsa, 2012). Long time exposure to specific environmental substances may lead to gene alterations which accumulate in our cells. Although most of these changes might not affect an individual’s health, permanent changes may eventually lead to cancer. Overexposure to specific environmental agents is likely to cause cancer, regardless of the genetic make-up.             One environmental factor is the use of tobacco. Every year, approximately one-third of cancer deaths in America are associated with carcinogens found in tobacco (Jemal, Bray, Ferlay, Ward & Forman, 2011). All the various means of consumption, which include chewing, pipe smoking, cigarette smoking, cigars and...
