* Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues (Source: Cancer Free, Philip Bashe, Simon & Schuster, 1994). * Cancer cells can spread to other parts of the body through the blood and lymph systems (Source: Cancer Free, Philip Bashe, Simon & Schuster, 1994). * There are many types of cancers such as prostate cancer, breast cancer, lung cancer, stomach cancer and etc. * Most cancers arise from interactions of many causes (Source: Health Today, Treating Cancer Then & Now, Dr Lim Chiao Mei, Aug 2012). * It is helpful to know what happens when normal cells become cancer cells. * It is very important to know about cancer because a cancer diagnosis is difficult to cope with. * When cells become old or damaged, they die and are replaced with new cells (Source: National Cancer Institute: Acrylamide in Food and Cancer Risk; July 29, 2008) * It is necessary that we know that cancer can cause from genetics, tobacco as well as diet and physical activity and the ways to overcome cancer are good dietary, developments in systemic therapies and control body weight.
1. One cause for this disease is from genetics. (Source: Cancer Free, Philip Bashe, Simon & Schuster, 1994) * Cancer is caused by an abnormal gene that is being passed along from generation to generation. * Genes are found on long strands of DNA called chromosomes. * Each chromosome is a collection of genes, strings of chemical material called DNA that control every physical, biochemical and physiologic trait, from hair color to intellect to the level of cholesterol in the bloodstream. * When someone has inherited an abnormal copy of a gene, their cells already start out with one mutation. * That is why cancers that are inherited tend to occur earlier in life than cancers of the same type that are not inherited.
