Some genes get damaged every day and cells are  This is so the protein can perform the correct function for the cell. All cancers begin when one or more genes in a cell are mutated, or changed. This creates an abnormal protein or no protein at all. An abnormal protein provides different information than a normal protein, which can cause cells to multiply uncontrollably and  The causes of bowel cancer or risk factors can come from something you do (poor exercise and diet) or something you have no control of (age, genetics).

The remaining 5–10% are due to inherited genetics. Environmental, as used by cancer researchers, means any cause that is not inherited genetically, such as lifestyle, economic and behavioral  Cancer is a complex group of diseases with many possible causes. In this section you can learn more about the known causes of cancer, including genetic factors; lifestyle factors such as tobacco use, diet, and physical activity; certain types of infections; and environmental exposures to different types of chemicals and  Causes. It's not known exactly what causes womb cancer, but certain things can increase your risk of developing it. Cancer begins with a change (mutation) in the structure of the DNA in cells, which can affect how they grow. This means cells grow and reproduce uncontrollably, producing a lump of tissue called a tumour. The root cause of cancer is microbes and parasites that are in the organs or colon (or bloodstream), which weakens the immune system. Do you ever eat these top ten cancer causing foods?
