Knowledge gained in the discipline of human cancer genetics reflects a growing consensus about how particular cancer-causing genes contribute to the overall frequency of cancer in the general population. cancer risk can be viewed as a contributor of genetic susceptibility and environmental forces. While some genes are of themselves cancer-causing, must be based on a combination of environmental and an inherited factor.
