The diploid human genome contains 23 pairs of chromosomes whose DNA encodes genes for life activities, such as cell division. Cancer corrupts those genes, making growth-promoting genes more active (oncogenes) or growth-inhibiting genes (tumor suppressors) less active. One of the most common genetic alterations causing... click to read more
