WebCancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. http://ib.bioninja.com.au/standard-level/topic-1-cell-biology/16-cell-division/mitotic-index.html
