Web8 de fev. de 2015 · Cancer is simply uncontrolled cell division. In the cell, mitosis is always tightly regulated. If the cell has errors in it (faulty DNA, for example), the regulator proteins will not allow it to divide. In addition, there are several processes that stimulate cell growth. For example, if cells receive certain signals, then they begin to divide. WebCarcinogens are substances in our everyday environment that can cause mutations that lead to cancer.
