Normal cells have their growth regulated by a balance between products produced by oncogenes, which promote entering and completing the cell cycle, with those of products produced by suppressor genes, which restrict or inhibit entering and moving through the cell cycle. Thus, suppressor gene products inhibit all aspects of mitosis and also trigger apoptosis. As a result, cell division occurs only when it is needed, and environmental conditions can support more cells.
