Answer: Growth factors are signaling molecules that stimulate cell growth and division. In the presence of growth factors, mutated cells may grow and divide more rapidly than they would in the absence of growth factors. This can lead to the development of tumors and cancerous growths.
Without the presence of growth factors, mutated cells may still grow and divide, but at a slower rate. The absence of growth factors can limit the ability of mutated cells to form tumors or metastasize to other parts of the body.
In summary, the presence of growth factors can stimulate the growth and division of mutated cells, potentially leading to the development of cancer. In contrast, the absence of growth factors may limit the growth and spread of mutated cells.
