Whether cancer cells? Cancer cells generally is defined as a cell that does not Normal, which grow and multiply quickly and uncontrollably. Cell Cancer is not concerned with food substances, limitations of space and the fact that they Had to share it with the normal cells that exist around them. Furthermore, they Ignoring orders to stop multiplying by the body concerned. Normal body cells also grow, divide, and at any given moment theyWill die. But in cancer cells, they continue to grow, reproduce and Trying to avoid his death (apopt sis), worse again speed Cancer cell growth far exceeded the normal cells. Generally cancer is divided into two groups, the cancer is benign and cancer malignant. Cancer is benign (benign) have a tendency to grow slower than malignant cancer and they do not spread to other in the body. While The malignant cancers (malignant) have a very rapid cell growth, it can invade and destroy surrounding tissue and in particular phase will spread to other organs in the body.

The question is, how cancer cells can grow and run more faster than normal cells, which in the end they will be looking for blood-vessels or-lymphuntuk further spread to certain organs in the body (metastasis). There are three types of genes that are responsible for the process as above IE: evil genes (oncogenes), good genes (tumor suppressor genes) and those genes that function in other genes that repair damaged (mismatch-repair genes).
