For example, cancer cells can make normal cells produce blood vessels to supply the tumor’s oxygen and nutrient needs as they grow. Cancer cells also do not mature and develop to perform highly specialized functions as normal cells do.Ĭancer cells can also “hide” from the immune system, which normally destroys and removes abnormal or damaged cells.įurthermore, cancer cells can also sometimes influence healthy cells, blood vessels, and molecules that nourish and surround tumors. Unlike regular, healthy cells, cancer cells can grow and divide at an uncontrollable and very high rate. It is these differences that allow cancer cells to form tumors that can cause organ damage, failure, and eventually death. There are several differences between cancer cells and normal cells. That said, some cancers form in the blood, and these typically do not create solid tumors. In many cases, tumors are solid masses of abnormal tissue.
