In simplest terms it is uncontrolled cell division when they are (cid:498)packed(cid:499) tightly together (cancerous) growth spread out in all directions. Contact inhibition fails to occur in cancer cells. In contrast, cancer cells continue to divide uncontrollably. Excessive cell division may also produce a benign growth, in which cells are contained within a single encapsulated mass called a benign tumor. They only cause limited damage in the area of the tumor. Cells break out of the capsule (or even lack a capsule) and invade other tissues. A cancerous growth often undergoes metastasis where the cells break away and.
