Biochemistry pathway of normal and cancer cell

Normal cells will separate within the presence of a chemical signal like as "growth factor" (GF). Other molecular signals from within cells or from their environment could cause cells to halt division. In healthy tissue, damaged cells are eliminated through programmed cell death (apoptosis) and are replaced while neighboring cells undergo mitosis. A mutagen, like as UV light, may lead to mutations within cellular DNA. Mutated cells along with damage in critical fields of their DNA can undergo mitosis while or not growth factor is present.
