WebMar 19, 2024 · All cancer cells have DNA mutations, and it is the carcinogens that cause the mutations. Carcinogens cause mutations by damaging the way the cell repairs DNA or makes proteins. If the cancer cell is not able to repair this DNA damage, then it will keep dividing to make new cells and will pass the mutation on to all the new cells that are made. WebIn healthy tissues, the processes of mitosis and differentiation are tightly regulated. This is how the body ensures that only the correct number of cells is produced. The body has 2 methods for controlling the rate of cell proliferation: Growth factors; Contact inhibition; stimulate mitosis and/or cellular differentiation.
