Cancer occurs when a cell's gene mutations make the cell unable to correct DNA damage and unable to commit suicide. Similarly, cancer is a result of mutations that inhibit oncogene and tumor suppressor gene function, leading to uncontrollable cell growth. Carcinogens Carcinogens are a class of substances that are directly responsible for damaging DNA, promoting or aiding cancer.
Cells â except for cancerous ones â cannot reproduce forever. When aging cells stop dividing, they become âsenescent.â Scientists believe one factor that causes senescence is the length of a cellâs telomeres, or protective caps on the end of chromosomes. Every time chromosomes reproduce, telomeres get shorter. As telomeres dwindle, cell division stops altogether.
