The nucleotides in genes themselves don’t have to be changed to increase susceptibility to cancer. Instead, genes – which code for proteins in their “on” state – can be turned “off” or “on” by what are called epigenetic changes. Since the proteins that are created can alter how our bodies process information and nutrients, and maintain the right balance, these effects can profoundly affect health. Epigenetic changes can occur as a result to exposure to chemicals and radiation, and exposures in the womb or early childhood may affect health later in life.
