We know very little on how to prevent cancer in children and youths, though a number of environmental exposures (e.g. pesticides, extremely low frequency electric and magnetic fields) have been suspected of increasing the risk of childhood leukemia and lymphomas, while we have good evidence that exposure to ionising radiation (X-rays of the pelvis of the mother) of the fetus in pregnancy increases the risk of childhood leukemia. However, we do know that the lifestyles adopted by children and youths drastically influences the risk of cancer in them when they are adults. Examples include adoption of habits of healthy eating, exercise, not smoking. A relatively new example is exposure to Radiofrequency radiation (RFR) from cell phones and other devices. Prevention of RFR exposure to children and youths will, we believe, prevent brain cancer at older ages (as well as some brain cancers in youths), while adoption of healthy eating, regular exercise and giving up smoking will have a major effect on preventing cancer at older ages, providing these approaches to a healthy lifestyle are adopted relatively early in life, e.g. the dramatic effect of ceasing smoking before the age of 40.
