Children, and the environment and cancer

Much of the research on the links between the environment and cancer has focused on exposure in adults. There hasn’t been a lot of research looking at the impact of these links early in life – either before birth or in babies and young children. Finding out about this is important because researchers believe that children may be more vulnerable to substances that may increase the risk of cancer, cause birth defects or interfere with the normal hormonal system in the body. There are several reasons for this:

  • Children may absorb more environmental contaminants because they breathe, eat and drink more than adults relative to their body weight.
  • Children, especially infants and toddlers, sit more often on the ground and crawl to areas where adults typically don’t go. As they explore, they often put their hands and fingers into their mouths.
  • There are periods during normal human development when exposure may pose more harm than during other parts of life. For example, the risk of developing cancer is greater among children exposed to radiation than it is for adults exposed to the same amount of radiation. 
  • Pesticides

    Some regions in Canada have by-laws banning the use of cosmetic pesticides. Using pesticides on our lawns and gardens to keep away pests and weeds may harm the health of our families, children and pets.

    Your child’s exposure to pesticides should be reduced to the lowest level possible. If you need to control pests in your lawn or garden, try to use safer options.

    Tips to reduce exposure

  • Household cleaners

    Household cleaners may leave behind residues that may be toxic to small children who are more sensitive to their ingredients. Currently in Canada, manufacturers of consumer products such as household cleaning items do not have to list ingredients, but they may list this information on their products voluntarily. If you ask for this information, manufacturers should be able to offer it, making it easier for you to choose to use the product or not.

Some cancers, such as thyroid and testicular, have survival rates of over 90%. Other cancers, such as pancreatic, brain and esophageal, continue to have very low survival rates.
