The newborn period (also known as the postnatal period) is the period immediately after birth. Most organs continue their development during this period, while the breast goes into a dormant phase.
Some studies have found EDCs in breast and formula milk. The mother may be exposed to EDCs from the environment or in her diet. The chemicals may then enter the breast milk and possibly reach the baby. EDCs may also enter formula milk from plastic bottles or packaging. For this reason, bisphenol A (BPA) was banned from baby bottles in 2011. Formula milk is also highly regulated and there are strict criteria to prevent contamination from pesticides.
More research is needed in this area to understand the effects of EDC exposure on babies.
Breast Cancer UK supports breastfeeding. You can read more about breastfeeding and its many benefits here. If you are breastfeeding, you can limit your exposure to chemicals by choosing organic food and checking the ingredients of cosmetics and other personal care products before using them.
Children may be exposed to EDCs, including a group called phthalates, from plastic toys, especially when they put them in their mouths. Phthalates can also accumulate in dust to which children are exposed to when crawling around. For these reasons, the exposure to phthalates in children may be higher than in adults.
A possible link between the effects of EDC exposure in the newborn and the development of the brain has been noted in some studies. However, more research is needed in this area.
So far, studies have been limited. More research is needed to study if EDC exposure in newborns and children increases breast cancer risk later in life.
