What two specific effects are believed to be caused by exposure to an unborn child?

The belief that exposure to certain factors during pregnancy can lead to developmental delays and childhood cancer stems from research into various environmental toxins, maternal health, and teratogens. Developmental delays can arise from factors such as exposure to harmful substances, infections, or maternal conditions that interfere with normal fetal development. This can affect cognitive, physical, and emotional development in the unborn child.

Childhood cancer is another serious concern linked to fetal exposure. Studies have suggested that certain prenatal exposures, including environmental pollutants and specific medications, may increase the risk of developing cancers such as leukemia during childhood. This connection emphasizes the critical nature of maternal health and environmental conditions in influencing long-term outcomes for children.

This choice effectively captures two significant and serious risks associated with prenatal exposure, linking both developmental concerns and the risk of cancer, which are key discussions in maternal and child health research.
