"The cancer-causing potential of fetal exposure to carcinogens can vary substantially, a recent study suggests, causing different types of problems much later in life depending on the stage of pregnancy when the fetus is exposed." The article goes on to suggest what kind of doses are most damaging later on in life for individuals. Vulnerability during the fetal stage to carcinogens is not known in detail, yet. Obviously, carcinogens are not preferred during a pregnancy.
