"The health risks of the Pill outweigh by far the risks of pregnancy and childbirth to a woman's health, and any claim to the contrary is based on erroneous comparisons between healthy women on the Pill and women who do not receive normal care during pregnancy. A precondition for obtaining the Pill is routine medical care and checkups. For example: if such a woman on the Pill is diagnosed as "precancerous," or if some other side effect is exhibited, she has the advantage of early detection. However, many pregnant women do not receive routine medical care. A clearer picture of the safety of the Pill compared to the safety of pregnancy would be made if healthy women receiving routine medical care during pregnancy and delivery were compared with women receiving routine medical care while taking the Pill."
