Numerous case-control studies have suggested a link between the oral contraceptive pill and liver cancer. The secular trends in liver cancer mortality rates for England and Wales from 1975 to 1992 were examined to determine whether an effect of the pill was apparent. Liver cancer mortality has remained constant in women in the age groups that have had major exposure to the pill.
众多病例对照研究表明口服避孕药与肝癌之间存在联系。对1975年至1992年英格兰和威尔士肝癌死亡率的长期趋势进行了研究，以确定避孕药的影响是否明显。在大量接触过避孕药的年龄组女性中，肝癌死亡率一直保持稳定。
