Correlation between cancers of the uterine cervix and penis in China

A national survey of cancer mortality in the People's Republic of China during 1973--75 revealed concurrent geographic variation for cancers of the uterine cervix and penis, including clustering of both tumors in central parts of the country. The findings are consistent with recent reports from other countries that the cancers tend to aggregate in spouses and with the hypothesis of an etiologic factor in common.
