Excess occurrence of cancer of the oral cavity, lung, and bladder following cancer of the cervix.

The risk of developing a second cancer among white and black females with an initial cancer of the uterine cervix or corpus has been estimated based on the experience of the Charity Hospital of Louisiana Tumor Registry, a participant of the End Results Program of the National Cancer Institute. Observed second primary cancers were compared to expected numbers in order to obtain a direct estimate of risk. White females having an initial cancer of the cervix had a 5-to-6-fold excess risk of developing a subsequent cancer of the oral pharynx, lung or bladder during the first 5 years following their initial cancer with no excess risk for developing subsequent cancer of the breast or large intestine, but a slight excess risk for developing subsequent cancer of the ano-rectum. There was a 7% excess risk among both whites and blacks with initial cancer of the corpus uteri of subsequently developing another cancer.
