THE ASSOCIATION OF ORAL CONTRACEPTION WITH KIDNEY CANCER, COLON CANCER, GALLBLADDER CANCER (INCLUDING EXTRAHEPATIC BILE-DUCT CANCER) AND PITUITARY-TUMORS

This paper reviews the evidence for a relationship between oral contraceptive use and certain neoplasms: cancers of the kidney, colon and gallbladder (including the extrahepatic bile ducts) and tumours (benign or malignant) of the pituitary. Special reference is made to controlled epidemiological studies, both case-control and cohort. There is no convincing evidence that oral contraceptive use is causally related, either negatively or positively, to any of the tumours studied.
