The epidemiology of bladder cancer in West Yorkshire. A preliminary report on non-occupational aetiologies

Abstract
A preliminary report of a large case-control study on the epidemiology of bladder cancer in West Yorkshire is presented. Several aspects of the life-style of cases and controls are investigated. These show statistically significant differences between cases and controls in smoking cigarettes and some inconsistent differences for saccharin consumption and coffee drinking. Alcohol consumption proved to be the same in the case and control groups.
