Overview
Epidemiological risk factors for a disease can provide important clues as to the etiology of a disease. The first work on breast cancer epidemiology was done by Janet Lane-Claypon, who published a comparative study in 1926 for the British Ministry of Health of 500 breast cancer cases and 500 control patients of the same background and lifestyle.[citation needed] Although many epidemiological risk factors have been identified, the cause of any individual breast cancer is often unknown. In other words, epidemiological research informs of the patterns of breast cancer incidence across certain populations, but not in a given individual. Approximately 5% of new breast cancers are attributable to hereditary syndromes, while no etiology is known for the other 95% of cases.[1]
