[Genetics and human cancers: methods of study (author's transl)].
The role of hereditary factors in the etiology of cancer is difficult to prove. However, one may precise a hereditary relationship in those cancers which are either transmitted as a monofactorial trait, or secondary to a hereditary disease, or linked to a genetic marker. Most often, it is necessary to fall back on familial investigations, which may sometimes indicate an excess of familial cases. However, a familial concentration of certain cancers may also be due to hereditary factors, as well as to a common environment.
