title: [Characterizing cancers in elderly patients].
abstract: High differentiation, slow growth and relatively well delineated growth pattern have been pointed out as characterizing cancers in the elderly. Although, there are not infrequently exceptions, these features encourage more drastic access in treating cancers of the old age. Factors inducing such features are discussed from the viewpoint of experimental carcinogenesis.
