Abstract
Report of a topographical study on 12 cases of breast cancer designed to establish whether all the areas of a given tumor had the same sex chromatin, this being essential for the determination of tumoral sex to be a valid therapeutic guide. The results show that, although there may be variations in the number of nuclei with sex chromatin, the variations are not so great as to alter the tumoral sex in a given tumor. The determination of tumoral sex on a single tumor fragment is therefore valid.
