[Mastopathy associated with early breast cancer].
Using 436 cases of infiltrating ductal carcinoma less than 2.0 cm in diameter mastectomized at the Cancer Institute Hospital, Tokyo, during 9 years from 1965 to 1973, association of mastopathy with breast cancer were analysed. Out of 436 cases, 128 (29.4%) were associated with mastopathy, and the association of mastopathy varied according to histologic type of breast cancer. The highest incidence was observed in carcinoma of papillotubular prototype and the lowest in carcinoma of medullary tubular prototype. Pure scirrhous carcinoma came between them. No correlationship was recognized between the grade of scirrhous stromal infiltration and incidence of mastopathy.
