Macroscopic and histopathological tumor findings and survival rates were obtained from the patient records.

We analyzed the relationship between tumor size on mammography in each category and histopathological tumor size.

In the breasts with palpable tumors, we compared palpated tumor size and histopathological tumor size according to the mammographic subtypes.

Background: Histopathological tumor regression may have an important prognostic impact in addition to the UICC-TNM classification system.
