[Incidence of locally confined growth of carcinoma of the breast (author's transl)].

In 220 cases of breast carcinoma with an anatomical size of less than 2 cm metastases outside the primarily affected quadrant could be demonstrated in the remaining breast in 23.6% of cases (n = 52). Axillary lymph node metastases were present in 3.93% (n = 86). With a tumour size up to 0.5 cm neither metastases in remaining breast tissue nor lymph node metastases could be found. With a tumour size of 0.6 to 1.0 cm only 32 out of 51 cases (62.7%) could be considered to be locally confined. In tumours between 1.1 and 2 cm there was no spread demonstrable in remaining breast tissue or axillary nodes in 70 out of 164 cases (42.7%).
