The elderly (aged 70 years or more) constituted 201 (37%) of 548 first‐time admissions to a single institution for breast cancer between 1976 and 1985. The pattern of disease was studied and contrasted with that seen in younger patients (less than 70 years old). Currently, 5000 new breast cancers are diagnosed in Australia each year. It is projected that the proportion of new breast cancer patients who are elderly will rise from 37 to 60% by the year 2031. In general, the disease was similar to that seen in younger patients. Minor histological differences occurred and there were tendencies towards late presentation and clinically less aggressive disease. Tumour size, the presence of metastases and UICC staging were useful predictors of outcome but nodal status and hormone receptor levels did not discriminate. An unexpected finding was the relative longevity of elderly patients with breast cancer. The stage‐specific 5‐year survival rates (UICC stages: I —73%; II — 65%; III —42%; IV — 10%;) did not differ significantly from those seen in younger patients.
