Squamous cell carcinoma (SCC) of the breast is an uncommon breast neoplasm. There are limited data about its epidemiology and few studies focusing on outcomes. This study aims to identify specific characteristics of patients with breast SCC, investigate its natural history, and determine its long-term prognosis. One hundred and seventy-seven cases of SCC of the breast were identified in the California Cancer Registry from the years 1988 to 2006. At the time of diagnosis, 53 per cent of patients had localized disease, 32 per cent of patients had regional lymph node or locally advanced disease, and 8 per cent of patients had distant disease. The relative cumulative survival of patients was 68.1 per cent at 5 years and 60.2 per cent at 10 years. This is significantly worse than the relative cumulative survival of patients with all other invasive breast tumors during the same time period. Squamous cell carcinoma of the breast is a rare and aggressive disease, and it has significantly worse prognosis than other nonsquamous cell tumors of the breast. Clinicians should be aware of the aggressive nature of the tumor when counseling patients.
