title: Common variable immunodeficiency and breast cancer.
abstract: We describe two women with early onset breast cancer (at ages 31 and 38) who were found to have common variable immunodeficiency (CVID). Both women had a history of frequent and unusual bacterial infections. The incidence of breast cancer in young women and of CVID are both low, and the coincident diagnosis in two patients from a relatively small population base suggests the possibility of a pathophysiologic or causal relationship.
