The study is a prospective multi-centered cohort study designed to determine the safety and efficacy of AlloMax in immediate expander-based breast reconstruction. Specifically, the study is designed to determine if sterility of human acellular dermal matrix results in a lower incidence of infection and seroma. The study will determine if gamma radiation, as a method of terminally sterilizing human acellular dermal matrix, has a negative impact on graft incorporation into the host tissue.


Inclusion Criteria: - Patients having immediate breast reconstruction with tissue expanders - Unilateral or bilateral reconstructions - Ages 25 - 65 - All breast cancer stages and types Exclusion Criteria: - BMI > 35 - Active smokers - Diabetics - History of radiation or planned radiation - Immunocompromised patients
