Breast Care Team

Obtaining your cancer care from a medical team that treats a high volume of patients with your specific cancer type has its advantages - namely, successful patient outcomes. Studies show that physicians who treat large numbers of patients with a specific disease achieve better patient outcomes.

Hoag’s expert medical team and higher than national figure survival rates are just two reasons why the majority of patients diagnosed at Hoag remain at Hoag for treatment. Hoag also has specialized plastic surgeons on staff who are experts in breast reconstruction for patients who undergo mastectomy.
