* Breast cancer eligible for primary surgery

* Patients with a history of autoimmune-related hypothyroidism who are on thyroid replacement hormone are eligible for the study.
* Patients with controlled Type 1 diabetes mellitus who are on an insulin regimen are eligible for the study.
* Patients with eczema, psoriasis, lichen simplex chronicus, or vitiligo with dermatologic manifestations only (e.g., patients with psoriatic arthritis are excluded) are eligible for the study provided all of following conditions are met:
