Impact of Osteopathic Manipulative Medicine on Sentinal Lymph Node Biopsy Dye and Tracer Uptake

The goal of this clinical trial is to learn if osteopathic manipulative medicine (OMM) will allow for more uptake of isosulfan blue dye and radiotracers used in sentinal lymph node biopsy (SLNB) compared to massage alone. SLNB is used to characterize the stage and spread of cancer cells in breast cancer patients. The main questions it aims to answer is: \- Does OMM + massage allow for greater uptake of isosulfan blue dye and radiotracer in the lymph nodes compared to current standard of practice of breast massage after isosulfan blue dye and radiotracer injection. Researchers will compare OMM + massage to current standard of practice of breast massage. Randomization: Patients will be randomized prior to surgical intervention as to which arm of the study they will be assigned to: Massage (current standard) vs OMM + Massage Massage: 9 minutes of circular massage over the nipple areolar complex to disperse isosulfan blue dye and radiotracer that were injected into the breast. Massage following injection is standard of care. OMM+ Massage: 5 minutes of massage as above and then will perform osteopathic techniques including 1 minute of each of the following: opening the thoracic inlet, pectoral traction, and axillary pump. Thoracic pump will be done for 2 minutes. Isosulfan blue dye and radiotracer will then be injected followed by massage as done in the current standard of practice. The injection and massage are performed as per standard of care.
