Patient Experiences With the COVID-19 Vaccination After Breast Cancer Treatment
This study aims to elicit patient experiences, choices, and side effects associated with the COVID-19 vaccine after breast cancer surgery. Lymph node swelling is a known and common side effect of both the Moderna and Pfizer COVID-19 vaccines. This is the body's normal reaction to the vaccine. It is worrisome that lymph node swelling after the vaccine mimics that found in breast cancer which has spread to the lymph nodes. This side effect will cause worry and anxiety amongst patients as a result. For patients who have had lymph node removal (axillary lymph node dissection or sentinel lymph node biopsy) and are at risk of lymphedema, the investigators are concerned that the lymph node swelling may tax the lymphatic system and incite lymphedema in those at risk or worsen it in those with BCRL. Fear of lymphedema is high in this population and the investigators need to better understand what risk, if any, lymph node swelling after the COVID-19 vaccine imparts to BCRL risk.
