Official title

Optimizing Topical Pain Control for Breast Cancer Patients Undergoing Pre-operative Radiotracer Injection for Sentinel Lymph Node Mapping

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to compare the effectiveness four different pain treatments for the injection of radioactive tracer that women with breast cancer receive for sentinel lymph node biopsies. This study will include women who have been diagnosed with breast cancer and who will be undergoing sentinel lymph node biopsy with a standard injection of radioactive tracer before surgery. A participant's active participation will take place on two separate occasions. In the first occasion, a participant will complete a brief pain assessment on the day of enrollment. The rest of a participant's active participation will take place on one day (the day of surgery) and last approximately 20 minutes, after which active participation will end.
