Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary Objective: To test the effectiveness of four alternative approaches to topical anesthesia on pain associated with radiotracer injection for women diagnosed with breast cancer undergoing sentinel lymph node mapping.

Secondary Objectives:

1. To assess patient satisfaction with pain control modality for radiotracer injection.
2. To identify barriers to implementation of the different pain control interventions.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Ice Pack

Ice will be placed on the breast prior to radioactive tracer injection (usual treatment)

Group Type ACTIVE_COMPARATOR

Ice pack

Intervention Type OTHER

Ice cools the skin and can provide some numbing for pain.

Lidocaine Patch

A lidocaine patch (4% topical) will be placed on the breast for at least one hour prior to radioactive tracer injection

Group Type EXPERIMENTAL

Lidocaine patch

Intervention Type DRUG

Lidocaine is a local anesthetic.

Buzzy(R)

A vibrating distraction device (Buzzy(R)) and ice will be placed on the breast prior to radioactive tracer injection.

Group Type EXPERIMENTAL

Buzzy(R)

Intervention Type DEVICE

Buzzy provides non-invasive pain relief by vibrating and cooling the skin which distracts from pain sensations.

Ice pack

Intervention Type OTHER

Ice cools the skin and can provide some numbing for pain.

Lidocaine Patch and Buzzy(R)

A lidocaine patch (4% topical) will be placed on the breast for at least one hour prior to radioactive tracer injection. This will be removed and a vibrating distraction device (Buzzy(R)) and ice will be placed on the breast just prior to radioactive tracer injection.

Group Type EXPERIMENTAL

Lidocaine patch

Intervention Type DRUG

Lidocaine is a local anesthetic.

Buzzy(R)

Intervention Type DEVICE

Buzzy provides non-invasive pain relief by vibrating and cooling the skin which distracts from pain sensations.

Ice pack

Intervention Type OTHER

Ice cools the skin and can provide some numbing for pain.

* radiotracer injection occurs on the same day as sentinel lymph node surgery

Exclusion Criteria

* males
* pregnancy
* local anesthetic allergy or active use of the following medications:

* Abametapir (risk X)
* Conivaptan (risk X)
* Fusidic Acid (risk X)
* Idelalisib (risk X)
