This is an observational study that tracks how quickly and completely a specific nerve block called an ESP block (erector spinae plane block) numbs the chest area during breast cancer surgery. Researchers want to understand exactly when the pain relief starts working and how much of the surgical area it covers, so doctors can better time surgery and improve comfort for patients having breast procedures.
Breast surgery is complex because the breast receives nerve signals from many different sources, making it hard to numb completely. By carefully measuring how this nerve block works in real patients, doctors hope to improve pain control during and after surgery, help you recover faster, and prevent long-term pain problems that sometimes develop after breast procedures.

If you join this study, doctors will perform the ESP nerve block injection as planned for your surgery, but they will carefully measure and document exactly when the numbing sensation spreads across your chest and how complete the pain relief becomes. This is purely observational — you won't receive any experimental medication, just careful monitoring of the standard nerve block technique your surgeon was already planning to use. The study involves no extra procedures beyond what you'd normally receive for breast surgery.
