recurrence in muscle near breast?

[Sueb1]

Just wondering if anyone has had a recurrence in muscle. A CT scan showed what orig. was thought to be scar tissue near the orig. lumpectomy site, but a ultra-sound shows two shadows and now they are thought to be a recurrence. I go in for biopsy next week, but am pretty nervous. First I was told that it looked like a local recurrence, now it's being called a regional recurrence.
Thank you
