Had core biopsy a week ago which came back benign but there's a hard area from the needle entrance all the way to biopsy site, and bruising. normal?

See your doctor: Where was biopsied? Likely a normal reaction as your body attempts to repair the tract. Would discuss with your doctor.

Probably normal: Perhaps you had some bleeding in the site of the biopsy and what you are feeling is either a blood clot or perhaps scarring. Try using warm compresses for now, and once the bruising is gone you can gently massage the area.

Biopsy: Its normal to have some bruising and discomfort after a biopsy. This should gradually subside. If symptoms persist consult your doctor. Take care!

Hematoma: It is most likely a post biopsy hematoma: swelling and blood clot from the procedure. It is not unusual and should go away in a week or two. Sometimes they can get infected in which case you need to call the dr.
