I had my biopsy thursday morning and finally worked up the nerve to shower and feel around the incision/biopsy site saturday night. It's still tender like a bad bruise, but the lump got really big. It was kidney bean sized and now it's large walnut sized. Could that be a hematoma, or would a hematoma hurt or throb? Or is there normally swelling associated with a biopsy like that? It was an ultrasound guided HUGE needle biopsy using Mammotome if that helps. Thanks for any info, it's hard to find many answeres on other sites.
