title: 'Leaving a mark'.
abstract: Biopsies by various means do have a risk of seeding tumour cells into the biopsy track. Even with fine needle and trocar techniques this has been proven to occur. By excising the biopsy track at the time of surgery this risk can be reduced. With needle and trocar techniques there might be little evidence of the puncture when the time of surgery takes place. We advocate using Indian ink to mark the biopsy site.
