What is a biopsy?
Last updated September 3, 2026.
A biopsy is the removal of a small piece of tissue for lab examination - the definitive answer to questions scans and blood tests can only raise. Types range from fine-needle aspiration and core needle biopsies under local anesthesia, through skin punch and shave biopsies, to endoscopic and surgical samples. Most are outpatient, minutes long, with a few days of mild soreness; the pathology report drives everything that follows.
What to do
- Ask which type and why. Needle, scope, or surgical - the choice follows the tissue's location.
- Plan the logistics. Most need no downtime, but sedation for some types means a ride home.
- Follow wound care. Keep the site clean and bandaged; report spreading redness, pus, or fever.
- Get the report explained. Benign, precancer, and cancer each start a defined next step - have the conversation.
