how long keep biopsy site covered
Keep the biopsy site clean and dry until it heals completely. Your stitches will be taken out 3 to 14 days after the biopsy, depending on the biopsy site. Adhesive bandages should remain in place until they fall off. This usually takes from 7 to 14 days. The biopsy site may be sore or bleed slightly for several days.
The biopsy site is then covered with a bandage or sterile dressing. Punch biopsy. After a local anesthetic is injected, a small, sharp tool that looks like a cookie cutter (punch) is placed over the lesion, pushed down, and slowly rotated to remove a circular piece of skin.
