After you've gotten a skin biopsy at our Bedford, TX practice, it is highly recommended that you avoid swimming, hot tubs, and natural bodies of water until your treatment area heals to help reduce your risk of infection. Generally, it takes approximately 7 – 10 days for the wound from a skin biopsy to heal. Dr. Calvin Williams will provide specific instructions for when it is safe to resume water activities, as it may depend on the size, location, and type of skin biopsy that was performed.
