A quick, in-office procedure to sample skin tissue for an accurate diagnosis.
Diagnostic Procedure
A skin biopsy removes a small sample of skin tissue so it can be examined under a microscope, providing a definitive diagnosis for growths, rashes, or other changes that can't be identified by appearance alone. It's one of the most common and important diagnostic tools in dermatology.
Used to diagnose suspicious moles, possible skin cancers, unexplained rashes, and other skin changes that need a clear answer before treatment can be planned.
Performed under local anesthesia, using a shave, punch, or excisional technique depending on the depth of tissue needed. The sample is sent to a lab, with results typically back within one to two weeks.
Most biopsy sites heal within one to two weeks with simple wound care; some techniques require a stitch or two that's removed shortly after.
Myth: Getting a biopsy means you definitely have cancer. Fact: A biopsy is simply the step that provides a clear answer -- most biopsied spots turn out to be benign.
If your dermatologist has identified a spot that can't be confidently diagnosed by appearance alone, a biopsy provides the certainty needed to plan the right next step.
