A biopsy is a medical procedure used to obtain a sample of tissue or cells from a specific area of the body for further examination and analysis. In dermatology, skin biopsies are commonly performed to diagnose and evaluate various skin conditions, such as rashes, lumps, moles, and skin cancers. This procedure helps dermatologists gain valuable insights into the underlying cause of skin abnormalities, allowing for accurate diagnosis and appropriate treatment. In this guide, we will explore skin biopsies, their types, benefits, considerations, and how they play a crucial role in dermatological evaluations.
