A Skin Biopsy is a procedure in which a sample of skin tissue is removed, processed, and examined under a microscope. Several different methods may be used to obtain a skin sample, depending on the size and location of the abnormal area of skin, called a skin lesion.
Skin Biopsies most often are done to diagnose skin cancer, which may be suspected when an abnormal area of skin has changed color, shape, size, or appearance or has not healed after an injury. Skin cancers are the most common type of cancers. Early diagnosis of a suspicious skin lesion and skin biopsy can help identify skin cancers and lead to early treatment.
Why It Is Done?
A skin biopsy is done to diagnose a:
- Skin condition (if it is not already clear what the condition is), such as psoriasis.
- Disease, such as skin cancer.
- Bacterial or fungal skin infection.
