A skin biopsy treatment involves obtaining a sample of skin according to the size and location of skin lesion in order to diagnose diseases of the skin, such as those caused by skin tumors, other types of growths, infections, or other skin conditions.

There are various methods of performing skin biopsy depending on the size of lesion, suspected clinical diagnosis and site of lesion. A biopsy of a lesion of the skin can help your doctor tell the difference between a skin cancer and a benign, or noncancerous, lesion. The skin sample obtained during a biopsy is sent to a laboratory for examination under a microscope.
