Tests and diagnosis

By Mayo Clinic staff

In addition to taking a complete medical history and checking the affected area of skin, your doctor may remove a small skin sample (biopsy) for examination under a microscope. Often, the biopsy is sent to a pathologist who has special expertise in diagnosing skin samples.

A suspected squamous cell carcinoma is often biopsied by shaving off the top layers of skin with a surgical blade. Tumors that have spread deeper into the skin may be partially or completely removed (incisional or excisional biopsy). Because all biopsies are likely to leave a small scar, talk to your doctor about the types of biopsies and their potential for scarring before having the procedure.
