What You Need To Know About™ Skin Cancer

Diagnosis

If you have a change on the skin, the doctor must find out whether it is due to cancer or to some other cause. Your doctor removes all or part of the area that does not look normal. The sample goes to a lab. A pathologist checks the sample under a microscope. This is a biopsy. A biopsy is the only sure way to diagnose skin cancer.

You may have the biopsy in a doctor's office or as an outpatient in a clinic or hospital. Where it is done depends on the size and place of the abnormal area on your skin. You probably will have local anesthesia.

There are four common types of skin biopsies:

  1. Punch biopsy: The doctor uses a sharp, hollow tool to remove a circle of tissue from the abnormal area.
  2. Incisional biopsy: The doctor uses a scalpel to remove part of the growth.
  3. Excisional biopsy: The doctor uses a scalpel to remove the entire growth and some tissue around it.
  4. Shave biopsy: The doctor uses a thin, sharp blade to shave off the abnormal growth.

You may want to ask your doctor these questions before having a biopsy:

  • Which type of biopsy do you recommend for me?
  • How will the biopsy be done?
  • Will I have to go to the hospital?
  • How long will it take? Will I be awake? Will it hurt?
  • Are there any risks? What are the chances of infection or bleeding after the biopsy?
  • What will my scar look like?
  • How soon will I know the results? Who will explain them to me?


Dictionary Terms

biopsy (BY-op-see)
The removal of cells or tissues for examination by a pathologist. The pathologist may study the tissue under a microscope or perform other tests on the cells or tissue. There are many different types of biopsy procedures. The most common types include: (1) incisional biopsy, in which only a sample of tissue is removed; (2) excisional biopsy, in which an entire lump or suspicious area is removed; and (3) needle biopsy, in which a sample of tissue or fluid is removed with a needle. When a wide needle is used, the procedure is called a core biopsy. When a thin needle is used, the procedure is called a fine-needle aspiration biopsy.
