Actinic keratosis (AK) is a condition that is characterized by scaly, crusty patches on the skin. AK is often caused by sun exposure and can be seen on areas of skin that are most often exposed to the sun, such as the face, ears, hands, arms, and scalp. In some cases, AK can develop into skin cancer, so it is important to have it checked by a doctor. A biopsy is a way of diagnosing AK, as it can help determine if the condition is cancerous.
When Should I Have a Biopsy for Actinic Keratosis?
If you have any of the following signs or symptoms, it is important to see a doctor right away:
• Red or pink patches on the skin
• Patches that are scaly, crusty, or raised
• Patches that are itchy, tender, or painful
• Patches that do not heal
If your doctor suspects that you have AK, they may recommend a biopsy. This is a procedure in which a sample of the skin is taken to be examined under a microscope. A biopsy can help determine if the patch is cancerous or not.
What Will Happen During the Biopsy?
The biopsy procedure is usually done in a doctor’s office or clinic. The area of skin that needs to be examined will be numbed with a local anesthetic. Then, a sample of the tissue will be taken with a small scalpel or needle. The sample will be sent to a laboratory to be examined under a microscope.
Your doctor will be able to give you more information about the biopsy procedure and what to expect.
What Happens After the Biopsy?
After the biopsy, your doctor will let you know the results. Depending on the results, you may need to have further treatment. If the biopsy indicates that the AK is cancerous, your doctor may recommend cryotherapy, topical chemotherapy, or laser therapy. If the AK is not cancerous, your doctor may recommend topical creams or ointments to help reduce the appearance of the AK.
It is important to have any suspicious lesions on the skin checked by a doctor. A biopsy can help diagnose actinic keratosis and determine if any further treatment is needed.
