Actinic keratosis (AK) is a pre-cancerous skin condition caused by long-term exposure to ultraviolet (UV) radiation. It usually appears as scaly, crusty patches on the skin. It is important to monitor any suspicious AK lesions and to consider biopsy if the lesions persist or worsen.
When Should Actinic Keratosis Be Biopsied?
Generally, a biopsy of any suspicious AK lesions is recommended. This is especially true for lesions that are larger than 2 cm, have an unusual color or shape, or have not responded to other treatments. A biopsy can help to determine if the lesion is cancerous or precancerous and can help guide further treatment plans.
What Are the Different Types of Biopsy?
There are a few different types of biopsies that may be used to diagnose actinic keratosis. A shave biopsy involves shaving off the lesion with a small blade. An excisional biopsy involves surgically removing the lesion with a scalpel. A punch biopsy is similar to an excisional biopsy, but a core of tissue is removed instead of the entire lesion. Finally, a brush biopsy involves using a brush to collect cells from the lesion.
What Are the Risks of Biopsy?
The risks of biopsy are generally minimal. However, there may be some slight bleeding, scarring, or temporary discoloration of the skin. Infection is also a possible risk, though this is rare. It is important to speak to a doctor before having a biopsy to ensure that the procedure is right for you.
