Can laser mole removal cause cancer to the mole?

Question

i am planning on getting laser removal for my flat facial moles, i checked with the dermatologist and they are benign. but i am worried that if not all of the mole was lasered, it can grow back and become cancerous, is that possible?

When considering laser mole removal, it is important to understand the potential risks and outcomes. Laser removal is generally safe for benign moles, as confirmed by your dermatologist. However, it's crucial to note that laser treatment does not allow for histological examination, which means the mole's tissue cannot be analyzed for any atypical or malignant cells.

While the procedure itself does not cause cancer, there is a theoretical risk that if a mole is not fully removed and had any atypical cells, those cells could potentially change over time. This is why it is essential to ensure that the moles are thoroughly evaluated by a dermatologist before removal to confirm they are entirely benign.

If you have any concerns about the potential for moles to become cancerous, you might consider surgical excision, which allows for complete removal and biopsy. Always discuss the benefits and risks with your dermatologist to determine the best approach for your specific situation. Your dermatologist can provide guidance tailored to your individual needs and ensure that you are making an informed decision.
