Laser surgery uses a wavelength of light that is focused in a narrow beam. This high-intensity light is used to shrink or destroy skin cancers or pre-cancers (actinic keratosis). With lasers, there is usually less bleeding, swelling, and scarring. Healing is quicker, and you are less likely to get an infection.
Several different types of lasers are used to treat skin cancers, including the carbon dioxide (CO2) laser.
The wound will be painful for a few days after laser surgery. Healing usually occurs in 2 to 4 weeks.
Be sure to follow your doctor's instructions for caring for your wound.
Laser surgery may be used to treat an actinic keratosis, and in rare cases, low-risk basal cell carcinoma.
Laser surgery is an effective treatment for actinic keratosis.footnote 1
If laser surgery is used to treat basal cell skin carcinomas, it should only be used for low-risk cancers.footnote 2 While laser surgery may work well for these types of cancer, it may not remove all of the cancer and prevent it from coming back.
There is a slight risk of infection associated with laser surgery. Be sure to call your doctor if you have any of these signs of infection:
Laser surgery usually isn't used for basal cell carcinoma. With laser surgery, it isn't possible to make sure all the cancer cells are gone. Other types of surgery, such as excision or Mohs, remove tissue and can check to make sure all the cancer is gone.
