{{Main|Lasers in cancer treatment}}
[[Laser]] therapy uses high-intensity light to treat cancer by shrinking or destroying tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers that are on the surface of the body or the lining of internal organs. It is used to treat basal cell skin cancer and the very early stages of others like cervical, penile, vaginal, vulvar, and non-small cell lung cancer. It is often combined with other treatments, such as surgery, chemotherapy, or radiation therapy. [[Laser ablation|Laser-induced interstitial thermotherapy]] (LITT), or interstitial laser [[Laser coagulation|photocoagulation]], uses lasers to treat some cancers using hyperthermia, which uses heat to shrink tumors by damaging or killing cancer cells. Laser are more precise than surgery and cause less damage, pain, bleeding, swelling, and scarring. A disadvantage is that surgeons must have specialized training. It may be more expensive than other treatments.<ref name="NIHlaser">{{cite web|url=https://www.cancer.gov/about-cancer/treatment/types/surgery/lasers-fact-sheet|title=Lasers in Cancer Treatment|date=13 September 2011|publisher=National Institutes of Health, National Cancer Institute|access-date=15 December 2017}}{{PD-notice}}</ref>
