Sweat duct tumor treatment methods include traditional dermabrasion laser, electrocautery, chemical cauterization, cryotherapy, surgical excision, etc., and the newer carbon dioxide microdot shuttle laser. However, dermabrasion laser, electrocautery, cryotherapy, and chemical cauterization cannot destroy the deep root of the lesion, so there is a higher possibility of recurrence, and there may be scarring after-effects. In order to completely remove sweat duct tumors, surgery is needed to remove the root of the sweat duct tumor lesion as well, in order to permanently eradicate sweat duct tumors, but it will also leave scars, and if the number of sweat duct tumors is too large, the numerous surgical scars will cause new problems. Currently, the newer and more effective treatment method is to use CO2 micropoint shuttle lasers to gradually remove the existing sweat duct tumor foci without scarring, requiring multiple treatments. The more treatments, the fewer foci that remain and the less noticeable they will be, and the lower the chance of recurrence in the original location.
