We treat the majority of all skin cancer patients in the HUS area. The treatment of skin cancers is mainly surgical, and we also have the possibility to perform so-called Mohs surgery, or margin-controlled surgery. We treat skin cancer precursors with cryotherapy, photodynamic therapy (PDT), and cream treatments. We also have a carbon dioxide laser and a vascular laser for the treatment of congenital vessel abnormalities, among other things. Patients come to our outpatient clinic with a referral. ## [ Maisa Portal (opens in new window, links to another website) ](https://www.maisa.fi/maisa/Authentication/Login?lang=finnish) maisa.fi You can use our online services by signing in to the Maisa Portal.
