At one year, and there are varieties that can tarnish.
The treatment of this cancer depends on where it is and its size and type, and the age and general condition. Surgical treatment is more effective, especially cryosurgery and Mohs surgery. The electrofulguration, cryosurgery, 5-fluorouracil cream 5% imiquimod, interferon alpha 2B and oral retinoids, which seem to stop the progression of these carcinomas.
