With liquid nitrogen the skin can be treated. Tissue will be frozen up to minus 80 degrees Celsius. The skin turns white during treatment and red after treatment. Due to the temperature there will be local skin damage. During the next day’s crust or sometimes blister formation can occur. After 1 week the skin is healed.
Efudix / Aldara treatment
With special cremes the affected skin can be treated several times during 2-6 weeks. During this treatment period the skin cells will be destroyed, and after stopping the application the skin will heal within 1 week.
Usually skin cancer is excised under local anesthesia. Therefore the healthy skin around the skin cancer is marked and then locally anesthesia. The skin cancer is cut out and wound edges are sued together. Stitches will be removed after 7-14 days. The skin specimen will be checked under the microscope in order to evaluate if the cutting borders are free of skin cancer.
Superficial skin cancers and pre cancers can be treated with photodynamic therapy. A creme will be applied to the afflicted areas of the skin (deltaminolaevulinic acid) and be kept on the skin for 3 hours. During this time the cream penetrates into the cancer cells, but it rarely penetrates healthy skin cells. After 3 hours the cream is removed and the skin area is exposed to red wavelength of light during 20 minutes. The interaction of light and activated skin cells makes that the skin cells degenerate. The following days some crust formation is visible and within 1 week the skin is healed.
For special cases of skin cancer we uses the MOHS technique. It is an operation method where the skin cancer gets excised as described above. But the pathological work up is different in this technique. All of the wound edges will be investigated under the microscope in order to be sure that no tumor cell is left behind. This technique is used for skin cancer in the face where the biopsy showed a cancer type that is difficult to distinguish from healthy skin cells.
