Skin of An Cancer Overview
If treated early, most skin cancers are curable. Biopsy any skin lesion, whether appearance is typical for cancer or atypical, that enlarges or persists longer than expected.
Routine screening for skin cancer is by patient self-examination, physician examination, or both. Because many skin cancers seem to be related to ultraviolet UV exposure, a number of measures are recommended to limit exposure. Seeking shade, minimizing outdoor activities between 10 am and 4 pm when sun's rays are strongest , and avoiding sunbathing and the use of tanning beds. Current evidence is inadequate to determine whether these measures reduce incidence or mortality of melanoma; in nonmelanoma skin cancers basal cell carcinoma and squamous cell carcinoma , sun protection does decrease the incidence of new cancers.

At least sun protection factor SPF 30 with UVA and UVB protection used as directed and reapplied every 2 hours and after swimming or sweating but not used to prolong sun exposure.
Doctors do not know whether these measures reduce the chances of people developing or dying of melanoma. However, sun protection does decrease the risk of developing basal cell carcinoma and squamous cell carcinoma , and using tanning beds, particularly by young people, does seem to increase the risk of melanoma.
Doctors treat most skin cancers by removing them surgically. Usually, the scar that is left after surgery depends on the size of the original cancer which if caught early, will be small. Larger or more invasive cancer may require removal of a significant amount of skin, which may have to be replaced with a skin graft or a skin flap.
With a skin graft, a piece of skin is removed from another area of the person's body, typically where the skin is loose.
The piece of skin is sewn onto the area where the cancer was removed. With a skin flap, doctors transfer skin from an adjacent area to replace the area where the cancer was removed. With a flap, but not with a graft, the transferred skin is not cut completely free, so it still has its own blood supply. Also, a flap is usually thicker than a graft. The Skin Cancer Foundation.
