Skin cancer, although it seems small, can be quite deadly if it is not caught on time. As for how it develops, the cancer develops when DNA is damaged beyond repair. The cells that are damaged then grow and divide at a rate that is uncontrollable. When this damage occurs in the skin and the cells grow and divide uncontrollably, skin cancer is the result. The damaged cells will continue to multiply and that will cause a tumor.
The cancer usually develops in the epidermis, which is the outermost skin layer. That is why the skin cancer tumor is usually quite visible. This is why skin cancer is usually detectable in the early stages.
