Skin cancer is an ailment where skin cells are unable to divide and grow normally. Healthy skin cells generally divide in a particular manner and replace dead cells and develop new skin. Unusual cells can grow uncontrollably and create a lump or 'tumor'. When these abnormal cells develop in the skin, the mass is called a skin tumor.
A skin tumor is considered mild if it is confined to a few cell layers and does not transgress surrounding tissues or organs. But if the tumor disseminate to surrounding tissues it is termed as cancerous.
Cancer cells drift out and destroy surrounding healthy cells catapulting growths and forming malignant tumors.
There are various types of skin cancers based on the kind of skin cell from which they arise. Each kind of human skin cancer displays its own unique appearance. Certain skin cancers are ought to grow in particular locations of the body.
Basal cell carcinoma and squamous cell carcinoma are termed as non-melanoma to bring them out from the relatively serious melanoma skin cancers.
Ultraviolet (UV) Radiation emitting from the sun is the major cause of skin cancer. Rays from the sun actually is a kind of radiation. It comprises of visible ray and other light that are not visible by the people. Invisible infrared radiation, for example, gives a hot feeling to the sunlight.

Keeping in view the complexity of treatment, people with malignant melanoma may get advantage from the combined expertise of the dermatologist, a cancer surgeon.
Radiation therapy: The use of high-energy rays to destroy cancer cells, curbing them from growing and multiplying is called radiation therapy. Like surgery, radiation therapy is a local remedy that affects cancer cells only in the applied area.
Chemotherapy is usually administered in frequent cycles. One treatment period is followed by a recuperation period, then again another treatment period, and it goes on. Usually a patient has to undertake chemotherapy as an outpatient in the clinic or hospital. However, depending on the kind of drugs given to the patient and patient's general health, the patient may have to get admitted in the hospital for a brief period of time.
