Skin Cancer

Types of cancer in tissues of the skin. There are several types of skin cancer. Skin cancer that forms in the melanocytes (skin cells, pigments) is called melanoma. Skin cancer that forms in the basal cells (small round cells, based on the outer layer of skin) Basal Cell Carcinoma is called. Skin cancer, forms in cells in the epithelium cells (cells, the platform on the surface of the skin) is considered as Squamous Cell Carcinoma. There are three main types of skin cancers - basal cell carcinoma, carcinoma cells in the epithelium and melanoma. Basal cell carcinoma and most characteristic of cancer cells are high and growth slow process, especially so soon. Melanoma is the most serious form of skin cancer. It affects deeper layers of skin and has the greatest potential to spread to other body tissues. Squamous Cell Carcinoma, may also be circulated internally.


Causes
Ultravioletten (UV) rays of the sun is the leading cause of skin cancer. The energy from the sun is in fact a form of radiation. It is composed of visible light and other radiation, that people can not see. Invisible infrared radiation, for example, felt the warm sunlight. UV is also invisible, and causes sunburn and sun tg. Skin cancer is mainly caused by excessive ultraviolet (UV) rays from the sun (the solar UV radiation) and other sources such as sun or UV lamps.

Heritability - people with a family history of skin cancer are generally at a higher risk for developing the disease. People with fair skin, and a northern European heritage, seem most vulnerable.

They live closest to the equator at a higher altitude, or anywhere, you intense throughout the year the sun.

Basalzell characteristic of cells and skin cancer develops very slowly. And you are the elderly, the more you have more time to develop damage from the sun on your skin. Then you're old, you'll melanoma skin cancer. But skin cancer can develop in young people.

If you had radiotherapy, the treatment will be an increased risk of damage from the sun. They should use and high-factor sun cream. If you have been exposed to radiation through your work, you also have a slight increased risk of melanoma is not skin cancer.:


Treatment
Radiation-Radiation can be used for the treatment of Basalzell and characteristic of tumor cells. Radiation can also be used to treat cancer, lymph nodes. In advanced cancers, which are located in another part of the body, radiation can be used to relieve symptoms. It is also used to treat cancer, coming back (again) after their first treatment with surgery.
Chemotherapy. In chemotherapy, drugs are used to kill cancer cells. For types of cancer is confined to the upper layer of skin creams or lotions anti-cancer agents can be directly on the skin. News of drugs can cause severe inflammation and leave scars. Other types of chemotherapy can be used to treat skin cancers, which focus on other parts of the body.
Radiation therapy is the treatment by radiation at high shrink or kill cancer cells. The radiation may be outside the body or radioactive materials directly into the tumor
The surgery is the first step in the treatment of almost all types of skin cancer. Konventionelle operation (distance the whole field of cancer tissue at a time) is not often used for the basic characteristic of cells and skin cancer. Many basic characteristic cell skin cancer can be removed from the skin quickly and easily.
