The skin is the bodies biggest defence unit. It protects organs, controls tempature and regulates body fluids. The epidimus is divided into two seperate parts, the epidermis, dermis, and subcutis. The epidermis is made up of Keratinocytes. Keratinocytes contain an essential protein called keratin. Keratin helps the skin protect the rest of the body.

Cells called melanocytes are also found in the epidermis. Melanocytes give the pigment to the skin. Melanocytes are what protect the body from the sun. When a tumour becomes maligant in the melanocytes, it is known a Melonama skin cancer.

The middle part is the dermis. The dermis contains blood vessals, sweat glands and hair follicles.
The last layer is known as thesubcutis. The subcutis contains fat cells.

Types of NonMelanoma Skin Cancer

Basal cell carcinoma
Is formed in the epidermis. About 75% of the skin cancers in women and 85% of the skin cancers in men are Basal cell carcinoma. Basal cell carcinoma generally devolp on sun exposed areas. The head and neck are common places to find Basal cell carcinoma. At one time Basal cell carcinoma was found exclusivily in the middle aged or the old. Now however it is found in both the old and the young without discrimination. The increase in the youth catching Basal cell carcinoma is probbally due to greater amount of times spent in the sun without protection. Basal cell carcinoma grows slow. If Basal cell carcinoma is left untreated it can advance into other cells such as the bones and tissue beneath the skin. Once removed Basal cell carcinoma can recour and people who have devolped Basal cell carcinoma have a 42% chance of contracting another skin cancer within five years.

Squamous cell carcinoma
Squamous cell carcinoma accounts for approximity twenty percent of all skin cancers. Squamous cell carcinoma appears on sun exposed areas.Squamous cell carcinoma tend to be less agressive than Basal cell carcinoma. Squamous cell carcinoma tend to invade fat cells beneath the skin.

Kaposi sarcoma
In the nineteen eighties, Kaposi sarcoma was almost excusivily found in older people of medditrian decent.  Kaposi sarcoma tends to be aquired by people who have Human immunodeficiency virus  Because Kaposi Sarcoma is caught by people who have Human immunodeficiency virus it has become more commona and in different age groups and ethnicities.

Merkel cell carcinoma
Merkel cell carcinoma is a rare skin cancer. Merkel cell carcinoma is found in about five hundred
different cases in the united states each year. Merkel cell carcinoma commonly comes back after
treatment and can spread to the lympth nodes.

cutaneous lymphoma
Most cutaneous lymphoma  are on patients aged fifty to sixty years old. A very small percentage(less
than 4%) are aged as young as twenty years old. The diesease tends to begin on the trunk. After months or years, the patches can evolve into plaques that become scaly and indurated. If the diesease is allowed to continue growth than the tumor stage is next. Because of the slow growth of cutaneous lymphomea
choices in treatment may be difficult.
