Preview- Evidently, three forms of skin cancer are basal cell carcinoma (i.e., basal cell epithelioma) (basal cell carcinoma epithelioma), squamous (i.e., scaly) cell carcinoma (which is the first stage actinic keratosis (i.e., senile keratoderma, or senile keratoma)), and melanoma (i.e., malignant melanoma (i.e., melanoma)) (the most dangerous. Skin cancer, cancer that forms in the tissues of the skin. There are several types of skin cancer. Skin cancer that forms in melanocytes (skin cells that make pigment) is called melanoma. Skin cancer that forms in the lower part of the epidermis (the outer layer of the skin) is called basal cell carcinoma. Skin cancer that forms in squamous cells (flat cells that form the surface (i.e., face, or facies) of the skin) is called squamous cell carcinoma. Skin cancer that forms in neuroendocrine cells (cells that release hormones in response to signals from the nervous system) is called neuroendocrine carcinoma of the skin. Most skin cancers form in older people on parts of the body exposed to the sun or in people who have weakened immune systems. Basal cell carcinoma, cancer that begins in the lower part of the epidermis (the outer layer of the skin). It may appear as a small white (i.e., albicans) or flesh (i.e., muscular tissue)-colored bump that grows slowly and may bleed. Basal cell carcinomas are usually found on areas of the body exposed to the sun. Basal cell carcinomas rarely metastasize (spread) to other parts of the body. They are the most common form of skin cancer. Also called basal cell cancer. Stage is the extent of a cancer in the body. Staging is usually based on the size of the tumor (i.e., neoplasm), whether lymph nodes contain cancer, and whether the cancer has spread from the original site to other parts of the body. Melanoma is a form of cancer that begins in melanocytes (cells that make the pigment melanin (i.e., melanotic pigment)). It may begin in a mole (i.e., nevus, or nevus pigmentosus) (skin melanoma), but can also begin in other pigmented tissues, such as in the eye (i.e., oculus) or in the intestines. Squamous cell, flat cell that looks like a fish scale (i.e., squama) under a microscope. These cells cover inside and outside surfaces of the body. They are found in the tissues that form the surface of the skin, the lining of the hollow organs of the body (such as the bladder, kidney (i.e., ren, or nephros), and uterus (i.e., metra, or womb)), and the passages of the respiratory and digestive (i.e., digestant) tracts. Squamous cell carcinoma, cancer that begins in squamous cells, which are thin, flat cells that look like fish scales. Squamous cells are found in the tissue that forms the surface of the skin, the lining of the hollow organs of the body, and the passages of the respiratory and digestive tracts. Also called epidermoid carcinoma (i.e., epidermoid cancer). Actinic keratosis is a thick, scaly (i.e., squamous) patch of skin that may become cancer. It usually forms on areas exposed to the sun, such as the face, scalp, back of the hands, or chest (i.e., pectus). It is most common in people with fair skin. Also called senile keratosis (i.e., actinic keratosis) and solar keratosis (i.e., actinic keratosis).

Malignant, cancerous. Malignant cells can invade and destroy nearby tissue and spread to other parts of the body.
- It`s apparent that, in this form of skin cancer, basal cells in the epidermis are altered so they no longer produce keratin (i.e., ceratin, or cytokeratin). Keratin is a type of protein found on epithelial cells, which line the inside and outside surfaces of the body. Keratins help form the tissues of the hair (i.e., pilus), nails, and the outer layer of the skin. They are also found on cells in the lining of organs, glands, and other parts of the body. Certain keratins may be found in higher than normal amounts in patients with different types of epithelial cell cancers, including lung (i.e., pulmo), breast (i.e., mamma, or teat), colorectal, bladder, and head (i.e., caput) and neck (i.e., cervix, or collum) cancers. Measuring the amount of specific keratins in the blood may help to plan cancer treatment or find out how well treatment is working or if cancer has come back. A keratin is a type of tumor marker. Also called cytokeratin (i.e., keratin). Epidermis is the outer layer of the two main layers of the skin.
