- cancer epidermis
Epidermis is the outer layer of the two main layers of the skin. Cancer is a term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord. Also called malignancy.
Preview- It would appear apparant that, most skin cancers belong to a group called keratinocyte carcinomas or keratinocyte cancers because their cells look a lot like keratinocytes (the most common cell type in normal skin). Carcinoma is a medical word for a cancer that starts in a lining layer of cells (like the skin or the lining cells of the digestive system). Digestive system is the organs that take in food and turn it into products that the body can use to stay healthy. Waste products the body cannot use leave the body through bowel movements. The digestive system includes the salivary glands, mouth, esophagus, stomach, liver, pancreas, gallbladder, small and large intestines, and rectum. Cell type, describes the kinds of cells found in normal or cancer tissue. The cell type is usually identified by looking under a microscope. Some examples of cell types are lymphocytes, melanocytes, and squamous cells. In cancer, it is important to know the cell type in order to diagnose the cancer, plan treatment, and determine prognosis.
- It`s that, squamous cell carcinoma in situ is also called Bowen disease. In situ means that the cancer is only in the epidermis where it began. This is the earliest form of squamous cell skin cancer. In situ is in its original place. For example, in carcinoma in situ, abnormal cells are found only in the place where they first formed. They have not spread. Bowen disease is a skin disease marked by scaly or thickened patches on the skin and often caused by prolonged exposure to arsenic. The patches often occur on sun-exposed areas of the skin and in older white men. These patches may become malignant (cancer). Also called precancerous dermatitis and precancerous dermatosis. 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. Squamous cell, flat cell that looks like a fish scale 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, and uterus), and the passages of the respiratory and digestive tracts. Carcinoma in situ is a group of abnormal cells that remain in the place where they first formed. They have not spread. These abnormal cells may become cancer and spread into nearby normal tissue. Also called stage 0 disease.
- One can deduce that, this is not only the most common type of skin cancer, but the most common type of cancer in humans. Basal cell cancer begins in the lowest layer of the epidermis, the basal cell layer. It usually begins on skin exposed to the sun, such as the head and neck. Basal cell cancer, cancer that begins in the lower part of the epidermis (the outer layer of the skin). It may appear as a small white or flesh-colored bump that grows slowly and may bleed. Basal cell cancers are usually found on areas of the body exposed to the sun. Basal cell cancers rarely metastasize (spread) to other parts of the body. They are the most common form of skin cancer. Also called basal cell carcinoma. Basal cell is a small, round cell found in the lower part (or base) of the epidermis, the outer layer of the skin.
