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
