Mast cells are involved in allergic reactions. Alternatively, because mast cells are sensitive to radiation, radiation treatment may be effective if there is remaining tumor. Thus far, all the tested treatment procedures improved the signs of the disease but did not lengthen an affected dogs life. In dogs, fibrosarcomas are invasive tumors that spread into surrounding tissues; only about 10% of these tumors spread to other parts of the body (metastasize). They seldom spread to other sites but tend to return after surgical removal. The sebaceous glands secrete the oil known as sebum into the hair follicles and onto the skin. They most commonly develop on the head and forelimbs in middle-aged or older dogs. It is uncommon for these tumors to spread to other organs. There are several tumors that arise from the connective tissue that provides a covering for nerves. Use OR to account for alternate terms Fibrous tissue consists of bundles of collagen (protein) fibers that lie between rows of connective tissue cells. Peripheral Odontogenic Fibroma.
