of body cavities). For this type of tumor, surgical removal is the common treatment choice. However, removal is not guaranteed as the tumor sometimes adheres strongly to surrounding muscles and tissues. Mastocytoma are the second most common skin tumor in cats. They are usually single nodules in the skin, most commonly on the head and neck; in about one quarter of cats, the nodules become ulcerated. Multiple nodules occur in about 20% of cases. Melanomas are not common in cats but when they are, they manifest as basal cell tumors. These tumors are benign in nature, but are firm and raised from the surface of the skin. They are commonly found around the neck, head, ears, and shoulder regions and can be treated through chemotherapy or radiation therapy. Myeloproliferative tumors are types of genetic disorders passed through generations. It can affect the bone marrow, white and red blood cells, and platelets. Similar symptoms occur in blood clotting disorders, they include weakness, labored breathing, pale muscus membranes and a loss of appetite. Treatment options for these tumors include chemotherapy, and bone marrow transplants. Osteosarcoma are tumors that mainly affect the joints, bones and lungs. Osteosarcoma can lead to swelling, loss in dexterity, coughing, and breathing difficulties. Diagnosis is done by radiographs usually followed by a biopsy. Treating osteosarcoma treatment involves aggressive surgical intervention that may lead to amputation of the affected limb. Squamous cell carcinomas affect areas that lack natural pigmentation (oral cavity, tonsils, lips, nose, eyelids, outer earal ear, limbs, toes and nails), or areas that are under constant trauma and irritation. They are diagnosed through biopsy testing. Treatment options include: surgery, cryotherapy, hyperthermia, chemotherapy, and radiation. Diagnosis Diagnosing the type of cancer, by the analysis of the structure of the tumor and cancer cells, helps determine the best treatment. Physical examination is the most common diagnostic method because typically most tumors can be diagnosed using physical examination with visual observation and manual palpation. X-rays are divided by two types: plain film and constrat techniques. They are commonly used to identify tumors of the lung, gastrointestinal tract and bladder. Ultrasonography is used to visualize internal bodily structures, and can diagnose internal tumors. It is also a way to see internal cysts (which may become tumors) and to see the size and structure of the organs. Cytology involves taking cells from the affected area, such as mammary gland secretions, nasal secretions,
