There are several tests that can be performed to diagnose Kaposi sarcoma, including: physical exams, chest x-rays, and biopsies. For physical exams, doctors will examine your body for general signs of health. This includes checking your skin and lymph nodes for any signs of disease, such as lumps. A chest x-ray of the organs and bones of the chest is taken to look for Kaposi's sarcoma in the lungs. A biopsy is the removal of cells or tissue so that they can be viewed under a microscope to check for cancer. An endoscopy or bronchoscopy may be done to check for Kaposi's sarcoma lesions in the gastrointestinal tract or lungs. Some treatments for Kaposi's sarcoma are antiviral therapy against HIV, combination chemotherapy, freezing of the lesions, and radiation therapy. Lesions may recur after treatment. Treating Kaposi's sarcoma will not improve your chances of surviving AIDS. The prognosis depends on the person's immune system and the amount of HIV present in the blood. There are always possible complications including coughing up blood, shortness of breath, swelling in the legs and infections in the lymph may occur. Kaposi's sarcoma can be fatal for a person affected by it
