Geographical aspects of cancer in Tanzania.
Cancer is an important cause of morbidity and mortality in Tanzania. According to the Tanzanian Cancer Registry, which records all histologically confirmed malignant tumors, the number of reported cancer cases has increased significantly over the past three decades. The most commonly diagnosed tumors are cervix cancer, skin cancer, primary liver cancer, Kaposi's sarcoma, and Burkitt's lymphoma. Geographical and tribal variations exist in disease frequency. Environmental factors appear to have a major role in the distribution. Through elimination of these factors, cancer in Tanzania could be reduced if not totally prevented.
