癌症是美国最常见的死亡病因。由于诊治方法的进步,癌症病人的存活率已由本世纪初的1/5提高到现在的1/2。然而,有一部分美国癌症患者的死亡率高而存活率低。长期以来许多人认为种族是造成这种差别的根本原因。本文试图说明社会经济状况的差别是决定癌症发病率、死亡率和存活率的主要因素,并提出了一些降低社会经济地位低下阶层癌症发病率、死亡率,提高存活率的推荐措施。
Cancer is the most common cause of death in the United States. As a result of advances in diagnosis and treatment methods, the survival rate of cancer patients has increased from 1/5 at the beginning of this century to 1/2 now. However, some American cancer patients have high mortality rates and low survival rates. Many people have long believed that race is the root cause of this difference. This article attempts to show that the difference in socio-economic conditions is the main factor that determines the incidence, mortality, and survival rate of cancer, and proposes some recommended measures to reduce the incidence, mortality, and survival rate of low-level socioeconomic status of cancer.
