Thun, the lead author of the study and the head of epidemiologic (流 行病学的)research for the American Cancer Society. The study is being【C12】______online in PLoS Medicine.
Dr. Thun【C13】______that although nonsmokers do have some risk, smokers are much【C14】______off: a man who never smoked has a 1.1 in 100 risk of dying【C15】______lung cancer, but it jumps to 1 in 5 if he【C16】______In women, the risk goes from 0.8 in 100 to 1 in 8. The figures【C17】______, depending on how much a person smokes.
The study found that among【C18】______who never smoked, Asians living in Asia (not those in the United States) and African-Americans had higher【C19】______of illness and death from lung cancer than did people of European【C20】______. [br] 【C20】
选项
