Question

Direction：Read the following passage．Answer the questions according to the information given by the passage．

　　Behavioral risk factors have a great effect on cancer risk in the elderly population of the US, according to a research．About 80 percent of all cancers are diagnosed(诊断)in the elderly, and more than 80 percent of known risk factors are possibly preventable, US researchers say．

　　Igor Akushevich of Duke University in Durham, N．C．, said the main purpose of the study was to discover a way to find out the contributions of measurable risk factors to cancer risk among the elderly．More analysis is needed before the finding can actually be used．“So far, we have not come to the stage where we are able to make specific recommendations regarding risk factors,” Akushevich said in a statement．But according to the study, cigarette smoking does increase the risk of lung cancer．

　　The researchers said they were surprised at some of the findings．Cancer risk is not connected with alcohol drinking, as reported in other studies．A possible explanation may be that those aged 65 or older tend to drink moderately(适度地)．

　　“Other interesting findings are an increased risk of breast cancer for those women who are afraid to go to the doctor to have examinations and a decreased risk of breast and lung cancers for those who never lose their temper,” Akushevich said．

　　Light and moderate physical activities decrease the risk of cancer, but too much exercise may augment the risk, the study said．

　　The findings were presented at the American Association for Cancer Research's International Conference on Frontiers in Cancer Prevention Research．
