- If your father were diagnosed with an inherited disease that develops around the age of 50, would you want to be tested to find out whether you would develop this disease? If so, when would you want to be tested? As a teenager or sometime in your 40s? If not, would you have children?arrow_forwardLook at the question here, ____ Suppose a study looking at the association between smoking and bladder cancer found an odds ratio = 2.4. What would be the best way to interpret this? (Select one answer.) Smokers are 140% times as likely to develop bladder cancer compared to non-smokers. People with bladder cancer are about 40% more likely to be smokers compared to people who don't have bladder cancer. Smokers have a 2.4 % more risk of bladder cancer compared to nonsmokers. Smokers have 2.4 times the risk of developing bladder cancer compared to non-smokers..?arrow_forwardWould you consider the “smoking-lung cancer relationship” as an example of the biological plausibility concept?

- Is heredity the only factor that determines the people we will become? Why or why not?arrow_forwardStudies have shown that there are significant differences in cancer rates among different ethnic groups. For example, the Japanese have very high rates of colon cancer but very low rates of breast cancer. It has also been demonstrated that when members of low-risk ethnic groups move to high-risk areas, their cancer risks rise to those of the high-risk area. For example, Japanese who live in the United States, where the risk of breast cancer is high, have higher rates of breast cancer than do Japanese who live in Japan. What are some of the possible explanations for this phenomenon? What factors may explain why the Japanese have higher rates of colon cancer than do other ethnic groups?arrow_forwardResearchers are very interested in studying identical twins separated at birth and raised apart. So far, data suggests that such twins are more alike than researchers predicted; they frequently have similar personalities, mannerisms, habits, and interests. What general questions do you think researchers hope to answer by studying such twins? Why do identical twins make good subjects for this research? What abuses might occur if the studies are not evaluated critically and if the results are carelessly cited to support a social agenda?arrow_forward
- Two cities each had a population of 1,000,000 in 2010, with the same number of lung cancer-related deaths occurring in the year. Although the prevalence of smoking was 40% for each city, the number of all-cause deaths in Jones Country was a third of that for Bryanville. If the number of all-cause deaths in Jones Country was 50 with 8% of them associated with lung cancer. What is the proportionate mortality ratio for lung cancer deaths for Jones Country (compared) to Bryanville?
