Chapter 12, Problem 27QP

Studies 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?

In a study, where the causal relationship between alcohol drinking and colon cancer was studied, there were 2000 people who consume alcohol and there were 2000 people who do not consume alcohol. These populations were followed up for 10 years and after the following period there were 280 people who had colon cancer in alcohol drinker group, compared with 100 people having colon cancer in the non-drinker group. What was the relative risk of having colon cancer risk in alcohol drinkers? explain very detail

ames has conducted an occupational cohort study. He has studied coal miners and their rates of cancer, and has compared them to steel workers, and their rates of cancer. There were 50 coal miners and 20 steel workers. 25% of steel workers got cancer and 40% of coal miners got cancer.
