Why do you think tobacco use increasesthe risk of other types of cancer besideslung cancer?
A survey of Canadian males was performed in during the 1980s. 52% of adult males smoked. The lifetime probability of getting lung cancer in male smokers was 17.2% compared to 1.3% in non-smoking males.
c)Use your probability tree to calculate the following:
An elderly Canadian male developed cancer
What is the probability that he smoked?
Pr[smoke | cancer] = ?
pls help me with the following and explain. thank you
If the risk of a particular type of cancer is expressed as 32 excess fatalities per 10,000 per Sv, how many excess fatalities would we expect in a poppulation of 3,000 exposed to 400mSv?

- Smoking cigarettes has been shown to be associated with the development of lung cancer. However, a direct correlation between how many cigarettes one smokes and the onset of lung cancer does not exist. A heavy smoker may not develop lung cancer, whereas a light smoker may develop the disease. Explain why this may be.arrow_forwardSometimes slides of a coal miner's lung and of lung cancer are available. Either use slides or the internet to examine the histology of lung cancer and a coal-miners / or smoker’s lung.arrow_forwardresearchers have noticed that some men who were sterile because their sperm cells were unable to move also had a chronic infection of the respiratory tract. what might be the connection between these two symptoms?arrow_forward
- 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. (e) Interpret your finding in the question What was the relative risk of having colon cancer risk in alcohol drinkers (what does the relative risk you found out)? explain in great detailarrow_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_forwardA survey of Canadian adult males was performed during the 1980s. 52% of the respondents smoked.
