Epidemiology - Article Example Various studies have been performed in order to determine the risk involved in the sector of occupational cancer in falling ill with cancer for those working in this sector. The purpose of the study was to determine the risk of lung cancer as a result of occupational exposure to wood dust. For this research, there were two population-based case-control studies in Montreal, Canada. There was different study populations used in this research. The first study was conducted from the year 1979 to the year 1986. It included men of the age of 35-70 years. These men were diagnosed with cancer at any of the 19 sites. The second study was conducted between the years 1996 and 2001. This population study included both men and women who were aged between 35-75 years.

In both of these studies, the patients included all had incident histological confirmed cancers identified across all major Montreal area hospitals and restricted to Canadian citizens. Both of the studies also included a series of population controls. These population controls were randomly selected from electoral lists. The first study was to explore the possible associations between hundreds of occupational substances and multiple cancer sites that included lung cancer.

A similar study was then later performed in the same region in the late 1990s. This was the second study and it focused more on lung cancer. Both of these studies examined the risk of lung cancer associated with occupational exposure to wood dust while controlling for the major confounders that include smoking and other occupational exposures. The exposure in the study was to the wood dust in occupations such as construction and timber making industries. It was to analyze the first and second study in
