Cancer epidemiological studies

Besides age, the development of colorectal cancer appears to be caused by variety of dietary or environmental factors, comor-bid disease states, and genetic susceptibility to the disease. Table 88-1 lists well-known risk factors for developing colon cancer. Epidemiologic studies of worldwide incidence of colorectal... 

Hawaiian name limu mane ono o) (4b,47). In their diet alone the Hawaiians may be getting all of the necessary agents for the initiation and promotion of gastrointestinal cancer. Epidemiological studies, however, are needed to evaluate the actual role of seaweed diet in the incidence of stomach cancer in Hawaii ( ). 

Cancer. Epidemiology studies discussed in Section 2.2.1.8 clearly indicate an increased respiratory cancer risk in workers engaged in chromate production and chromate pigment production and use.

The purpose of epidemiology is to study the distribution and determinants of disease in a population. Ethical considerations dictate that cancer epidemiology studies are usually observational as opposed to experimental studies.

The criteria for listing an agent in the RoC are (1) as known to be human carcinogens on the basis of sufficient evidence from studies in humans and (2) as reasonably anticipated to be human carcinogen on the basis of limited evidence of carcinogenicity in humans. Such evidence may include traditional cancer epidemiology studies, data from clinical studies, and/or data derived from the study of tissues or cells from humans exposed to the substance in question. 

Chronic-Duration Exposure and Cancer. Epidemiological studies in humans following chronic exposure to MBOCA are very limited. No information is available regarding toxic effects in humans following chronic exposure to MBOCA. 

Other studies have demonstrated a lower risk for specific cancers, such as stomach," mouth/throat and npper digestive tract," endometrial, and epithelial ovarian cancer. Epidemiological studies have reported that higher serum insulin levels are associated with increased risk of colon, breast, and possibly other cancers. Reduction of these insulin levels by whole grains may be an indirect way in which the reduction in cancer risk occurs.
