Analytic epidemiology includes two types of studies: observational studies, such as case-control and cohort studies, and experimental studies which include clinical trials or randomized clinical trials.

Then the researchers, led by Dr. Michael J. Thun of Atlanta, where he is director of analytic epidemiology for the cancer society, measured death rates from cancer among the women through 1989.

Cigar smoking "presents risks from cancer of the larynx, mouth and esophagus," said Dr. Michael J. Thun, director of analytic epidemiology for the American Cancer Society in Washington.

Asked to comment on the study, Dr. Eugenia Calle, director of analytic epidemiology at the American Cancer Society, said, "The study is provocative, but it is much too early to say it's definitive."

Use analytic epidemiology (case-control and cohort studies and presentation of data using 2 x 2 tables, odds ratios, relative risks, and tests of significance) for hypothesis generation, risk factor identification, outbreak investigations and intervention design and monitoring.

Suspicions that hair dyes might increase cancer risk have been around since the 1970's, said Dr. Eugenia Calle, the cancer society's director of analytic epidemiology, but studies over the years have found no connection between the dyes and most forms of cancer.

Dr. Michael Thun, the lead author of the study and the director of analytic epidemiology for the American Cancer Society, added a note of caution to the results of the study, saying: "The study does not represent the major hazards of alcohol abuse.

Dr. Thun, director of analytic epidemiology for the American Cancer Society in Atlanta, said that such a decision would have to be based on other reasons, such as the evidence that low doses of aspirin can significantly reduce heart attacks and strokes in people known to face a high risk of developing these diseases.
