ORVALLIS - Oregon State University's 57th annual Biology Colloquium Thursday, April 18, will bring prominent scientists to the campus to discuss what is known about diet and cancer prevention.

"Statistics now suggest that one in four Americans will have cancer and that there's a strong link between cancer and what we choose to eat," said George Bailey, an OSU food scientist who is coordinating the colloquium.

"We usually think of that food link as negative," said Bailey. "But the goal of this year's colloquium is to bring students, professors, the medical profession and anyone else who's interested up to date on what we're finding about things you can eat that may reduce cancer risks."

The colloquium, "Diet and Cancer: From Basic Science to Clinical Trials," will be held in OSU's LaSells Stewart Center. Registration will begin at 8:15 a.m. The program starts at 9 a.m. with a presentation by Dr. Lee W. Wattenberg of the University of Minnesota titled "Chemoprevention of Cancer: An Overview." The medical pathologist is often credited with pioneering the field of cancer chemoprevention.

Other presentations:

• 10 a.m. - "Monoterpenes in the Prevention and Treatment of Cancer," by Michael Gould. The University of Wisconsin cancer researcher pioneered research with citrus-based compounds called "monoterpenoids" thought to play a role in the prevention of breast cancer.
• 11 a.m. - "Green Tea and Garlic Components in the Prevention of Cancer," by Chung S. Yang. The Rutgers University toxicologist is known for his work on preventing cancer of the esophagus in China.
• 1:30 p.m. - "Indoles, Chlorophylls and DHEA - Anti-carcinogens or Tumor Promoters?," by George Bailey. The OSU food scientist is known for his innovative use of rainbow trout in the study of several types of food-related cancer.
• 2:30 p.m. - "Nutritional Prevention of Cancer With Selenium: Results of a Randomized Trial," by Larry Clark. The epidemiologist with the Nutritional Prevention of Cancer Project at the Arizona Cancer Center, University of Arizona, is studying selenium's influence on colon cancer.
• 3:30 p.m. - "Cancer Prevention Trials Sponsored by the National Cancer Institute," by Peter Greenwald. Greenwald is director of the National Cancer Institute's Division of Cancer Prevention and Control.

At 4:30 p.m. all the presenters will answer final questions from one another and from members of the audience.

The colloquium is open to the public. There will be no admission charge. For more information contact Sandy Segna in OSU's Department of Food Science and Technology at 541-737-6530.
