(HealthDay News) -- Men who pack on excess pounds as young adults are at heightened risk of developing prostate cancer, although the risk varies by ethnic group, researchers from the University of Hawaii report.
Obesity is a risk factor for many common cancers, including colorectal cancer and breast cancer in postmenopausal women. However, whether obesity plays a role in prostate cancer risk has been unclear, researchers say.
The new study finds that "body mass in both younger and older adulthood, and weight gain between these periods of life, may influence prostate cancer risk," said study author Brenda Y. Hernandez, an assistant professor at the Cancer Research Center of Hawaii.
The report is published in the September online issue of Cancer Epidemiology, Biomarkers & Prevention.
For the study, Hernandez's team looked at the relationship between weight and prostate cancer in a multiethnic population including blacks, Japanese, Hispanics, Native Hawaiians and whites, all of whom who participated in a long-term study called the Multiethnic Cohort. Read more...

Diabetes triples the risk of liver cancer
NEW YORK (Reuters Health) - It appears that diabetes is a strong risk factor for liver cancer, raising the risk two- to three-fold, investigators report.
The study, using data from the Surveillance, Epidemiology, and End-Results (SEER)-Medicare database, is the first population-based study in the US that takes other major risk factors for liver cancer into consideration, according to Dr. Hashem El-Serag, at Baylor College of Medicine in Houston, and colleagues.
Their analysis included 2161 patients aged 65 and older with confirmed liver cancer between 1994 and 1999. A comparison "control" group included 6183 randomly selected individuals, according to the team's article in the medical journal Gut.
The researchers found that 43 percent of liver cancer patients but only 19 percent of control subjects had diabetes diagnosed during the three years preceding the diagnosis of liver cancer -- to exclude the possibility that liver cancer was the cause of the diabetes. Read more...

Good Sleepers More Likely to Eat Right
(HealthDay News) -- Getting enough sleep can help you make healthier food choices, researchers say.
The new study included 542 male motor freight workers, who often work long hours and have irregular shifts. The average age of the participants was 49, and 83 percent were white.
The researchers from the sleep medicine division at Harvard Medical School found that adequate sleep was a strong predictor of healthy food choices, while work experiences were not significant predictors. The findings suggest that adequate sleep mediates the effects of the workplace on healthy food choices. Read more...
