Physical activity, obesity, and risk for colon cancer and adenoma in men

Article Abstract:

Men who are physically active may have a lower risk of colon cancer, but men who are tall or obese may have an increased risk. Surveys conducted in 1986 and 1987 of 47,723 male health professionals, including dentists, optometrists, and pharmacists, asked respondents about their physical activity level, body mass index, and waist and hip circumferences. Respondents were followed up from 1986 to 1992, during which time 203 were diagnosed with colon cancer and 586 were diagnosed with adenomas (benign tumors). Moderate levels of physical activity may be associated with a significantly lower risk of colon cancer among middle-aged to elderly men. Higher levels of physical activity may reduce the risk even further. Obesity, especially the presence of abdominal fat, may increase the risk for colon cancer even if a person is physically active. Physical activity may not protect against the development of rectal tumors. Height, with or without obesity, may be associated with an increased risk for colon cancer. Taller persons may have longer colons, with more cells at risk for malignant transformation.

Alcohol consumption, cigarette smoking, and risk of benign prostatic hyperplasia

Article Abstract:

The risk of benign prostatic hyperplasia (BPH) and alcohol consumption and cigarette smoking are discussed based on a study of 29,386 men aged 40-75 in the Health Professionals Follow-up Study. Findings indicate that avoiding smoking may be of benefit relative to BPH, as may moderate alcohol consumption.
