Watching a lot of TV linked to higher colorectal cancer risk
As the nation marks Colorectal Cancer Awareness Month in March, Washington University School of Medicine researchers have just published a new study showing that younger people who spend a lot of time on their couches watching TV may be at increased risk of early-onset colorectal cancers.
While the incidence of colorectal cancer has decreased dramatically among adults over 50 in recent years, largely due to better screening, it is on the rise among younger Americans – and the medical community does not yet understand why. Earlier onset colorectal cancers also tend to be more aggressive and found at later stages than those in older patients, resulting in less favorable outcomes and more loss of life.
The Wash U researchers specifically compared data on average daily TV viewing time with diagnoses of colorectal cancers in under-50 adults, using information from more than 89,000 American women participating in the long-term Nurses’ Health Study II. They found that more than one hour of sedentary TV viewing time every day was associated with a 12 percent increased risk of cancer, compared with those who watched less than an hour. The results were far more dramatic for those who watched more than two hours each day, who had a nearly 70 percent increase in risk.
The relationship between time spent watching TV and early cancer held regardless of individual exercise levels and body mass index [BMI], and was consistently seen among women with no family history of colorectal cancer. The association was also more pronounced for rectal cancer compared to colon cancer.
“This study may help identify those at high risk and who might benefit more from early screening,” said Yin Cao, assistant professor of surgery and a study co-author. “The fact that these results were independent of BMI and physical activity suggests that being sedentary may be an altogether distinct risk factor for young-onset colorectal cancer.”
