The study, published in Cancer Epidemiology, Biomarkers & Prevention, looked at how different types of fear influenced colorectal cancer screening decisions in nearly eight thousand UK adults. Different experiences of fear were found to have different effects on people’s likeliness to get tested…
By clarifying which patients are at highest risk for reduced sperm production as adults, researchers expect the findings to eventually increase use of pre-treatment fertility preservation methods such as sperm banking. The study involved drugs called alkylating agents that are widely used to treat a variety of pediatric cancers. …
“There have been some concerns that one of the reasons why breast cancer may be more common in developed countries compared with developing countries is differences in bra-wearing patterns,” said Lu Chen, MPH, a researcher in the Public Health Sciences Division at Fred Hutchinson Cancer Research Center and a doctoral student in the Department of Epidemiology at the University of Washington School of Public Health. “Given how common bra wearing is, we thought this was an important question to address. …

“Twelve MET-h [metabolic equivalent task-hours] per week corresponds to walking four hours per week or cycling or engaging in other sports two hours per week and it is consistent with the World Cancer Research Fund recommendations of walking at least 30 minutes daily,” said Agnès Fournier, PhD, a researcher in the Centre for Research in Epidemiology and Population Health at the Institut Gustave Roussy in Villejuif, France. “So, our study shows that it is not necessary to engage in vigorous or very frequent activities; even walking 30 minutes per day is beneficial.” Postmenopausal women who in the previous four years had undertaken 12 or more MET-h of physical activity each week had a 10 percent decreased risk of invasive breast cancer compared with women who were less active. Women who undertook this level of physical activity between five and nine years earlier but were less active in the four years prior to the final data collection did not have a decreased risk for invasive breast cancer. “Physical activity is thought to decrease a woman’s risk for breast cancer after menopause,” said Fournier…
These results conflict with a recent study published in BMJ’s Journal of Epidemiology and Community Health suggesting that seven or more daily portions of fruits and vegetables were linked to lowest risk of death. There is growing evidence that increasing fruit and vegetable consumption is related to a lower risk of death from cardiovascular disease and cancer. However, the results are not entirely consistent. …
“We found that the use of low-dose aspirin was associated with cutting the risk of pancreatic cancer in half, with some evidence that the longer low-dose aspirin was used, the lower the risk,” said Harvey A. Risch, MD, PhD, professor of epidemiology in the Department of Chronic Disease Epidemiology at the Yale School of Public Health in New Haven, Connecticut…
