A study by University of Kentucky researchers showed that in Appalachia, colorectal cancer screening rates were higher in the population with multiple morbidities or diseases compared to those who had no morbidities at all. Published in the Southern Medical Journa l, the study used data based on a survey of 1, 153 Appalachian men and women aged 50-76. Respondents were given four sets of questions designed to gather information on demographics; the presence of co-mordibities such as heart disease, diabetes, stroke, and various types of cancer; adherence to colorectal cancer screening guidelines; and barriers to and facilitators of colorectal cancer screening behavior. Researchers found a dose-response relationship between the number of morbidities and the prevalence of colon cancer screening in the Appalachian population.
The American College of Gastroenterology (ACG) and the Campaign to End Obesity (CEO) are joining forces to highlight the potentially deadly link between higher Body Mass Index (BMI) and colorectal cancer. In light of the increasing prevalence of obesity in the United States and the strength of the scientific evidence linking obesity to increased colorectal cancer risk, the two organizations are combining efforts during March Colorectal Cancer Awareness Month. Their goal is to educate the public about obesity as a major risk factor for the second leading cancer killer in the United States and about the importance of colorectal cancer screening in patients with high Body Mass Index. "Dietary and other modifiable risk factors may account for as many as 90 percent of colorectal cancers, and recent studies suggest that about one-quarter of colorectal cancer cases could be avoided by following a healthy lifestyle, " explained ACG President Lawrence R.
Worries About Quality Of Colon Cancer Screening Follow Pressures To Increase Volume Of Colonoscopies
Researchers at Mount Sinai School of Medicine have found that 92 percent of more than 1, 000 gastroenterologists responding to a survey believed that pressures to increase the volume of colonoscopies adversely impacted how they performed their procedures, which could potentially affect the quality of colon cancer screening. The findings, based on responses from members of the American Society for Gastrointestinal Endoscopy (ASGE), are published in the March 2012 issue of Gastrointestinal Endoscopy. "The number of colonoscopies has risen dramatically over the past fifteen years, but it is imperative that an increase in volume not occur at the expense of quality and safety, " said Lawrence B. Cohen, MD, lead study author and an Associate Clinical Professor of Gastroenterology at Mount Sinai.
Whilst colorectal cancer cases are generally on the decline since the beginning of the millennium, there seems to be an alarming rise in those under 50 hit by the disease. Since 1992, the number of people diagnosed with colorectal cancer has risen by two percent per year. One example, given by the Thomas Jefferson University Hospital in Philadelphia, who have published an article as part of Cancer Awareness month starting 19th March, cites the shocking case of Jessica Nixon from Conshohocken, PA. who was diagnosed with rectal cancer at the age of only 25. Severe stomach cramps and constipation for six months finally prompted her doctor to order a colonoscopy, which revealed stage three colon cancer. She braved six weeks of chemo and radiation six years ago, but the cancer spread to her lungs and liver and she's had to suffer further surgery and regular bouts of chemo to keep the disease from killing her.
Epidemiologists have long warned that, in addition to causing obesity, eating too much fat and sugar puts a person at greater risk for colon cancer. Now, researchers at Temple University have established a link that may explain why. The findings, "Epigenetic Differences in Normal Colon Mucosa of Cancer Patients Suggest Altered Dietary Metabolic Pathways, " were published in the March issue of the American Association for Cancer Research's journal, Cancer Prevention Research. "There have always been questions about why things like diet and obesity are independent risk factors for colon cancer, " said Carmen Sapienza, professor of pathology in Temple's Fels Institute for Cancer Research and Molecular Biology, the study's lead author. "This study suggests how and why high fat diets are linked to colon cancer.
