Taking a low-dose aspirin prior to having a fecal occult blood test appears to increase the ability of the test to detect colorectal cancer, according to a new study. The fecal occult blood test, which looks for blood in the stool, is a common test used to detect colon cancer because advanced colorectal tumors often bleed. Moreover, use of low-dose aspirin is a common practice in people ages 55 and older because studies show the therapy can reduce the risk of cardiovascular disease and cancer.

The doctor will see you now – and she has four legs and a tail. That’s right. Japanese researchers have trained an 8-year-old Labrador retriever to diagnose colorectal cancer by smelling a patient’s breath and/or poop. The Lab (who previously worked as a water rescue dog) had an overall accuracy of 95% when using the breath test and 98% for the stool test, according to a study published Monday in the journal Gut. To train the dog, researchers first let her sniff a breath sample from a patient with colorectal cancer.

Colorectal cancer kills more than 55,000 Americans each year. It's a cancer of the colon and/or rectum, which are both part of the large intestine. Here are some more facts--and suggestions to lower your risk: * Anyone can get colorectal cancer, but it usually strikes people older than 50. * Colorectal cancer is the No. 2 cause of death from cancer. (Lung cancer is No. 1.) * Get screened regularly after age 50. These tests can find noncancerous tumors--polyps--that sometimes turn into cancer.

Increased screening during the last decade for colorectal cancer, the nation's second-leading cause of cancer deaths, has put a sharp dent in the prevalence of the disease and in the number of deaths resulting from it, the Centers for Disease Control and Prevention said Tuesday. As screening for the disease among those ages 50 to 75 increased from half to two-thirds of that population, the prevalence rate fell from 52.3 cases per 100,000 in 2003 to 45.4 per 100,000 in 2007. The death rate fell from 19 per 100,000 to 16.7 per 100,000 during the same period, the agency reported in its Morbidity and Mortality Weekly Report . Those declines represent 66,000 fewer cancers during the period and 32,000 fewer deaths, the agency found.

Pour yourself a nice big bowl of whole-grain cereal. A study finds that diets high in fiber, particularly from cereal and whole grains, may reduce the risk of colon cancer. The study, released online today in the British Medical Journal , is a meta-analysis of 25 studies that examined the relationship between dietary fiber and colorectal cancer, the third most common type of cancer diagnosed among men and women in the U.S., according to the American Cancer Society. Previous studies have shown that dietary fiber may decrease colorectal cancer risk, but the authors of this study said it's not apparent whether certain types of fiber are key. After analyzing these papers they found that for every 10 grams of dietary fiber and cereal fiber there was a 10% reduced risk of colorectal cancer.

Contrary to popular belief among physicians and patients, the family of hypertension drugs known as beta-blockers does not prevent development of colon and rectal cancer, German researchers reported Monday. In fact, long-term use of the drugs might even be associated with an increased risk of developing an advanced form of the disease, they said. Beta-blockers are a family of drugs that reduce blood pressure and improve heart function by reducing the body's response to stress hormones such as epinephrine and norepinephrine.
