In England, getting screened and treated for colorectal cancer -- the second leading cause of cancer death in the United Kingdom and worldwide -- is free. So why do only about half of thepopulation go through with it? The answer, suggests a new study in the journal Cancer Epidemiology, Biomarkers and Prevention, is something of a self-fulfilling prophecy:people believe if they're going to get cancer, they'll die from it anyway, so why bother? This attitude, known as cancer fatalism, is known to be a factor in African Americans' lower rates of colorectal cancer screening in the U.S. It may also be a key reason people of lower socioeconomic status in the U.K. fail to follow through on testing, reported University of London Psychologist Anne Miles and colleagues.

Colon cancer is most common in Westernized countries, such as the United States and European nations. That means lifestyle has a lot to do with why the disease develops. A study published Wednesday confirms that adhering to five basic health tenets could dramatically reduce the risk. In a study of more than 55,000 Danish men and women ages 50 to 64, researchers found these five factors cut colorectal cancer risk by 23%: -- Not smoking. -- Drinking no more than seven alcoholic drinks a week for women and 14 drinks for men. -- A waist circumference below 34.6 inches for women and 40 inches for men. -- Consuming a healthful diet (based on four recommendations: adequate daily intake of fruits, vegetables and fiber, and limiting consumption of red and processed meat and total fat.)

Colorectal cancer is the third-leading cause of cancer and death in the United States. So previous research hinting that statins, which an estimated 20 million Americans take to improve their cholesterol levels, might cut the risk of colorectal cancer has generated high interest. However, a study released Monday yielded disappointing news. Researchers studying a large group of postmenopausal women found that those who took statins did not have a reduced risk of colorectal cancer.

Of the 7 million Americans a year who undergo a colonoscopy, it's safe to say that none looks forward to it eagerly. Who would? Doctors insert a 5-foot flexible tube through the anus to inspect the rectum and the entire colon, or large bowel, looking for signs of cancer. Yet the vast majority of patients, doctors say, find the colonoscopy procedure much less painful and stressful than they expected.

Thalidomide, a drug notorious for causing birth defects but now being tested against a range of diseases, will also be tested against colon cancer, says Celgene Corp., which owns the rights to it. Celgene said the National Cancer Institute would sponsor the tests. Thalidomide caused severe birth defects when used by pregnant women as a tranquilizer in the 1950s and 1960s. Restrictions on testing and using it are designed to ensure that women who might become pregnant are not exposed.

People with Down syndrome suffer cancer less than most other people, and a study in mice published Thursday in the journal Nature gives one possible explanation -- they produce higher levels of a protein that may keep tumors from growing. Researchers at Johns Hopkins University found that a gene called Ets2 protected mice from colon cancer. The researchers used mice bred to develop colon cancer at extreme rates, and genetically engineered them to produce extra amounts of Ets2. The more Ets2 the mice had, the less likely they were to develop colon cancer.
