Study Shows Aspirin Reduces Colorectal Cancer in Those at High Risk
Findings from the first large clinical trial of its kind indicate that taking high doses of aspirin daily for at least 2 years substantially reduces the risk of colorectal cancer among people at increased risk of the disease.
Conducted in the United Kingdom, the trial, dubbed CAPP2, showed a nearly 60 percent decrease in colorectal cancer incidence among men and women with hereditary nonpolyposis colon cancer (HNPCC), also known as Lynch syndrome, who took 600 mg of aspirin daily compared to a placebo. HNPCC is an inherited condition in which mutations in certain genes substantially increase the risk of colorectal cancer as well as several other cancers. People with hereditary mutations in these genes, which are involved in a type of DNA repair process called mismatch repair, typically begin developing cancer in their 40s; approximately 15 percent of all colorectal cancers are attributed to defects in mismatch repair genes.

(Reuters) - Many women who have survived breast cancer often say it was a mammogram that "saved their life," a powerful testimonial that can encourage other women to get regular breast cancer screening tests.

(Reuters) - A genetically engineered smallpox vaccine reduced the risk of death for patients with advanced liver cancer by nearly 60 percent in a mid-stage study, prompting the launch of a later-stage trial.
Scientists at institutions including the University of California, San Diego, and privately held biotech company Jennerex Inc presented Phase 2 trial data on Saturday showing that patients given high doses of the altered vaccine, known as JX-594, lived for a median of 13.8 months compared with 6.7 months for patients treated with one-tenth of that dose.

Regularly drinking, even in moderation, raises the long-term risk of many kinds of cancer, according to a new study.
A burgeoning body of research links alcohol to cancers of the breast, liver, colon, pancreas, mouth, throat, larynx and esophagus. A large new study last week added lung cancer to the list—even for people who have never smoked cigarettes.

Look for a PBS NewsHour story on X-ray body scanners, reported in conjunction with ProPublica, to air later this month.
On Sept. 23, 1998, a panel of radiation safety experts gathered at a Hilton hotel in Maryland to evaluate a new device that could detect hidden weapons and contraband. The machine, known as the Secure 1000, beamed X-rays at people to see underneath their clothing.
