Web Tool Predicts Colon Cancer Risk

A new online tool can help calculate your risk for colorectal cancer if youíre age 50 or older. A better understanding of your risk will help you and your doctor make more informed choices about which screening tests you should take to detect signs of cancer before symptoms appear.

It takes only 5-8 minutes to answer about 15 questions at the online toolís web site. It will then calculate your risk for colorectal cancer.

The initial version of the risk assessment tool is only designed to assess cancer risk for non-Hispanic whites age 50 or older. But NIH scientists are now working to expand the tool to include additional ages and racial/ethnic groups.

Researchers stress that itís important to talk with your primary health care provider about the results.

The new tool is now available online at www.cancer.gov/colorectalcancerrisk/about-tool.aspx

Colorectal Cancer Screening Tests

  • Fecal occult blood test. Analyzes your stool samples for tiny amounts of blood.
  • Digital rectal exam. A doctor uses a gloved finger to feel for abnormal areas in your rectum.
  • Sigmoidoscopy. A lighted tube looks into the rectum and the lower part of the colon.
  • Colonoscopy. A long, flexible lighted tube looks inside the rectum and entire colon.
  • Double-contrast barium enema. X-ray pictures look at your colon and rectum.

  Therapy Curbs Parkinsonís Symptoms

A new study shows that a treatment called deep brain stimulation can improve quality of life for patients with Parkinsonís disease and give them more daily hours without bothersome movement symptoms. However, brain stimulation also carries a greater risk of serious side effects.

Deep brain stimulation has been used for over a decade to treat patients whose Parkinsonís symptoms are no longer effectively controlled with medication. The procedure involves surgically implanting tiny electrodes into brain regions that control movement. When the electrodes are stimulated, they inhibit the malfunctioning brain signals that cause the movement problems of Parkinsonís.

The new study looked at 255 patients with advanced Parkinsonís disease. They were randomly assigned to receive either deep brain stimulation or standard therapy, including medication.

By 6 months after surgery, movement control improved in 71% of patients who received brain stimulation, compared to 32% in the standard therapy group. On the down side, serious problems like infection from surgery were seen in 40% of patients who received brain stimulation but just 11% in the other group. Most of the side effects, however, improved within a few months.
