Lung Cancer Screening Using Helical CT vs. Chest X-ray Reduces Deaths among Current and Former Heavy Smokers

Computed tomography (CT) scan of the abdomen; drawing shows the patient on a table that slides through the CT machine, which takes x-ray pictures of the inside of the body.

a study sponsored by the National Cancer Institute (NCI) has determined that low-dose helical computed tomography (CT) scans can reduce lung cancer mortality for current and former heavy smokers. In the nation-wide study, which included over 53,000 participants, researchers found 20 percent fewer lung cancer deaths among those who were screened with low-dose helical CT (also known as spiral CT) compared with those who were screened with chest X-rays. In addition, deaths from all-causes (including lung cancer) were seven percent lower in those who received the low-dose helical CT scans.

The Role of Fecal Occult Blood Testing in Colorectal Cancer Screening

Each year nearly 150,000 people in the U.S. are diagnosed with colorectal cancer and around 50,000 die from the disease. Studies have shown that when performed every one to two years in people ages 50 to 80, fecal occult blood tests (FOBT) can help reduce the number of deaths from colorectal cancer by 15 to [...]
