May 28, 2012 A federal task force's recommendations against routine blood tests for prostate cancer raises big questions about how to interpret medical evidence and what role expert panels should play in how doctors practice. But those questions aren't easy to answer.
May 22, 2012 Over the past decade or so, sigmoidoscopy has been largely abandoned by doctors in the U.S. in favor of colonoscopy to detect and prevent colon cancer. But sigmoidoscopy is easier on patients and is also effective in finding precancerous polyps.
May 21, 2012 The U.S. Preventive Services Task Force says the testing doesn't save enough lives to justify the risk of unnecessary surgery and radiation.

April 10, 2012 Researchers conclude that spiral CT, which makes 3-D pictures of lungs, could reduce lung cancer deaths by 35 percent at a cost of $19,000 to $26,000 per year of life saved. The findings apply to people at high risk for developing lung cancer.
April 9, 2012 Cancer care costs more in the U.S., but people live longer than they do in European countries, according to new research. But the numbers are 10 years old, and it will take more research to know if today's increased spending is worth it.
