Everybody knows that colonoscopy is the best test to screen for colorectal cancer and that colonoscopies save lives. Everybody may be wrong. Colonoscopy is increasingly viewed as the gold standard for colorectal cancer screening, but its reputation is not based on solid evidence. In reality, it is not yet known for certain whether colonoscopy can help reduce the number of deaths from colorectal cancer. Screening with fecal occult blood testing (FOBT) and flexible sigmoidoscopy are supported by better evidence, but questions remain. It seems our zeal for screening tests has outstripped the evidence.
Statistics show that the life-time risk for an adult American to develop colorectal cancer (CRC) is approximately 6%. Colorectal cancer is the second leading cause of cancer deaths in the United States. In the US there are currently 146,970 new cases and 50,630 deaths each year. Between 1973 and 1995, mortality from CRC declined by 20.5%, and incidence declined by 7.4% in the United States. Read more »

Unless you’ve been living on another planet, you know that in mid-November, the US Preventive Services Task Force released new recommendations on screening mammography, in which they recommended against routine mammogram screening in women under age 50, and recommended that mammograms now be every two years in women ages 50-74.
What you may not have heard is that the Task Force has acknowledged that the mammogram guidelines were poorly worded, and have revised their original statement to clarify their intentions, mostly by removing those two little words “recommends against”. Read more »

Steve Novella whimsically opined on a recent phone call that irrationality must convey a survival advantage for humans. I’m afraid he has a point.
It’s much easier to scare people than to reassure them, and we have a difficult time with objectivity in the face of a good story. In fact, our brains seem to be hard wired for bias – and we’re great at drawing subtle inferences from interactions, and making our observations fit preconceived notions. A few of us try to fight that urge, and we call ourselves scientists. Read more »

Right in the middle of the national firestorm about Mammogram recommendations, the American College of Gynecologists (ACOG) has issued new guidelines for screening of cervical cancer. After 40 years of successfully convincing women to get pap smears annually, the new recommendations say women should not get their first pap test until age 21 and the intervals for testing can then be stretched out.
The new recommendations say that women should start pap screening at age 21 (not teens who are sexually active as previously recommended) and then every two years through age 29. Women age 30 and over with three negative pap smears can stretch it out for three years. Women over age 65 can stop getting pap tests if their previous tests have been negative. Women who have had a hysterectomy for non-cancer reasons never need a pap smear. Read more »
