Why It’s So Tempting To Over-screen: A Personal Perspective

Health screening is part of good preventive care, though over-screening can lead to increased costs, and potential patient harm. Healthcare professional societies have recently developed excellent public service announcements describing the dangers of over-testing, and new research suggests that though additional medical interventions are associated with increased patient satisfaction, they also lead (ironically) to higher mortality rates.

And so, in a system attempting to shift to a “less is more” model of healthcare, why is resistance so strong? When the USPSTF recommended against the need for annual, screening mammograms in healthy women (without a family history of breast cancer) between the ages of 40-49, the outcry was deafening. Every professional society and patient advocacy group rallied against the recommendation, and generally not much has changed in the breast cancer screening world. I myself tried to follow the USPSTF guidelines – and opted out of a screening mammogram for two full years past 40. And then I met a charming radiologist at a women’s medical conference who nearly burst into tears when I told her that I hadn’t had a mammogram. Her lobbying for me to “just make sure I was ok” was so passionate that I simply could no longer resist the urge to get screened.

I knew going into the test that there was a reasonably high chance of a false positive result which could cause me unnecessary anxiety. That being said, I was still emotionally unprepared for the radiologists’ announcement that the mammogram was “abnormal” and that a follow up ultrasound needed to be scheduled. I must admit that I did squirm until I had more information. In the end, the “abnormality” proved to be simple “dense breast tissue” and I was pleased to have at least dodged an unnecessary biopsy or lumpectomy. Did my screening do me any good? No, and some psychological harm. A net/net negative but without long term sequelae.

My next personal wrestling match with screening tests was the colonoscopy. I was seeing a gastroenterologist for some GI complaints, and we weren’t 5 minutes into our conversation before he recommended a colonoscopy. I argued that I was too young for a screening colonoscopy (I was 42 and they are recommended starting at age 50), and therefore was doubtful that anything too helpful would be found with the test. My suggestion was that a careful history and some blood testing might be the first place to start. My gastroenterologist acquiesced reluctantly.

As it turns out the blood testing was non-diagnostic and my symptoms persisted so I agreed to the colonoscopy. In this case I felt it was reasonable to do it since it was for diagnostic (not screening) purposes. I was quite certain that it would reveal nothing – or perhaps a false positive followed by anxiety, like my mammogram.

What it did show was some polyps that had a 50% chance of becoming malignant colon cancer in the next 10 years. I was shocked. If I had waited until I was 50 to start screening, I could have missed my cure window. The uneasiness about screening guidelines began to sink in. As a physician I had done my best to apply screening guidelines to myself and resist the urge to over-test, even with a healthy dose of natural curiosity. Yet I failed to resist screening, and in fact, my life was possibly saved by a test that was not supposed to be on my preventive health radar for another 8 years.

Screening tests are recommended for those who are most likely to benefit, and physicians and patients alike are encouraged to avoid unnecessary testing. But there are always a few people outside the “most likely to benefit” pool whose lives could be saved with screening, and the urge to make sure that’s not you – or your patient – is incredibly strong. I’m not sure if that’s human nature, or American culture. But a quick review of Hollywood blockbuster plots (where tens of thousands of lives are regularly sacrificed to save one princess/protagonist/hero from the aliens/monsters/zombies) testifies to our desperately irrational tendencies.

I am now biased towards over-testing, because my emotional relief at dodging a bullet is stronger than my cerebral desire to adhere to population-based recommendations. Knowing this, I will still try to avoid the temptation to over-test and over-treat my patients. But if they so much as hint that they’d like an early colonoscopy – I will cave.

Does that make me a bad doctor?

Mammography: Why This Test Is Both Imperfect And Recommended

A well-written and balanced article on mammography from USA Today may help move the conversation about this screening test away from hype and a bit closer to reality. The title – “Mammogram is ‘terribly imperfect’, though recommended.”

For women in their 40s, mammograms reduce the risk of dying from breast cancer by about 15%… But mammograms miss some cancers and raise false alarms about others, causing women to go through unnecessary follow-up tests… “We’re saying, ‘Mammography is a terribly imperfect test, but we’re recommending women get it,’” Brawley says. “The task force was saying, ‘Mammography is a terribly imperfect test, and Read more »

The Case For Mammograms: Friends And Family Might Be A Greater Influence Than Doctors

Most women in their 40′s believe they should have annual mammograms, regardless of what screening regimen their doctor might recommend.

So say researchers in Massachusetts who surveyed women (primarily white, highly educated) ages 39-49 presenting for annual checkups. They gave the women a fact sheet about the new USPSTF guidelines on mammogram screening in their age group, and asked them to read one of two articles either supporting or opposing the guidelines. The researchers then asked women about their beliefs, concerns and attitudes about breast cancer and mammogram screening. Here’s what they found –

  • Women overwhelmingly want annual mammograms – Close to 90% of women surveyed felt they should have annual mammograms, regardless of what their doctor might recommend.
  • Women overestimate breast cancer risks – Eighty eight percent overestimated their lifetime risk for the disease, with the average estimate being 37%. (The correct lifetime risk for breast cancer is 12%). This is consistent with previous research on breast cancer beliefs.
  • The media may not influence women’s opinions about screening guidelines – Read more »

New Pap Smear Guidelines: The Right Care Or Rationed Care?

The American College of Obstetricians and Gynecologists (ACOG) recently reiterated their position that Pap smears should be performed on healthy women starting at age 21. This is different from the past which recommended screening for cervical cancer at either three years after the time a woman became sexually active or age 21, whichever occurred first.

How will the public respond to this change?

Over the past year there have been plenty of announcements from the medical profession regarding to the appropriateness of PSA screening for prostate cancer and the timing of mammogram screening for breast cancer. Understandably, some people may view these changes in recommendations as the rationing of American healthcare. Read more »
