Reducing Anxiety About False Positives

You have a mammogram but then the doctor calls you back for another test. Further tests show you are fine. There is no cancer. This is called a false positive result. It happens around one in 10 times. It’s more likely if you’re younger or if you have dense breasts. And if you’ve had ten annual mammograms the false positive rate can go as high as 50 percent.

Naturally, this scenario can cause a lot of anxiety and worry, which is perfectly understandable. Having to come face to face with the idea that you may potentially have cancer can be life-altering, and potentially traumatic for you and your loved ones. It should, however, be known that a false positive is very unlikely, and it’s recommended that you should still rely on regular mammograms.

"Mammography is the best tool we have to find cancer early, but it's not perfect," says Dr. Connie Lehman, Chief of the Breast Imaging Clinic at Massachusetts General Hospital and professor of Radiology at Harvard Medical School. So let’s put this into perspective: while a false positive is possible, it's not probable  and it shouldn’t scare you away from getting regular mammography screening.

Here are some tips to help ensure you get the most accurate test possible:

  1. Go to a large and experienced center that has a good record and reputation.
  2. Don’t wear deodorant on the day of your mammography. It can contribute to inaccuracies.
  3. Keep in mind that certain factors, like dense breasts, tattoos and breast implants, may also result in errors.
