False-Positive Mammogram Worse Than the Real Thing for Many Women

For many women, getting a false-positive result in a breast cancer screening can be worse than actually having cancer — at least when it comes to their mental health.

As such, doctors are calling for women to receive more information about the pitfalls of breast cancer screening, as well as the benefits.

A study published online by BJS, the British Journal of Surgery, shows that patients with false-positive results – where the mammogram is abnormal but no cancer is present – had to undergo more diagnostic procedures than women with breast cancer before they were given the all clear.

Researchers from The Netherlands spoke to 385 women with abnormal mammogram results – 152 were subsequently diagnosed with breast cancer, but the other 233 had false-positive results and did not have cancer.

“Common sense tells us that early detection of breast cancer is good and most screening programs have been successful in reducing breast cancer deaths,” said lead author Lideke van der Steeg, M.D.

“However, while some women truly benefit from early detection, others experience harm and unnecessary anxiety. The women who received false-positives in our study experienced a significant reduction in their quality of life, especially if they were prone to anxiety, and the effects of this lasted at least a year.

“In fact, women who had a tendency to be anxious fared much worse if they received a false-positive – which is estimated to happen in 60 per cent of abnormal mammograms – than if they were actually diagnosed with breast cancer.”

Women with abnormal mammograms attending three hospitals over a five-year period were invited to participate. Their quality of life (QoL) was assessed using the World Health Organization’s Quality of Life instrument 100, which assesses QoL in six domains – physical health, psychological health, level of independence, social relationships, environment and spirituality.

Clinical data was obtained from the women’s medical records and they were also asked to complete questionnaires providing demographic information such as age, marital status, education and socioeconomic status.

Women in the breast cancer (BC) group were significantly older than the women in the false-positive (FP) group – 60.2 years versus 57.3 years. They also had larger tumors than the FP group – 17.4mm versus 9.9mm.

The key factors influencing QoL scores differed between the two groups:

      • Trait anxiety (a tendency to experience anxiety) accounted for up to 55 percent of the variance in the QoL score in the FP group. It reached this peak at three months, but was similar at months one and 12 (43 per cent and 40 percent respectively).

     

        • State anxiety (temporary anxiety due to a specific situation) accounted for up to 46 percent of the variance in the BC group. It peaked at six months, but was similar in months one and 12 (32 percent and 34 percent).

       

        • State anxiety levels did not significantly influence QoL in the FP group and trait anxiety levels did not influence QoL in the BC group.

      Significantly more diagnostic procedures, including biopsies, were needed in the FP group to reach a final diagnosis. Only 14 percent of the BC group required four procedures – the other 86 percent required three – while 32 percent of the FP group required more than three.

      Fifty-five percent of the FP group returned to the outpatient clinic in the first year, some as many as eight times.

      The authors believe that the anxiety and lower QoL experienced by women in the FP group were soley due to the recall after screening and the subsequent diagnostic procedures.

      “The decision to participate in a screening program requires balanced information about the potential benefits and dangers,” said van der Steeg.

      “Women often overestimate their risk of breast cancer and the material provided by health care professionals and government agencies often focus on the positive aspects of screening and are not always objective.

      “Women deserve more balanced information to help them to choose whether or not to accept a breast screening invitation. This should not only cover the supposed benefits, but explain the potential side-effects of a false-positive, such as the increased feelings of anxiety and reduced QoL found by our study.”
