Outdated Cancer Testing Methods May Pose Risk in Early Detection: Doctors

A coalition of physicians is criticizing Canadian cancer screening guidelines, arguing that they are outdated and failing to detect cancers early enough, thereby putting patients at risk. Dr. Fred Saad, a leading urological oncologist, emphasized the detrimental impact of delayed prostate cancer diagnoses during a press conference in Ottawa.

These guidelines, established by the Canadian Task Force on Preventive Health Care under the Public Health Agency of Canada, aim to assist healthcare providers in determining appropriate screening and prevention strategies for patients. The task force comprises a diverse group of healthcare professionals, including primary care physicians, nurse practitioners, and specialists.

However, Saad and fellow physicians affiliated with the Coalition for Responsible Healthcare Guidelines, which orchestrated the press conference, contend that the task force’s screening recommendations for breast, prostate, lung, and cervical cancers rely heavily on outdated research and contradict the perspectives of specialists in these fields.

For instance, the task force advises against widespread use of the prostate-specific antigen (PSA) test for men without a history of prostate cancer, a stance dating back to 2014, which Saad criticized as “obsolete” and “overly simplistic.” He argued that the recommendation stems from concerns about the potential harms of false-positive results, leading to unnecessary biopsies and treatments.

Saad argued that this rationale wrongly assumes that every individual with a positive PSA test will inevitably undergo a biopsy. “We have progressed far beyond the stage where every abnormal screening test results in a biopsy and every biopsy results in treatment,” he emphasized, highlighting the potential use of MRIs to circumvent certain biopsies. “Canadian men deserve the autonomy to determine what matters most to them, and family physicians must refrain from being misled by recommendations that defy logic and evidence.”
