Annual Screening Does Not Reduce Risk Of Death From Breast Cancer

And experts know that women with small breast cancers have a better chance of long-term survival than women with large breast cancers.

“So stopping mammography screening will not result in lives lost, but lives lived with greater quality of that life,” he added.

What did other studies find?
In 2013, Medical News Today reported on a UK-based study that also found breast cancer screening does not reduce deaths from the disease.

But the findings of this study do contradict findings from some other similar studies. A Swedish study attributed a 31% reduction in mortality to mammography. But the authors of the Canadian study think that the Swedish trial was flawed and the difference is down to “an initial imbalance of the compared groups, not a benefit of screening mammography.”

A large systematic review of data from 1976 to 2008 also had different findings to the Canadian study, estimating that 31% of all breast cancers were over-diagnosed. The Canadian researchers think this difference was due to that review taking a wider age range into account than their study, which looked at women between the ages of 40 and 59 only. They think that over-diagnosis is more common in people older than this, as there are more potential causes of death as individuals age.

The researchers also admit that the result of the Canadian study may not be generalizable to all countries.

Rationale for mammography should be ‘reassessed’
Although Prof. Miller and his team assert that education, early diagnosis and clinical care remain priorities in treating breast cancer, they say that mammography does not result in a reduction in breast cancer-specific mortality for women aged 40-59 beyond that of physical examination alone or usual care in the community.

The authors say that annual breast cancer screening should be urgently reassessed by policy makers, but they anticipate resistance from medical groups with “vested interests.”

Rather than annual breast screenings, the authors of the study would like to see funding diverted into better public education programs to convince women to seek skilled advice if they detect an abnormality in their breast, and professional education programs that ensure doctors are familiar with the latest advances in research.
