On December 7, the Institute of Medicine (IOM) released a report on breast cancer and the environment. The report (downloadable for free) was commissioned by the Susan G. Komen foundation and was written by a committee of experts who spent over a year reviewing and summarizing scientific evidence. The committee adopted a broad definition of “environment” to include anything that didn’t involve factors inherited through DNA.
The 360 page report was widely covered in the media yesterday and many of the headlines focused on personal responsibility for avoiding the “environmental” factors identified as being most strongly linked to breast cancer. The advice will not be new to most of you – don’t smoke or hang out around smokers, don’t drink excessively, don’t take hormone replacement therapy, avoid unnecessary medical radiation, and maintain your ideal weight and get regular exercise.
However, with a few exceptions, most of the news articles did not delve deeper into the report nor discuss some of its more signficant recommendations. Unfortunately, the impression that many of the headlines left was the ability to avoid breast cancer is in your control, if you just live a healthy life. However, the report was much richer than this and there were some important observations and recommendations which were left out of the mainstream media reports that I think are important to point out.
First, for the Komen foundation, this report is a significant step forward in the turning the conversation from how to cure breast cancer to how to prevent it. While we have made great strides in better detection and treatment of cancer, there has not been much of an emphasis on how to prevent breast cancer in the first place or in identifying factors which might cause it. This report starts that conversation at a national level.
