For the past month, pink ribbons have been everywhere — along with bracelets, shoes, t-shirts, even pink KFC buckets.

Yet for all this colorful breast cancer awareness, somehow we're still not talking about one of the key things we can do to prevent the disease: stop eating, drinking and breathing cancer-causing chemicals.

Sounds like a good idea, right? Scientists tell us there's plenty of evidence linking chemical exposure with cancer. Astonishingly, a conversation about this kind of prevention simply wasn't part of the mix.

There were a few notable exceptions. Our friends at Breast Cancer Action, The Breast Cancer Fund and Clean Water Action all made a strong case for moving beyond awareness toward prevention. But otherwise the issue was largely ignored — despite a recent report from the President's Cancer Panel finding that Americans are exposed to too many pesticides and other chemicals that cause cancer.

The Cancer Panel scientists also found that previous estimates of the role environmental contaminants play in causing cancer were much, much too low. They reported startling long-term impacts of exposure, like the fact that girls exposed to DDT during puberty were 5x more likely to have breast cancer in middle age.

They were so concerned by their findings that they went way out on a limb and actually called on President Obama to do something about it, urging him to "use the power of your office to remove carcinogens and other toxins from our food, water and air."

Sadly, the White House appears to be ignoring the Panel's recommendations.

This year's presidential proclamation marking National Breast Cancer Awareness Month includes not a word on the role of environmental contaminants in causing the disease.

"Our sense is that the recommendations in a remarkable report are being actively ignored by the Administration," writes PAN board member Dr. Ted Schettler and his colleagues Dr. Sandra Steingraber and Dr. Richard Clapp after their meeting with White House staff about the report. "A great opportunity to prevent cancers through better environmental protections may be lost."

Meanwhile, the science keeps rolling in. Here are just a handful of recent, interesting examples:

• University of California's Breast Cancer & Chemicals Policy Project published Pathways to Breast Cancer, a report proposing new ways to evaluate how chemicals contribute to breast cancer.
• 50,000 women have enrolled in the national "Sister Study," which tracks women whose sisters have had breast cancer and evaluates the contribution of both genetic and environmental factors to the disease.
• Scientists in the UK reported that cancer was virtually nonexistent in the ancient world, based on examination of almost a thousand mummies from Egypt and South America.
• The Breast Cancer Fund's annual State of the Evidence report (mentioned here a couple of weeks ago) looks carefully at the latest science about the links between chemical exposures and breast cancer.

We all know the stakes are high. One of every 8 women can expect to develop breast cancer. And while survival rates are improving, it's still the leading cause of death among women in their late 30s to early 50s. As anyone who's life has been touched by the disease knows, anything we can do to prevent the devastation of cancer should be a national priority. Now.

Next week I'll travel to Washingon DC to deliver PAN's petition urging Mr. Obama to listen to his cancer scientists. If, like me, you're baffled at the lack of response from the White House and want your voice heard, please add your name to the petition today. Pass it along to friends and family too. The more voices the better.
