Celebrities have a way of motivating the public to take action. They help dictate fashion trends and set standards for mostly unattainable body shapes and sizes. They add hype to political views and philosophies and make influential statements about all sorts of issues. Like breast cancer. With its backing from celebrities like Melissa Etheridge and Sheryl Crow and Kylie Minogue — all breast cancer survivors who are speaking out and raising awareness — breast cancer has burst onto the media scene and is receiving powerful, positive attention. Kylie Minogue’s public diagnosis spurred so many women into getting their breasts checked that the Medical Journal of Australia reports a 40 percent increase in bookings for mammograms. But sometimes, celebrity diagnoses don’t elicit a response at all.

Italian tenor Luciano Pavarotti was diagnosed with pancreatic cancer last month — yet the announcement barely registered on the public’s radar. Perhaps he does not command the same kind of reaction as pop singers do. Or perhaps it’s the type of cancer that keeps his public battle on the sidelines.

The breasts are a visible icon of femininity — out in the forefront for all to see. And so the issue of breast cancer is in the forefront. The pancreas, on the other hand, are hidden behind the stomach and are out of sight — and out of mind. When Apple chief executive Steve Jobs was diagnosed with pancreatic cancer in 2004, he didn’t even know where to find his pancreas. And so this organ does not attract much fanfare — and therefore does not attract the funding and research that breast cancer does. Which is sad because this cancer is not just hidden inside the body. It’s also a hidden killer. It can’t be felt like breasts can be felt. And there is no easy way to detect it, like with mammogram and other imaging techniques. Often a diagnosis of pancreatic cancer — the fourth leading cause of cancer death in Western societies — comes with a death sentence. And more and more, breast cancer diagnoses come with promising expectations of survival.

We may not know as much as about pancreatic cancer as we do breast cancer. But there are some behaviors that may contribute to this deadly disease. So in the spirit of prevention, consider this:

• If nobody smoked, 25 percent of pancreatic cancer cases wouldn’t happen.
• Alcohol consumption can increase the risk by 15 times.
• Some studies link high meat consumption and low vegetable consumption to incidences of pancreatic cancer.
• Folate, the B vitamin in green leafy vegetables, oranges, legumes, and whole grains seem to reduce the risk. But folate supplements don’t seem to have the same healthy effect.
