Eva Longoria took time out her busy acting and wedding-planning schedule to participate in the Spike for Hope charity volleyball tournament, which raises fund for PADRES Contra El Cancer (Parents against Cancer), supporting Latino kids and families that have been affected by cancer. According to Eva, she's not much of a volleyball player, but she couldn't refuse because she's actually the national spokesperson for the organization, whose motto is Yo Soy Esperanza (I am hope). That and she's naturally competitive.

I say kudos to her for helping raise some money from a worthy cause. How about you?

WOW, what a book -- a perfect guide for those just embarking on a medical journey and a valuable resource for people like me -- already surviving a major illness -- who wish to better manage their health care for all of time.

Author Laura Nathanson, MD, wrote What You Don't Know Can Kill You: A Physician's Radical Guide to Conquering the Obstacles to Excellent Medical Care in honor of the husband she lost after a series of misdiagnoses and for everyone wishing to prevent such tragedy in their own lives.

Nathanson offers readers techniques for identifying signs of misdiagnosis and misleading analysis of symptoms. She shares tips for preventing medical miscommunication, keeping safe in the hospital, and choosing health care plans without falling into the uncovered services trap.

The allure of this book is the easy, non-medical approach Nathanson uses as she urges everyone facing the medical world to take charge of an often inpenetrable system. For the patient who is no stranger to this world, Nathanson's words will ring abundantly true.

"When I look back on that long period of delayed diagnosis and how we were then and later bounced around from one medical specialist to another, the image that pops into my head is that of a slightly mad, grotesque volleyball game -- with the patient as the ball," she writes.

For the patient new to medical confusion, Nathanson's words will impart volumes of truth.

"Here's what I've learned, and what you must learn if you wish yourself and your loved ones to survive a bout with serious illness," she reports. "No matter who you are, physician or not, lucky or not; no matter how rich, famous, successful, good-looking, innocent, kindly or powerful; no matter how close and trusting the relationship you have with those providing your medical care -- you cannot rely on today's medical system to keep you healthy, safe and alive."

Amen.

Regular. Strenuous. Exercise. Memorize these three words. Live these three words. And abandon all thoughts of a fitness routine that is easy, moderate, or periodic.

Brisk walking, golf, and volleyball are considered moderate forms of exercise. Swimming laps, aerobics, and running are considered strenuous. And these are the activities we should be taking part in -- for the rest of our lives -- if we really truly wish to prevent breast cancer.

A new study, published in the February 26 issue of the Archives of Internal Medicine, shows women with a long-term history of engaging in strenuous exercise for more than five hours per week were 20 percent less likely to develop invasive breast cancer and 31 percent less likely to develop in situ breast cancer than those logging less than 30 minutes of strenuous exercise per week.

It seems strenuous exercise most affects estrogen-receptor negative breast cancer. But clearly, everyone can benefit from vigorous fitness training -- the American Cancer Society recommends moderate to strenuous exercise five days per week for at least 30 minutes each day -- and this is exactly why I am headed out for a run.
