It seems screening for lung cancer doesn't save lives and it doesn't prevent advanced disease. But it does lead to potentially unnecessary and harmful treatment.

This isn't the final word on the use of CT scans to screen smokers and former smokers for the disease. But right now, the hope some experts had for the special X-rays to detect tiny lung abnormalities has been diminished by a large study that is still in the works. And until conclusive evidence says the screening is useful, the American Cancer Society will not endorse the test.

While CT screening did increase diagnosis and treatment -- those screened were three times more likely to be diagnosed with lung cancer and 10 times more likely to have lung surgery than predicted -- study co-author Dr. Peter Bach of Memorial Sloan-Kettering Cancer Center in New York says, "We don't see a trace of evidence that a single life was saved, that a single case of advanced cancer was avoided."

And because CT scanning led to more biopsies and surgeries, patients were put at risk for complications such as lung puncture, bleeding, and infection, according to Bach, whose work is published in the Journal of the American Medical Association.

"Getting screened for lung cancer with CT scanning is not only unproven, it's potentially a risky endeavor," he said.

Until an effective screening tool emerges -- possibly still years away -- experts say there is one surefire way to protect yourself from lung cancer. Stop smoking.

Pink Pony is the catch phrase for Ralph Lauren's initiative in the fight against breast cancer. Not only does Ralph Lauren support the fight by donating 10 percent of the proceeds from Pink Pony products to charity, but he has his own charity -- The Pink Pony Fund for Cancer Care and Prevention.

The Pink Pony Fund is a worldwide philanthropic effort. In the United States alone, Pink Pony recipients include Women's Cancer Research Institute at Cedars-Sinai in Los Angeles, Memorial Sloan-Kettering Cancer Center and Breast Cancer Research Foundation in New York City, Prevención, Inc., and Nina Hyde Center, both in Washington, D.C.

One of the premiere services provided by the Ralph Lauren Center for Cancer Care and Prevention is the patient navigator -- a concept created by Dr. Harold Freeman, medical director of the Center. Navigators assist patients and family members with access to health-care services and help them move with ease through the medical system. Navigators help patients with communication barriers, financial concerns, insurance difficulties, emotional issues, and more.

There is more than meets the eye when it comes to the pink pony. It is not merely a fashion statement that happens to kick a few dollars toward breast cancer research. It is a statement of true compassion and concern and commitment. It is a symbol of one man's hard work over the past 15 years to make a difference in the lives of women everywhere.
