Prescription weight-loss drug Xenical hit drugstore shelves on Friday with a new name -- Alli (pronounced: "Al-eye") and with a new non-prescription strength. The newly-named drug is to be more effective with less unpleasureable side effects. Still, there's a problem surrounding this drug, regardless of its name. It's thought to cause colon cancer.

The nonprofit group Public Citizen says Alli, made by GlaxoSmithKline, has been shown in mice studies to cause pre-cancerous lesions in the colon. Since there are no long-term studies on humans, this group believes the FDA should not have approved the drug for non-prescription use. It's not clear whether or not the pre-cancerous spots will lead to colon cancer but the mere suggestion that it might is enough, says a Public Citizen spokesperson.

"What we do know is that these lesions occur much more frequently in people who do get colon cancer," he said. "Why do we recommend that everyone get a colonscopy at the age of 50? Because you pick up on these polyps when you do one. And, even though not all of the polyps are pre-cancerous, no (doctor) does a colonscopy without removing every single polyp that is found. And you do this because you know if you don't, it greatly increases the chances of getting cancer."

Glamour's October magazine features stories about breast cancer survivors. Cancer Vixen Marisa Acocella Marchetto, cartoonist for Glamour and The New Yorker and author of Cancer Vixen: A True Story, is profiled. And another survivor -- young mom Kelly Corrigan who authors her online journal Circus of Cancer -- is highlighted. And Allison Briggs, diagnosed with breast cancer at the age of 26, shares her photo journal with readers who learn from all three survivors that more and more, women are sharing their cancer journeys in very public ways.

Allison -- Alli -- could not sleep the night she was diagnosed with breast cancer so she sent her boyfriend to the store for medication to calm her upset stomach. While he was gone, she noticed a camera sitting on the bedside table. She had an overwhelming urge to start snapping photos. So she took some self-portraits, had her boyfriend take some more when he returned home, and decided that night she would document her journey through photographs. She wanted to remember this phase of her life -- even though she had no idea how it would turn out.

Life is turning out just fine for Alli, who has rallied a support team called The Rack Pack, a group of women who aim to make a difference -- all because of the inspiration and strength they receive from their friend Alli. They are participating in the Susan G. Komen Breast Cancer 3-Day, 60-mile walk in San Diego November 10-12. They sell Rack Pack t-shirts. They offer e-mail notification of exclusive Rack Pack events. They share updates about Alli. They never stop trying to make a difference -- for Alli and for women everywhere fighting breast cancer.
