Here's an easy way to make a charitable difference -- send an instant message.

Students at 35 colleges and universities are doing it, and it's turned into a great way to create awareness and raise funds for nine nonprofit organizations.

The organizations -- American Red Cross, Boys and Girls Clubs of America, National AIDS Fund, National Multiple Sclerosis Society, ninemillion.org, Sierra Club, Stopglobalwarming.org, Susan G. Komen for the Cure, and U.S. Fund for UNICEF -- receive a portion of advertising revenue every time a student has a conversation using instant messaging (or i'm).

It's all part of a Microsoft-sponsored campus program, and students get to choose their recipient organization each time they send an instant message.

There is no cap on the amount each group can receive, and Microsoft will make a guaranteed donation of at least $100,000 to each organization during the first year of the program.

Breast cancer survivor Catherine West was married to her husband, Jason, in a very public ceremony in May. The couple beat out 450 other couples battling in the ESPN Marriage Madness competition and celebrated with sports fans everywhere their beautiful union, inspired not only by their love for one another but also by the one-year anniversary of Catherine's double mastectomy for breast cancer.

What fans didn't know at the time of the wedding was that Catherine knew in her heart something was very wrong. And just after she returned from her Indianapolis 500 honeymoon, Catherine learned her breast cancer had returned.

The 37-year-old from Jupiter, Florida underwent three more surgeries, chemotherapy, and radiation and is happy to report her treatment is complete. She is also certain breast cancer came to her life -- twice -- so she could make a difference.

"This happened to me so I could help other people,'" said West, who volunteers her time for the West Palm Beach Race for the Cure, a 5K walk and run sponsored by Susan G. Komen For The Cure.

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.

I just ran three miles on my treadmill. I have never been the athletic one in my family. My sister is the one who was born with the athletic streak -- she played softball and lettered in tennis after giving the sport a try with no previous experience and may have helped her high school basketball team win a state championship if it weren't for the major knee injury she suffered just before the big game. I, on the other hand, was born with a streak that has something to do with hair, nails, and lots of shoes. I was never interested in sports, gym shorts, or sweating -- which is what makes running three miles a big deal for me.

I wish I had started running long ago -- because I really like it. I like the loud music that pumps through my MP3 player and the change in my cadence as each new song begins. I like the motivation of knowing I'm pushing my body and accomplishing a physical challenge. I like that my endurance improves with each mile I travel. I like the mental release and the thoughts that run through my head and the cleansing effect I get from running. And I like sweating.

It's possible running would not have appealed to me long ago, even if I had given it a try -- because times were different long ago. I was healthy. I was happy. And I had no reason to marvel at the possibilities of my body. Without a natural impulse for physical fitness and challenge, I was completely satisfied with the status quo. But now I have an acquired impulse -- because cancer has threatened the very body I once took for granted. And I want it to be strong. I want it to be healthy. I want it to stand up to any possible threat. So I run. And when I am not running, I look forward to running.

In just a few weeks, I will run in the 5K Making Strides for Breast Cancer event with my athletic sister. I will run by her side. With my loud music for motivation. With the inspiration that I am making a difference for my body and for women everywhere. With my gym shorts on. And a ball cap covering my hair. With sweat dripping down my face. I can't imagine a better feeling.

Tomorrow -- Monday, September 25 -- is the day when every dollar you spend at Chili's restaurants will be donated to St. Jude's Children's Research Hospital. So treat yourself to a meal out tomorrow -- and treat the kids at St. Jude's to some hope for a healthy future.

Donate All Our Profits Day is Chili's way of creatively conquering childhood cancer. This fundraising effort will benefit the development of Chili's Care Center -- a St. Jude's building dedicated to groundbreaking research on brain tumors. The center is scheduled to open in Fall 2007.

Chili's doors will be open for lunch and dinner tomorrow. So abandon your plans for cooking today and let Chili's cater to your every wish -- while you sit back, relax, and quietly make a difference in the lives of sick children.

I really do believe deep down in my gut that I will survive breast cancer -- that I will witness the wonder of my children growing up, that I will be married long enough that the years blur together, that I will live to a ripe old age. But I still have moments of doubt -- moments powerful enough to make me think I should not have a third child, just in case cancer comes back. To combat these moments -- that seem to surface more now that my treatment has stopped -- I try to keep busy, keep my mind occupied, keep living. My steps for surviving in the short-term include writing, journaling, exercising, relaxing, and spending time with family. But I also follow some steps for long-term survival -- steps that transcend the moment and give me purpose and direction. And here are seven of them.

There are many proud sponsors of the Susan G. Komen Breast Cancer Foundation Race for the Cure -- American Airlines, Yoplait, Ford, Kelloggs, New Balance, Ultra Quilted Northern, Remax, Sun Chips, and Zeta Tau Alpha Fraternity. And new this year is Coldwater Creek -- a company that specializes in women's apparel, jewelry, accessories, and gifts. Tucked away in Sandpoint, Idaho, Coldwater Creek offers merchandise through a number of retail stores across the country, through direct-mail catalogs, and through their website too. And now they offer something more -- the IN PINK Collection. Ten percent of each purchase from this collection of clothing and accessories goes directly to the Susan G. Komen Breast Cancer Foundation. And for each visor purchase, 100 percent of the profits are donated.

At Coldwater Creek, more and more women are being touched by breast cancer -- employees, co-workers, family members, friends, and customers. Breast cancer is a widespread disease that needs widespread support. So those at Coldwater Creek are reaching out and joining the ranks of supporters. And they are giving back to the many women who have supported them over the years. One small step by one company can make a world of difference.

Researchers report that the treatment success rate for younger men who undergo external beam radiation for prostate cancer is the same as it is for older men. This contradicts the traditional belief that radiation therapy is not considered a good choice for treating younger men because younger men are considered to suffer from more aggressive prostate cancer. But, according to the results of the study conducted by researchers at Fox Chase Cancer Center, the five-year-survival was 94 percent for men 55 or younger, 95 percent for those 60 to 69, and 87 percent for men 70 or older when men of all age groups received the same external beam radiation treatment.

The researchers of this study added, "that the results of this study cannot be used to prove that radiation is as a good or better than radical prostatectomy because the study didn't include a prostatectomy arm. However, other studies have shown that external beam radiation is equivalent to permanent prostate seed implantation and radical prostatectomy in patients with T1-2 prostate cancer."
