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.

Cancer patients receiving treatment at the Arizona Cancer Center in Tucson will walk through the doors of a new building -- the Fasseas Cancer Center-- beginning tomorrow morning.

The new center, named after major donors Peter and Paula Fasseas, is built on the skeleton of a defunct Tucson hospital. It took 16 months to build and cost an estimated $30 million. And now the comprehensive cancer center is ready for use.

More than 800 cancer patients have appointments during the first week, and 110 medical staff will relocate to the new clinic that has been called the crown jewel of new University Medical Center North Campus and one of the most modern cancer treatment centers in the United States.

The new two-story clinic -- to be joined later by facilities for radiation oncology, ambulatory surgery, imaging services, and a Ronald McDonald House for pediatric patients and their families -- will feature patient support groups, counseling, therapeutic massage, a healing garden, a resource center, and a salon to help patients cope with hair loss and other side effects of cancer treatment.

A formal grand opening for the new clinic is planned for February 18.

I remember as a college student walking into the shower in the community bathroom of my residence hall and noticing a plastic placard hanging from the neck of the shower faucet. It listed step-by-step instructions for completing a self-breast exam. I paid no real attention to this sign, took my shower, and went on with my day filled with classes and friends. I was 19 years old and believed breast cancer was no concern for me at this young age. I'm sure I believed breast cancer would never be a concern for me at all -- ever.

I found my own lump in the shower 18 months ago -- a small, pea-sized, hard lump that I felt when washing and examining myself for anything out-of-the-ordinary. I think of that placard often and hope more young women are paying attention to these life-saving tips.

A friend asked me recently to help him locate these signs for the college students he works with. I found them, thanks to the Susan G. Komen Breast Cancer Foundation, and I am thrilled that they hang in the showers on at least one college campus.

Although I did not pay attention in the showers on my own college campus, these placards did influence me -- because 16 years later, I remember them. This is the very essence of awareness, I think.
