I'm not sure where I was headed professionally before cancer. I knew I was happy as a stay-at-home mom, and I didn't give much thought to what might come next. I was pretty certain I would not do what I did before kids -- college administration and counseling -- and that's as far as I'd gotten in my decision-making process.

It seems cancer would have further confused my future intentions. But it didn't. Instead, it led me in a direction I may have otherwise never discovered. First, it guided me to a part-time position at my kids' preschool. Just after surgery, chemotherapy, and radiation and in the midst of Herceptin breast cancer treatment, I felt a strong urge to reenter the world of the living. One day as I was dropping off my oldest child at his Pre-K class, I noticed an advertisement on the doors of the school. I inquired within -- and got a job working two afternoons per week.

The job was a blessing. I got to see my kids while I worked, interact with loving adults and children, and distract myself from the darkness of cancer.

I have made on-line visits to Wikipedia many times -- mostly for information on cancer. And what I've found are endless resources, thoroughly-covered topics, and material that is easy to read and easy to understand. Wikipedia, a free on-line encyclopedia -- where readers can participate in editing and changing content -- offers information on just about any topic you can imagine. And here are seven stops you might make in pursuit of cancer-related material.
