I find the page too busy. I suggest a home page that is simpler, less crowded and with bigger font and "buttons" for pages.
Look & Feel
I was looking at the site and it would nice to log on to site tailored to me and my needs or interest. Like it could have links on it that I am interested in: Cancers Types, New treatment options, research, rallies, cancer news and even request friends who may be going through the same battles as you. You could always post info and start blogs and even have alerts to keep you informed.
