There is a new look of the site.  I hope you find it more professional looking.  I picked the different colors for the image because there are so many different types of cancer and they are each represented by a color.  I soon hope to develop my own image that will represent each color of cancer.  Let me know what you think of the new site design.  I will also be offering different site themes for the users.  I should have them ready early 2008.
