But there are dozens of different ribbon colors representing each type of cancer. Breast cancer organizations have done a great job of promoting pink ribbons, but there are more common cancers that have their own ribbon colors that deserve recognition as well.

Skin cancer is represented by a black ribbon, lung cancer by a white ribbon and prostate cancer is light blue. The first documentation of symbolic ribbons comes from medieval times.
