Ribbon Colors for Cancer

I was looking at some cancer shirts and found that a lot of them have ribbons on them. I did a little looking and found the following:

• Blue Ribbon is for Colon Cancer (this would be my color).
  
• Black Ribbon is for Melanoma (my dad's color).
  
• Pink Ribbon is for Breast Cancer (Irene beat this one!).
