There is a wonderful website called Stand Up To Cancer (SU2C) where for only one dollar you can launch a star to honor someone who has had a cancer diagnosis. I launched one for my Dad today. He passed in 2003 to a rare form of cancer called Esthesioneuroblastoma.
You can leave messages on stars that were already created or launch one of your own. Either way, it's a nice way to pay tribute to someone you care about.
