"In the struggle against cancer, art is a tool of survival," writes curator Gerald Silk in his introduction to Confronting Cancer Through Art. This art exhibit (at the University of Pennsylvania's Arthur Ross Gallery) and "virtual gallery" include works by over a hundred artists, many of them cancer survivors or artists responding to the illness of a family member or friend. The work ranges from visceral expressions of pain to affirmations of survival. The image from Kindertotentanz, above, is by David Aristotle Haughton, who writes:

"Ten years ago I trained as pediatrician on the cancer ward of a children's hospital. I witnessed children in pain and children dying. The anger and helplessness I felt compelled me to begin the Kindertotentanz: a series of etchings, watercolors, and oils that expressed my ambivalence toward modern medicine. In this ongoing series of works I have an outlet; they drain my rage. They shout what I cannot say aloud."
