Itscare and management have differed over time and have its identity.visibility, and meaning. Pick up the thread of history at its most distant5 end and you have “cancer the crab”—so named because its pain is likethe pinch of a crab’s claw. Premodern cancer is a lump that sometimesbreaks through the skin in ulcerations producing foulsmellingdischarges. The ancient Egyptians knew about many tumors that had abad oute, and the Greeks made a distinction between benign tumors10and evil ones. In the second century ., Galen reckoned that the causewas systemic, an excess of sadness or black bile, one of the body’s four“humors” brought on by bad diet and environmental circumstances.
