An oncology ward is a battlefield, and there are definite hierarchies of command. The patients, they're the ones doing the tour of duty. The doctors breeze in and out like conquering heroes, but they need to read your child's chart to remember where they've left off from the previous visit. It is the nurses who are the seasoned sergeants -- the ones who are there when your baby is shaking with such a high fever she needs to be bathed in ice, the ones who can teach you how to flush a central venous catheter, or suggest which patient floor might still have Popsicles left to be stolen, or tell you which dry cleaners know how to remove the stains of blood and chemotherapies from clothing. The nurses know the name of your daughter's stuffed walrus and show her how to make tissue paper flowers to twine around her IV stand. The doctors may be mapping out the war games, but it is the nurses who make the conflict bearable.
