Camp Kesem, which gets its name from the Hebrew word for magic," is a transformative experience for most of the campers, who spend a week between Woodside and La Honda, amid the redwoods of the Santa Cruz Mountains. "A lot of them resist it before they come," said camp director Heather Paul, "and then they get here and find out it's not a cancer camp." Unlike other camps, which often forbid phone calls to and from parents, Camp Kesem has a hotline specifically for that purpose. "For a lot of them, the homesickness can be intense," Paul said, "especially if the parent was recently diagnosed." There had long been camps for children suffering from cancer and other life-threatening diseases, but until Stanford University's Hillel organization started Camp Kesem 13 years ago, there was almost no place for kids from families stricken with the disease to turn when they needed a break from watching their parents' suffering. "Kesem is a little haven where everyone understands and supports each other," said 15-year-old Juliane Bombosch, of San Bruno, whose mother was diagnosed with stage 4 breast cancer. Juliane this year is attending her fourth Kesem, and among the 120 campers and 75 counselors -- all undergraduate volunteers from Stanford -- are many who keep coming back until they exceed the age limit. There are 37 Kesems nationwide, with another five expected to be available next year, but because cancer is expensive, the camps remain free of charge -- and fundraising is a constant challenge.
