| Community cancer clusters are viewed
quite differently by citizen activists than by epidemiologists.
Environmentalists and concerned local residents, for instance, might immediately
suspect environmental radiation as the culprit when a high incidence of cancer
cases occurs near a nuclear facility. Epidemiologists, in contrast, would be
more likely to say that the incidences were "inconclusive" or the result of pure
chance. And when a breast cancer survivor, Lorraine Pace, mapped 20 breast
cancer cases occurring in her West Islip, Long Island, community, her
rudimentary research efforts were guided more by hope--that a specific
environmental agent could be correlated with the cancers than by scientific
method.
