title: Cancer risks in Swedish Lapps who breed reindeer.
abstract: Cancer risks during the period 1961-1984 were studied in a cohort of 2,034 Swedish reindeer-breeding Lapps, a unique group whose culture and life-style differ considerably from those in the rest of the Swedish population. A total of 100 cases of cancer were observed versus 163 expected. Statistically significantly decreased risks were found for cancers of the colon, respiratory organs, female breast, male genital organs, and kidneys, and for malignant lymphomas. The stomach was the only site with a significantly increased risk. Reindeer-breeding Lapps have ingested fallout products via the lichen-reindeer-man food chain since the 1950s. However, no increased risk was found for the cancer sites considered to be most sensitive to radiation.
