Breast cancer was studied over a 20-year period in Inuit populations i
n the Circumpolar region, A total of 193 breast cancers were observed
in women, The incidence increased from 28.2 per 100 000 in 1969-1973 t
o 34.3 per 100 000 in 1984-1988, However, the incidence is low, about
half what could be expected based on the rates in Denmark, Canada and
Connecticut (USA). The low incidence could be explained by the Inuit d
iet and other lifestyle factors, These benefits should be preserved, i
n particular in the young, to maintain a low breast cancer incidence.
