First Nations Face Higher Kidney Cancer Rates in Canada

A team of researchers pulled data from the 2006 Canadian census health record to study kidney cancer among First Nations adults between 2006 and 2015. They connected census information to national cancer registries and death records. The purpose was to see how kidney cancer outcomes differed between First Nations people and the non-Indigenous population across Canada. The study covered a full decade, giving a broad view of trends.

During those ten years 445 First Nations adults received a kidney cancer diagnosis. Their incidence rate was nearly twice as high as that of non-Indigenous adults even after adjusting for age and sex. The elevated risk appeared in both men and women and it showed up in several different age categories. Researchers used Poisson regression to calculate relative risks and confidence intervals.

Mortality rates told a similar story. First Nations adults died from kidney cancer at higher rates than non-Indigenous adults whether the cause was cancer-specific or all-around. The disparity existed across both sexes and in many regional groups studied. All-cause mortality was also higher in the First Nations group.

Researchers say the findings point to a need for stronger prevention efforts and better chronic disease support. They also note that national cancer data often misses key details such as tumor stage which makes early detection harder. More uniform reporting could help create fairer outcomes for all groups. The study was published using the 1960 World Standard Population for age adjustment.
