Abstract

Background: In the present study, we examined breast (BCa) and colorectal cancer (CRC) incidence and mortality and stage at diagnosis for First Nations (FN) individuals and all other Manitobans (AOMS). Methods: Several population-based databases were linked to determine ethnicity and to calculate age-standardized incidence and mortality rates. Logistic regression was used to compare BCa and CRC stage at diagnosis. Results: From 1984–1988 to 2004–2008, the incidence of BCa increased for FN and aom women. Breast cancer mortality increased for fn women and decreased for AOM women. First Nations women were significantly more likely than aom women to be diagnosed at stages IIIIV than at stage I [odds ratio (OR) for women ≤50 years of age: 3.11; 95% confidence limits (CL): 1.20, 8.06; OR for women 50–69 years of age: 1.72; 95% CL: 1.03, 2.88). The incidence and mortality of CRC increased for FN individuals, but decreased for AOMS. First Nations status was not significantly associated with CRC stage at diagnosis (OR for stages III compared with stages IIIIV: 0.98; 95% CL: 0.68, 1.41; OR for stages IIII compared with stage IV: 0.91; 95% CL: 0.59, 1.40). Conclusions: Our results underscore the need for improved cancer screening participation and targeted initiatives that emphasis collaboration with fn communities to reduce barriers to screening and to promote healthy lifestyles.
