ABSTRACT

Breast cancer is the most common cancer among women and is second only to lung cancer as a cause of cancer-related deaths in women (Jemal et al., 2004). Interpretation of cancer incidence and mortality rates in a defined population requires an understanding of multiple complex and interacting factors. For example, many studies in the literature report association between late-stage breast cancer diagnosis and covariates, such as socio-economic status, access to health care, marital status, ethnicity and neighborhood of residence (Farley and Flannery, 1989; Barry and Breen, 2005; MacKinnon et al., 2007).
