Abstract

In recent decades, breast cancer cases have increased steadily worldwide. However, the increases do not hold across all demographics and breast cancer cases in low and middle income countries have increased much faster than the global trend. Colombia is not an exception. Breast cancer was the most frequent tumor and the second cause of cancer-related deaths in women in 2008, with an estimated of 6,700 new cases and 2,100 deaths. We present here an analysis of breast cancer mortality rates and trends in Colombia, over the period 1985–2008. We studied overall and age-specific changes in breast cancer mortality using change-point Poisson regression models. Between 1985 and 2008, there were 32,375 breast cancer deaths in women in Colombia. Breast cancer mortality increased since 1985, although the annual increase varied between age groups and socioeconomic levels. Only in women aged 45–64 years old that live in areas of high socioeconomic levels, breast cancer mortality was stable or decreasing. Hence, successful cancer control is possible in middle income countries, as shown by the progress observed in certain groups. The development of an integrated strategy of early detection and early access to proper treatment, suitable for areas with limited resources, is an urgent necessity.
