Abstract
INTRODUCTION
Colombia has a population of roughly 49 million people of predominantly Mestizo ethnicity. Cancer has become a growing public health problem in Colombia with nearly 71,000 newly diagnosed malignant tumors per year. It is expected that by 2035, 150,000 new cases of cancer will be diagnosed, making Colombia an intermediate country with regards to global cancer incidence according to IARC.
METHODS
Epidemiological data on breast cancer is scarce and varied due to multiple sources of information. These numbers are obtained thru population-based cancer registries that represent 4 distinct regions of the country. Other data originate from non-governmental institutions and healthcare providers within Colombia. The Colombian National Cancer Institute publishes a Cancer Mortality Atlas annually.
RESULTS
Local cancer registries have shown increases in breast cancer incidence in Colombia. In 2007, age-standardized incidence rate was 27.8 per 100,000 persons increasing to 49.7 cases per 100,000 persons in 2012. Approximately, 2200 women die every year in Colombia due to breast cancer with rates increasing historically, but now are stabilizing. Advanced breast cancers are most frequently found among women without health insurance, while early breast cancers are usually found among working women and those covered by private health insurance. Early breast cancer screening was made mandatory as public policy in the year 2000. However, only 30% of health care coverage was reported, translating to very low coverage by opportunistic screening programs with only 33% of women having had a mammography. In 2012, a National Cancer Control Plan was planned and implemented. It aims to increase early stage cancer diagnosis, increase biannual screening coverage, and guarantee timely access to diagnosis and treatment. A national health survey in 2015 showed only 48% of women had an annual mammographic screening. Multiple disparities have been found with regards to screening and early diagnosis such as economic strata, health insurance coverage, origin, and accessibility. Specifically, data shows that 23% needed to travel in order to obtain access to mammography. Often it is necessary for some patients to sue healthcare insurance systems to obtain specific health care, causing an increase in time to diagnosis and treatment. In 2016, on average a 90-day period was reported from time of onset of symptoms to suspected diagnosis of breast cancer, while the time to the initiation of treatment was 100 days for chemotherapy and close to 120 days for surgery.
DISCUSSION
These data serve to impact the landscape of breast cancer and improve patient outcomes in Colombia. While the National Cancer Plan has led to major changes, a big challenge remains related to the delays between suspicion of breast cancer and diagnosis and treatment. Quality of care provided by private and public insurance administrators is also of concern. General practitioners should receive more detailed training in breast cancer detection and management. The healthcare system should provide quality cancer care with urgent improvement in mammography, especially in more rural areas. Widely, more timely and appropriate follow-up is needed.
