Wage -specific assessment of mammography screening in Brazilian women

Mammography is an inexpensive examination that has become a standard screening method thanks to its cost-effectiveness. Due to an enormous cost escalation of cancer treatment over the last years, the assessment of this method, especially in the settings of an emerging country, is a matter of serious concern.

A search within the national health database was conducted registering the data with nation- wide coverage. Data collection and analysis was commenced in 2010 with referrence to the year 2008 as the most recently updated period. The obtained information on mammography screening among Brazilian women was evaluated by subdividing the data in four groups according to socioeconomic status of the subjects. The study population was estimated to comprise about 2 million individuals.

More than 45% of Brazilian women older than 40 years of age have never undergone a mammography. The figures correlated with the income level, reaching an astonishing number of 62.2% in a group of patients with the lowest income level.

Mammography has proved effective in early detection of breast cancer in women. This study suggests that the lack of compliance in breast cancer screening in Brazil, pronounced especially in low- income families, may contribute to the increasing mortality rates associated with the disease.
