Breast cancer in Brazil: Screening program and surgical approach.

Background: Screening mammography for breast cancer (BC) is a current strategy that reduces the mortality of BC by up to 30 %. Although mastectomy has been an important component of treatment for decades, conservative surgery (lumpectomy) has become the gold-standard approach for most cases, yet it depends on early detection of the BC.

Methods: This was an epidemiological study performed through DATASUS (2010-2018).
