ABSTRACT
Although breast conserving surgery is the standard of care for patients with localized breast cancer in high-income countries, little is known about its use in developing countries, where disparities in access to treatment may lead to an increased use of mastectomy. We examined the use of breast conserving surgery at a Mexican cancer center after the implementation of a public insurance program aimed at providing coverage for previously uninsured patients. Between 2006 and 2016, 4519 women received surgical treatment for breast cancer, of which 39% had early-stage disease. The proportion of patients treated with breast conserving surgery increased from 10% in the 2006-2009 period to 33% in the 2013-2016 period, with most of this increase occurring among women with early-stage disease (17-52%). Improving access to care and reducing the financial burden of breast cancer in developing countries may lead to an increased use of breast conserving surgery.
