Determinants of choice of surgery in Asian patients with early breast cancer in a middle income country.

Background: Breast-conserving surgery (BCS) plus radiotherapy is equivalent to modified radical mastectomy (MRM) in terms of outcome. However there is wide variation in mastectomy rates dependent both on tumour and patient characteristics.

Objective: This study aimed to assess the determinants of surgery choice in Asian patients with early breast cancer in a middle-income country.
