I. Introduction
Annually, more than a million women are diagnosed with breast cancer, 14% of which resulting in death. Breast cancer has high incidence and prevalence rates, being a relevant disease and considered as a public health problem [1]. Considering surgical intervention, two different treatment procedures are possible: mastectomy or BCCT. While the mastectomy procedure entirely removes the breast, BCCT excises the tumour together with a margin of cancer free breast tissue [2]. This conservative approach allows a local intervention on the disease and provides similar survival rates to mastectomy. Moreover, best aesthetic results are achieved [3].
