ABSTRACT
Breast cancer is nowadays the most common malignancy among women in developed countries [1], being the third most common cancer in Europe after lung and colorectal cancers. The high prevalence of breast cancer (out of every 10 women, 1 will develop a breast malignancy during her life) promotes that an important number of women suffer the consequences of this disease, which vary from breast surgery to death. More than 15,000 cases of breast cancer are diagnosed each year in Spain. In 2012, this disease caused around 6,000 deaths [2].
