Breast cancer is most frequently encountered cancer in women. It comprises 18% of all cancers in women. Risk for incident breast cancer is increased by advancing age (Siegel et al., 2012). Clinical behavior is characterized with a prolonged natural course and heterogeneity. Patients diagnosed as breast cancer carry metastasis risk for long periods and definition of cure is problematic. Treatment decisions depend on tumor characteristics and treatment response (Sotiriou et al., 2003; Sezer et al., 2011).
