Genetics and Breast Cancer - Oncologists Perspectives.

Breast cancer is the most common cancer in women worldwide. The clinical outcomes of which, have improved in the past decade, primarily due early diagnosis and multimodal management. Understanding of the disease biology with findings from omics-based research and molecular genetic characterization of the disease has been an important component of the therapy in the past 10 years. There is a need to understand the variations in individuals at the molecular level to enable in sub-classification of the different disease phenotypes and if possible to tailor the treatment to the patient. This article attempts to review the beneficial role of genetics in various facets of breast cancer management, in modern scientific medicine.
