Breast cancer (BC) is the most common cancer in women in India. In every 4 minutes in India, one woman is diagnosed with breast cancer (BC), and in every 13 minutes one woman dies of it. Hence, a detailed and deep understanding of the disease progression is much needed for successful therapeutic intervention. One major stage in cancer progression is metastasis in which tumor cells leave their original site and recolonize into a new tissue. For metastatic BC, prognosis is generally poor.
