Breast cancer (BC) is a devastating disease in female around the world causing significant health care burden in both developed and developing countries. In many cases BC has shown resistance to chemotherapy, radiation and hormonal therapy. Development of new, cost effective, affordable treatment method is the need of hour. Chemical compounds isolated from plants are often biologically active and is attracting the attention of scientific community. Different in vitro and in vivo studies have shown a potential role in reducing the risk of cancer metastasis. Large number of phytochemicals are considered to regulate several molecular and metabolic processes like cell cycle regulation, apoptosis activation, angiogenesis and metastatic suppression that can hinders cancer progression. An extensive review of literature has been conducted to underline the key phytochemicals and their mechanism of action. This review article has discussed in detail the regulatory roles of phytochemicals, their analogs and nanoformulations and the probability of using phytochemicals in therapeutic management of BC. Finally, current limitations, challenges and future perspectives of these phytochemicals are also critically discussed.
