A Review on Novel Breast Cancer Therapies: Photodynamic Therapy and Plant Derived Agent Induced Cell Death Mechanisms

Anticancer Agents Med Chem. 2016;16(7):793-801. doi: 10.2174/1871520615666151026094028.


This review article presents an extensive examination of risk factors for breast cancer, treatment strategies with special attention to photodynamic therapy and natural product based treatments. Breast cancer remains the most commonly occurring cancer in women worldwide and the detection, treatment, and prevention are prominent concerns in public health. Background information on current developments in treatment helps to update the approach towards risk assessment. Breast cancer risk is linked to many factors such as hereditary, reproductive and lifestyle factors. Minimally invasive Photodynamic therapy (PDT) can be used in the management of various cancers; it uses a light sensitive drug (a photosensitizer, PS) and a light of visible wavelength, to destroy targeted cancer cells. State of the art analyses has been carried out to investigate advancement in the search for the cure and control of cancer progression using natural products. Traditional medicinal plants have been used as lead compounds for drug discovery in modern medicine. Both PDT and plant derived drugs induce cell death via different mechanisms including apoptosis, necrosis, autophagy, cell cycle regulation and even the regulation of various cell signalling pathways.
