Cancer is the second largest cause of mortality worldwide. The prevention and treatment of cancer progression still has a great deal of room for improvement despite enormous advancements. When having chemotherapy, a number of unfavourable side effects might possibly occur. Unfavorable side effects may be reduced by using natural therapies, such as using cancer therapy components derived from plantsCurrently, a small number of plant-based products are used to treat cancer. However, a variety of plant substances have demonstrated highly promising anti-cancer properties in vitro but have not yet been tested on people.. The effectiveness of these plant compounds in treating human tumours needs to be further investigated. The focus of this review will be on the numerous conventionally used medicinal herbs and the chemical substances they contain that have recently proved promise as anticancer agents. It will examine the possible mechanisms of action for such compounds. The medicinal plant and patents for cancer chemotherapy and chemoprevention are covered in this article. Future research emphasizing on the natural anticancer agents which can provide a new horizon in cancer treatment, This will significantly increase the likelihood that cancer patients will survive.
