Abstract

Cancer is the second leading cause of death in the world. It is essential to find the best strategy and solution as soon as possible. Many therapies such as targeted therapy, immunotherapy, surgery, chemotherapy, radiation therapy, hormone therapy and stem cell therapy are used to treat cancer with new strategies. Still, we need a more advanced strategy to treat it. The use of bacteria in cancer treatment is a new approach. Bacteria can be used as a therapeutic agent. They are used to deliver a nanoparticle to a specific targeted site. The more important thing is that encapsulated bacteria can protect themselves as well as help to reach nanoparticle to its target successfully. Magnetotactic bacteria (MTB) can sense the nutrients and reach there with the help of flagella; it can swim easily through the vascular system. If the nutrient uptake capacity of MTB is increased, it can sense nutrient and attract to the cancer site. The use of MTB with our hypothesis will be the best strategy to treat cancer disease. MTB can be monitored externally with the help of magnetic field. The present review article summarizes the use of MTB as a therapeutic agent and comments on prevention of a cancer.
