Improvement of Cancer Therapy by Nanotechnology

Conventional cancer therapy has many drawbacks because of the high drug dose, systemic toxicity and lacking potential targeting output. The applications of nanotechnology for cancer therapy have been shown to overcome the limitation associated with conventional treatments. It plays a pivotal role by delivering cancer drugs in a sustained and targeted manner to the malignant tumour cells, thereby reducing the systemic toxicity of the anticancer drugs. It offers a unique approach and comprehensive technology against cancer therapy through early diagnosis, prediction, prevention, personalized therapy and medicine. This review discussed the various tools of cancer nanotechnology that are presently used in the improvement of cancer therapy.
