ABSTRACT
Cancer is a communal health issue with a yearly increase in fatality rates and the world’s largest cause of mortality. Most of the cancers in the world are due to several behavioral and environmental risks that are potentially compliant. Cancer is accountable for up to 1.5 million cancer deaths a year. Until now, scientists have made attempts to develop a variety of chemoprevention and treatment methods, including surgery, chemotherapy, and radiotherapy, but more research is still needed to discover novel approaches to cancer treatment. This chapter outlines current achievements in nano-formulation-based chemoprevention techniques for various forms of cancer. Nanotechnology has yielded numerous promising discoveries, including drug delivery. Antitumor medications and biomolecules, like antibodies peptides, and many additional compounds, can be joined with nanoparticles to recognize highly specific tumors; those are important in cancer cell diagnosis and screening. Nano-formulations contain particles smaller than 100 nm, and the medicine is dissolved, entrapped, encapsulated, or linked to the drug carriers. Because of their nano size, wide surface area, the inclusion of both hydrophilic and lipophilic elements, long circulation period, and multifunctionality, these drug carriers have outstanding qualities in terms of absorption, targeting, and safety.
