Nanotechnology a Boon for Colorectal Cancer Treatment

Background: Colorectal cancer (CRC) is the third most widely spread tumor among the human population. It is usually adenocarcinomatous and develops as a polyp on the inner wall of the colon or rectum which may become malignant with time. Though its treatment is limited, its early diagnosis and prevention play a better role, thereby decreasing mortality rates. Objective: The molecular markers in CRC-affected tissues may play an important role to develop novel strategies to cure the disease. Nanotechnology consists of both an innovative diagnostic and therapeutic array of nanomaterials that may be used to target CRC like dendrimers, carbon nanotubes, nanoparticles, nano-emulsions, etc. Methods: Current patents and research covering the nanotechnology used to target and diagnose CRC is included in the review. Results: Nanotechnology is playing a wonderful role in both the treatment and diagnosis of CRC. Conclusion: The present review may cover the recent advancements in nanotechnology in the treatment and diagnosis of CRC.
