Cancer is still one of the biggest health challenges worldwide. Traditional treatments like surgery, chemotherapy, and radiotherapy save many lives, but they often cause serious side effects and sometimes fail because the drugs cannot target cancer cells. This is where nanotechnology is making a big difference. By using extremely small particles called nanoparticles, scientists can design treatments that carry medicines directly to tumors, release them in a controlled way, and spare healthy tissues from unnecessary damage. Different types of nanoparticles, such as liposomes, dendrimers, and metallic or carbon-based materials, are being explored for delivering chemotherapy drugs. These particles can naturally build up in tumor areas due to the leaky blood vessels around cancers. They can also be specially designed to recognise cancer cells by attaching targeting molecules like antibodies. Nanotechnology is also opening doors for “theranostics,” where therapy and diagnostics are combined in one system, allowing doctors to treat cancer while also tracking how well the treatment is working. Some nano-based medicines, like Doxil and Abraxane, are already approved and in clinical use, showing that this technology is not just experimental but practical. Still, challenges such as largescale production, safety testing, immune reactions, and regulatory approvals need to be solved before nanotechnology can reach its full potential. Overall, nanomedicine holds the promise of making cancer treatment more precise and effective.
