This brief provides an insight into the present scenario of the role of
nanotechnology in the diagnosis and treatment of lung cancer at an early
stage. Currently, lung cancer is the subject of major concern owing to
the very high mortality rate throughout the world. Most of the
conventional treatment methods such as surgery, chemotherapy,
radiotherapy, etc., fail to prolong life of the patients. Incidents of
recurrence are also very common in case of lung cancer. Researchers have
shown that nanoparticles may act as a powerful anti cancer tool,
especially for lung cancer. Unique surface properties and easy surface
functionalization of nanoparticles enable early detection, diagnosis,
imaging and treatment of lung cancer. The authors have elaborately
presented how various nanoparticles (natural, semi synthetic and
synthetic) may help in the treatment of lung cancer. They have also
detailed works of various scientists who succeeded in developing
effective nanoparticles and enabled very specific lung cancer therapy
without any undesirable side effects and minimized death.
