The emerging scientific field of Nanotechnology enabled humanity to manipulate the environment at molecular and atomic level and it promises to revolutionize all scientific fields due to its features. Medicine is one of the prominent fields that witnessed a nanotechnological revolution that ushered medical scientists toward wholly new authentic approaches which study pathologies and explore genuine therapeutic stratagems by utilization of nanotechnology to operate on more specific molecular targets and to reduce the adverse risks and side effects that conventional approaches impose on patients. To take a better view on the impact of nanotechnology on medicine. The ramification of this technology shall be explored in terms of medical outcomes. It will reduce societal and financial expenses related with human services, offer early location of pathologic conditions, decrease the seriousness of treatment, and result in enhanced clinical result for the patient. The most promising treatment for cancer is nanotechnology that can be used in treatment and detection. The current treatments for cancer is ineffective with high chances of tumors to grow again and resistant to the treatment which makes it worse in addition to the severe adverse effect of the current treatments. The early detection of cancer can elevate the chances of curing and prevent recurrence, however the technologies and methods used in detection is limited and ineffective which worsens the condition. Intracellular drug delivery and photothermal ablation are promising treatment for cancer. Prostate cancer affects over 2.5 million Americans, but there is an unmet need for targeted treatment with minimal systemic toxicity, especially for metastatic disease. Prostate cancer tumors are characterized by a mixed cell population which is hard to target one treatment for different kind of cells.
