Human knowledge, with all its growth and development, is still in its initial stages of finding efficient ways to treat cancer. The elevated number of cancer patients puts cancer treatment amongst the top priority of scientific research facilities. The advent of nanotechnology opens new windows that promise effective ways in locating the chemical sources, tracking them, controlling the cancerous cells, and finally terminating them.

Cancer is the unusual and uncontrolled growth of cells that have the ability to migrate to other locations and spread out. Cancerous cells replicate faster than healthy cells, causing strain in the nutrient supply and in the elimination of metabolic waste products. Due to the fast growth of the cancer cells, the healthy cells cannot compete for adequate nutrients, and will eventually be replaced by tumor cells. After a tumor develops, only the c...read more
