Nanotechnology, the creation and utilization of materials, devices and systems through the control of matter on the nanometer has been applied to molecular diagnostics. Cancer is caused by damage of genes which control the growth and division of cells. Detection, diagnosis and treatment are possible by confirming the cancerous growth in the cells, rectifying the mechanism that is responsible for the damage caused in the genes and by interfering with the blood supply to these cells or by destroying them. Cancer is the leading cause of death in the World among all populations across different age groups. For the first time cancer has surpassed heart disease as in the number of deaths reported due to the disease. This worrisome statistic has resulted not from an increase in the incidence of cancer, but because deaths from heart disease have dropped nearly to half. It is a matter of deep concern to the world in general and scientific community in particular that the number of cancer-related deaths has remained about the same in the last decade. This fact accentuates the need for a new generation of more effective therapies for cancer and their successful launch in the world market. In this review, the details of newer treatment methods using nanotechnology are discussed.
