Nanotechnology and Bioinformatics: The Fight for Cancer IntroductionCancer is a very complex disease caused by damage to the genes that control the growth and separation of cells. The instructions that tell cells to function come from genes. In order for cancer cells to grow, they need blood. A molecule that looks like or works like a hormone causes nearby blood vessels to grow toward the cell to supply oxygen and other nutrients. To cure cancer, the damaging mechanism must be corrected, or the blood supply to the cells must be cut off, or the cancer must be destroyed. Current prognostic and diagnostic classifications fail to reflect the clinical heterogeneity of tumors and are inadequate in making predictions for treatment success and patient outcomes. Some current anticancer agents do not show the difference between normal and cancerous cells, this creates adverse effects and systemic toxicity. Many times cancer is diagnosed in its late stages and treated late, by which time the cancer has invaded and penetrated other parts of the body. Bioinformatics is the application of computer technology that manages biological information. Computers are used to collect, store, integrate, and analyze biological and genetic information that can be used in gene-based drug development and discovery. Bioinformatics capabilities have been accelerated by the explosion of publicly available genomic data resulting from the Human Genome Project. Nanotechnology is a field in which many different types of devices have been developed from physics, engineering, chemistry, and biology. For the targeted delivery of anticancer drugs and...... half of the paper ......m information on transcription factor binding has been applied, for the interaction between the response to anticancer therapy and the molecular state of the cell. Multivariate testing has been used to help clinicians understand the application of PAM50 centriodic-based genomic predictions for breast cancer. This process characterizes an error introduced into test results by inherent error in sample preparation and factor measurement. which helped .ConclusionNanotechnology and bioinformatics play a very important role in cancer treatment. There is still a need for new applications to help people around the world. These new applications must be more advanced than those available and must not cause harm to humans. It is very important to diagnose cancer at an early stage, this could prevent many people from dying. Bibliography
