Nanotechnology Tackles Brain Cancer

Brain cancer can be counted among the most deadly and intractable diseases. Often diagnosed after a patient exhibits symptoms such as nausea, dizziness, uncharacteristic behavior changes, or paralysis, the growing mass of a brain tumor will continue to squeeze out normal tissue and degrade the brain's function if left untreated. But treatment is elusive. Tumors may be embedded in regions of the brain that are critical to orchestrating the body's vital functions, while they shed cells to invade other parts of the brain, forming more tumors too small to detect using conventional imaging techniques. Brain cancer's location and ability to spread quickly makes treatment with surgery or radiation like fighting an enemy hiding out among minefields and caves, and explains why the term "Brain Cancer” is all too often associated with the word” Inoperable."
