Alzheimer's may prevent brain cancers

For all the damage Alzheimers does, researchers believe the brain-debilitating disease may prevent its sufferers from developing brain cancer. "We believe that the small protein that causes Alzheimer's Disease, called amyloid, stops cancer blood vessels growing and thus the supply of nutrients and oxygen to the cancer is stifled," says Dr. Daniel Paris, lead author on the paper, in a release. Paris and other researchers found that mice that naturally developed Alzheimer's did not develop brain cancer as rapidly as those without Alzheimer's, due to the cancer's need for a larger blood supply than Alzheimer's will allow.
