Here's a quixotic twist: It appears that battling certain types cancer may lower the risk for developing Alzheimer's disease, new research suggests. After pouring over data, investigators have concluded that most kinds of cancer - with the exception of prostate cancer - seem to confer some degree of protection against Alzheimer's, reducing risk of the age-related brain disorder by anywhere from 9% to 51%. They've also linked a common form of cancer treatment, chemotherapy, to a lower risk for developing Alzheimer's-related dementia.
