A study in late November of 2020 found a weak inverse association between Alzheimer's Disease (AD) and cancer. Increased hospital surveillance and constant exposure to cytotoxins would theoretically correlate those with cancer history as having an increased chance of receiving an AD diagnosis. However, a superficial analysis of the data concluded that on average 35% of cancer survivors had a decreased risk of AD than those with no cancer history. Though, further evaluation of the data found that faulty diagnostic errors and study biases may contribute to AD symptoms being overlooked during a cancer patient’s diagnosis, as a revised calculation found that 11% expressed a decreased risk of developing AD in the future. This insight into the relation between AD and cancer may provide further information about their etiology.
