About The Study: This cohort study of breast cancer survivors found a lower risk of Alzheimer dementia (AD) compared with cancer-free controls, despite common concerns about cognitive decline after treatment. The findings suggest certain cancer treatments potentially have benefits for lower AD risk. Further research is needed to assess the long-term risk of AD in this population.
