- Breast cancer survivors in a Korean cohort study showed an 8% lower risk of Alzheimer's disease.
- Among treatment modalities, only radiation therapy was significantly associated with reduced Alzheimer's disease risk.
- The study addressed limitations of prior research by incorporating competing risk analysis and adjusting for various potential confounders.
- The researchers proposed biological explanations for the observed associations.
- The study concluded that breast cancer treatment does not directly lead to Alzheimer's disease.
- Clinical implications highlight the reassurance about the cognitive safety of breast cancer treatment in relation to Alzheimer's disease.
