Input: Question: Does risk of subsequent dementia diagnoses vary by types of adjuvant chemotherapy in older women with breast cancer?
Answer: No association was found between types of adjuvant chemotherapy agents for breast cancer and risk of new dementia diagnoses. Our findings suggest that concerns about post-chemotherapy dementia should not be a major factor in determining type of adjuvant chemotherapy regimen to prescribe for older women with breast cancer.
Output:
no
