The investigators aim to use this information to further refine and evaluate a decision aid to help newly-diagnosed women aged 70 and older with breast cancer understand the risks and benefits of different types of breast cancer treatment. The Decision Aid (DA) was created for women 70 years or older diagnosed with ER+, HER2-, clinically LN-, 3cm or less breast cancers deciding on breast cancer treatment. The DA was designed considering the health literary, cognitive abilities, treatment outcomes, and competing health issues of older women.
