A nurse is caring for a client who has a family history of breast cancer. Which of the following should the nurse include when discussing secondary prevention of breast cancer?

A. Secondary prevention focuses on early detection and screening of disease to prevent progression and improve outcomes. An annual mammogram helps detect breast cancer at an early stage when treatment is most effective, making it a key example of secondary prevention. B. Maintaining a healthy BMI is a primary prevention strategy. It reduces the overall risk of developing breast cancer and other chronic diseases but does not involve screening or early detection of an existing condition. C. A prophylactic mastectomy is a tertiary prevention or risk-reduction intervention for individuals at very high risk (such as BRCA mutation carriers). While it reduces the chance of developing breast cancer, it is considered a treatment or risk-reduction strategy rather than routine secondary prevention.
