Functional Assessment of Cancer Therapy - Breast (FACT-B) questionnaire.

Change in health-related quality of life (HRQoL) from baseline to 12 weeks, assessed using the Functional Assessment of Cancer Therapy - Breast (FACT-B) questionnaire. The FACT-B is a validated, self-administered instrument that evaluates five domains: physical well-being, social/family well-being, emotional well-being, functional well-being, and breast cancer-specific concerns. Scores for each domain and the total FACT-B score were calculated according to standardized scoring guidelines, with higher scores indicating better quality of life. Participants completed the questionnaire at baseline (pre-intervention) and at 12 weeks (post-intervention)
