Breast cancer is a leading cause of death among women in Tanzania, necessitating effective early detection programmes. A mixed-methods approach was employed, including surveys, focus group discussions, and qualitative interviews with CHWs and participants. Community health workers demonstrated a 75% success rate in identifying potential cases of breast cancer during routine check-ups. CHWs play a crucial role in early detection but require additional training and resources to enhance their effectiveness. Enhanced training programmes should be implemented, along with improved referral mechanisms for further diagnostics. Community Health Workers, Breast Cancer Early Detection, Tanzania
