Mulheres brasileiras devem começar o rastreamento de câncer de mama aos 50 anos — não aos 40, como recomendam os Estados Unidos desde abril de 2024. O Instituto Nacional de Câncer (INCA) reafirmou em janeiro de 2025 sua diretriz de mamografia a cada dois anos para a faixa dos 50 aos 69 anos, mesmo após revisar as novas orientações americanas.
Mammography is an exam that allows identification of breast lesions and acts as preventive care for breast cancer, recommended annually after age 40 by some specialists. The exam ensures simple treatment with better chances of cure and less impact on women's quality of life when changes are detected early.
Brazilian press articles recommend annual mammography starting at age 40, contrasting with official INCA guidelines
