Breast cancer: Why is early screening essential?

Breast cancer may cause no visible symptoms in its early stages, and late detection can make treatment more complex. Early screening can identify abnormalities before symptoms appear, improve the chances of successful treatment and often allow less intensive care. A lump in the breast or under the arm, changes in breast shape or skin, persistent discomfort, or unusual nipple discharge warrant medical advice. Mammography is a key screening test; a health professional may also recommend a clinical examination, ultrasound, or other tests based on age, family history, and risk factors.
