Breast cancer can recur if undetected cancer cells remain in the body after treatment or spread to other areas. Recurrence may occur locally in the breast, in nearby lymph nodes, or as distant metastasis. Factors influencing recurrence include the cancer type, tumor size, grade, and effectiveness of initial treatment. After treatment, it’s crucial to attend regular follow-up appointments, maintain a healthy lifestyle through exercise, balanced diet, and weight management, and manage mental health. Adhering to prescribed treatments like hormone therapy is essential. Regular self-examinations and staying vigilant for changes also play a key role in detecting recurrence early.
