"At what mm size should a breast nodule require surgery?"

Surgical Necessity of Breast Nodules

The decision on whether or not to perform surgery for breast nodules is not solely based on their size. Rather, it necessitates a comprehensive evaluation by medical professionals, taking into account specific factors such as the nodule's size, shape, edge characteristics, and any indications of malignancy. Adherence to a doctor's professional guidance for appropriate examination and treatment is crucial. Typically, breast nodules smaller than 5mm have a lower likelihood of malignancy, and physicians may recommend regular monitoring rather than immediate surgery. However, if a nodule rapidly increases in size during monitoring or exhibits other signs of malignancy, surgical removal may be considered to obtain a pathological diagnosis and determine its nature.

For nodules larger than 5mm, physicians will conduct a more cautious assessment, which may include imaging examinations and biopsy to evaluate the nature of the nodule. If imaging suggests malignant features or if the biopsy results are inconclusive, surgical intervention may be advised. According to Dr. Wang Yu, an associate chief physician and Ph.D. from Beijing Tongren Hospital, as stated in potentially helpful reference information, the size of a nodule is just one factor to consider. When a breast examination report mentions low echogenicity, irregular morphology, or visible blood flow in a nodule, it often indicates a potential malignancy, necessitating prompt medical attention for further assessment.

In daily life, maintaining a healthy diet, avoiding obesity, reducing exposure to hormones, and engaging in regular physical activity can all contribute to reducing the risk of breast diseases.
