Introduction
Patients should maintain good daily habits and a positive mindset, avoiding excessive fatigue and emotional fluctuations to prevent worsening of the condition. Pay attention to a healthy diet and avoid consuming excessive high-fat foods and beverages with high estrogen content. Regular follow-up examinations are an important task for patients with BI-RADS category 3 breast nodules, to promptly detect any possible malignant changes.
Generally, category 3 breast nodules are considered likely to be benign and are usually not serious, but regular observation is necessary. If the nodule's size and shape remain stable during follow-up examinations, surgery typically is unnecessary. However, if the category 3 breast nodule is large in size, surgical removal is usually required. Detailed analysis is as follows:
I. Is it serious?
The Breast Imaging Reporting and Data System (BI-RADS) classifies breast nodules into categories 0 to 6. Category 3 nodules have a high probability of being benign, with a risk of malignancy generally less than 2%. This indicates that most BI-RADS category 3 breast nodules are benign lesions, such as fibroadenomas or cysts.
It is recommended to undergo a breast ultrasound examination every 3 to 6 months to monitor any changes in the nodule's size, shape, margin, and internal echo characteristics. For older patients or those with nodules showing suspicious changes, additional mammography may be considered. Mammography can detect subtle calcifications or other lesions that may be missed by ultrasound alone, complementing ultrasound evaluation and providing a more comprehensive assessment of the nodule.
II. Is surgery necessary?
The risk of malignancy in BI-RADS category 3 breast nodules is generally less than 2%. If the nodule's characteristics, such as size, shape, margin, and internal echo, remain stable over multiple follow-up examinations and the physician's overall assessment indicates a very high likelihood of benignity, continued observation without surgery is usually appropriate. Common benign conditions like fibroadenomas often present as category 3 nodules and typically grow slowly with stable characteristics, making surgery unnecessary in such cases.
If a BI-RADS category 3 breast nodule is large enough to cause noticeable changes in breast appearance, such as localized breast protrusion, leading to psychological distress or affecting quality of life, surgical removal is generally recommended. Additionally, if the nodule causes breast pain or tenderness—especially if symptoms recur frequently—or compresses surrounding tissues causing discomfort, such as affecting arm movement, surgical excision may help alleviate these symptoms.
Patients should maintain healthy lifestyle habits and emotional well-being, avoiding excessive fatigue and emotional fluctuations, which may worsen the condition. Attention to a healthy diet is important, including avoiding excessive intake of high-fat foods and those containing high levels of estrogen. Regular follow-up examinations are crucial for patients with BI-RADS category 3 breast nodules to detect any potential malignant changes promptly.
