Introduction
BI-RADS category 4A in the right breast indicates a low suspicion of malignancy. This classification means that the lesion present in the patient's right breast has a 90%–98% likelihood of being benign and a 2%–10% likelihood of being malignant. Therefore, BI-RADS category 4A in the right breast refers to a lesion with low malignant potential.
BI-RADS category 4A in the right breast indicates a low suspicion of malignancy.
BI-RADS category 4A in the right breast means that the patient has a lesion in the right breast, with a probability of benignity ranging from 90% to 98% and a probability of malignancy from 2% to 10%. Therefore, BI-RADS category 4A in the right breast is considered to represent a low risk of malignancy. To determine the exact nature of the lesion, further examinations are required. Benign lesions in the right breast typically have well-defined margins, whereas malignant lesions usually present with unclear or irregular margins. Thus, imaging tests such as breast ultrasound or CT scans can be used for diagnosis. Alternatively, a pathological biopsy can accurately determine the nature of the lesion, although this method may require a local puncture to obtain tissue samples.
It is recommended that after confirmation of the right breast lesion, patients receive targeted treatment based on their individual conditions. During treatment, strenuous physical activities should be avoided.
