What is the meaning of bilateral breast cystic nodule 2?

The BI-RADS

is a breast image reporting and data system for assessing the benign and malignant extent of breast lesions. Grade 2 indicates benign hyperplasia rather than malignant lesions. Because breast cystic nodules are benign

lesions, special treatment is usually not required, but regular follow-up is recommended to monitor the changes of nodules. It is generally recommended to visit the hospital every 3-6 months for breast ultrasound examination.
