How many grades is mammary gland hyperplasia classified into?

Benign breast hyperplasia poses significant health risks to women—not only causing various physical discomforts but also adversely affecting psychological well-being, often leading to irritability and mood instability. So, how many grades does benign breast hyperplasia have?

Grading of Benign Breast Hyperplasia

Benign breast hyperplasia is classified into six grades based on color Doppler ultrasound and mammography (molybdenum target imaging):
Grade 1: Negative—no abnormality detected.
Grade 2: Simple benign breast hyperplasia.
Grade 3: Benign lesions, such as fibroadenomas, cysts, or inflammatory changes.
Grades 4A, 4B, and 4C: Typically indicate fibroadenoma-like benign tumors, but with increasing risk of malignancy—5% for 4A, 50% for 4B, and 95% for 4C.
Grade 5: Indicates a 98% likelihood of breast cancer.
Grade 6: Confirmed diagnosis of breast cancer, established definitively by cytology and/or histopathology.

Modern life proceeds at a rapid pace, accompanied by considerable work- and lifestyle-related stress. Prolonged exposure to such stress may trigger adverse emotional states—including depression or anger—which, over time, can disrupt endocrine function and predispose individuals to benign breast hyperplasia. Therefore, learning to regulate one’s emotions and appropriately express or release them can help reduce the incidence of this condition.

Avoid chronic sleep deprivation; instead, maintain a healthy sleep schedule—going to bed early and rising early—to prevent endocrine imbalance induced by insufficient sleep, which may contribute to benign breast hyperplasia. We hope this information proves helpful!
