Grade 3 breast enlargement is generally defined as grade 3 on the BI-RADS imaging scale, which is often difficult to recover from on its own and requires intervention through medication. Most cases of Grade 3 breast enlargement are benign, with a 97% or greater likelihood of benign breast disease and less than a 3% likelihood of malignancy in this classification. Patients with Grade 3 breast enlargement can improve the condition by modifying their own behavior, such as eating a low-fat, low-sugar diet, avoiding spicy and stimulating diets, avoiding excessive intake of hormone-containing foods, exercising moderately, getting enough rest and sleep, not staying up too late, etc. If the above methods are not effective, it is important to take them into consideration. If the above methods are not effective, it is recommended to use Chinese medicines such as Breast Fetish Elimination and Anti-inflammatory Pill under doctor’s guidance to ease the liver, activate blood circulation and remove blood stasis, together with regulating one’s own behaviors, which can generally control Grade 3 breast hyperplasia. It is recommended that patients with Grade 3 breast hyperplasia should consult a doctor in a timely manner and undergo standardized treatment after completing relevant examinations.
