Hello, Generally seen in the younger child bearing age, this fibroadenosis or fibrocystic breast disease is due to the cyclical changes that occur in the hormones. It is mostly benign and can be treated with simple techniques like analgesics, firm breast support and diuretics. Mammogram and ultrasound may be done to exclude a lesion. In one subtype, known as atypical ductal or lobular hyperplasia, there is a four-fold increased risk of malignancy than the normal population and this risk is doubled if there is a positive family history. Hence, careful follow up is needed in such a situation. Fine needle aspiration helps to know the cytology. Hope this helps.
