Striated hyperplasia is a type of breast hyperplasia, which belongs to benign lesions of the breast and is related to endocrine disorders, improper dietary habits, mental factors and wearing improper bras. 1. Endocrine disorders: especially related to the rise of estrogen level in the body, estrogen stimulates the breast ducts and breast tissue, causing hyperplasia, which can be in the form of cords. 2. Improper diet and living habits: such as staying up late, smoking, drinking alcohol, etc., can lead to the rise of estrogen in the body, followed by breast hyperplasia. 3. Mental factors: long-term depression, anxiety and mental stress can lead to endocrine disorders. 4. Improper bras: wearing improper bras for a long time, especially too tight bras, can cause pressure on the breasts, affecting the blood supply, and then induce the disease. Patients with breast hyperplasia should improve the above improper habits, and if necessary, be treated by a professional physician for their condition.
