Patient's question:
In 2011, a small hard lump was found in the left breast and later treated at a rehabilitation hospital.Doctor's answer:
The causes of breast cystic hyperplasia are many, but they are primarily closely related to endocrine disorders or emotional and mental states. Hair dyeing and perming can cause endocrine disorders, so it is best not to dye or perm hair, maintain a relaxed mood, and take medication on time.
