Cystic hyperplasia of breast

This disease is one of the common and frequently-occurring diseases in women. It is more common in women aged 25 to 45. It is essentially a disorder of the normal structure of the breast caused by physiological hyperplasia and incomplete restoration. In China, cystic changes are rare and mostly glandular hyperplasia, so it is often called "breast hyperplasia". The World Health Organization (WHO) collectively refers to "benign malformations of the breast". The risk of malignant transformation of this disease is 2 to 4 times higher than that of normal women. Clinical symptoms and signs are sometimes mixed with breast cancer.
