Introduction
Excessive mental stress, intense emotional fluctuations, and other adverse psychological factors may impede the normal regression—or result in incomplete regression—of benign breast hyperplastic tissue. Over time, this can lead to persistent breast hyperplasia. Moreover, such adverse psychological stimuli can exacerbate existing symptoms of breast hyperplasia.
Mastopathy (benign breast hyperplasia) is the most common breast disorder among women, ranking first in incidence among all breast diseases. In recent years, its prevalence has been rising annually, and the age of onset has been decreasing. Most cases involve benign breast hyperplasia; however, a small proportion of patients may experience malignant transformation. One such precancerous condition is fibrocystic breast disease—thus, vigilance remains essential.
Etiology and Classification of Mastopathy
Adverse psychological factors—such as excessive mental stress or intense emotional agitation—may impede the normal regression of hyperplastic breast tissue, leading to persistent or incomplete resolution. Over time, this contributes to the development of mastopathy. Moreover, such psychological stressors can exacerbate existing symptoms.
Multiple induced abortions increase the risk of developing mastopathy.
Imbalance in sex hormones—specifically, absolute or relative elevation of estrogen coupled with absolute or relative reduction of progesterone—disrupts normal breast architecture.
Long-term use of estrogen-containing health supplements or oral contraceptives may also trigger mastopathy.
Classification
Mastopathy encompasses several subtypes. Some are entirely physiological and resolve spontaneously without specific intervention—for example, simple mastopathy. Others are pathological and require active treatment, especially cystic mastopathy, which carries a risk of malignant transformation and therefore warrants careful attention.
Mastodynia (Breast Pain Syndrome)
Also known as simple mastopathy, this condition is most prevalent among adolescents and young women. It results from heightened and fluctuating gonadal hormone secretion. Its hallmark is distinct cyclical breast tenderness, which typically resolves spontaneously after menstruation. Pain is primarily localized to the breasts but may radiate to the ipsilateral axilla or chest wall. This type represents a normal physiological phenomenon; patients need not panic or become overly anxious. With appropriate emotional regulation and maintenance of hormonal balance, elevated endocrine hormone levels usually normalize gradually, and associated symptoms often resolve spontaneously.
Mammary Gland Disease (Mammopathy)
The underlying pathology involves both ductal and lobular dilation within the breast, accompanied by proliferation of periglandular connective tissue.
Cystic Mastopathy
This subtype is characterized primarily by epithelial hyperplasia of the mammary ducts. Palpable breast masses typically present as diffuse thickening; some patients exhibit localized lesions, most commonly oval-shaped cystic structures that may be easily confused with fibroadenomas. Due to its potential for malignant transformation, cystic mastopathy frequently causes patient anxiety and distress.
