According to ICD-10-GM, the following forms of mastopathy can be distinguished:
- ICD-10-GM N60.0 – Solitary cyst of the mamma.
- ICD-10-GM N60.1 – Diffuse cystic mastopathy.
- ICD-10-GM N60.2 – Fibroadenosis of the mamma
- ICD-10-GM N60.3 – Fibrosclerosis of the mamma
- ICD-10-GM N60.4 – Ectasia of the ductus lactiferi
- ICD-10-GM N60.8 – Other benign mammary dysplasia.
* Cysts – cysts (fluid-filled cavities) arise from dilated milk ducts and glandular lobules (lobules). * * Fibrosis – in fibrosis, the change in mammary tissue is primarily in the connective tissue.
Adenosis – in adenosis, there is an imbalance between connective tissue and glandular tissue, with a marked increase in glandular parenchyma.
Mastopathy often occurs on both sides and is the most common disease of the breast in women.
Peak incidence: the maximum incidence of mastopathy is between the ages of 30 and 50.
The prevalence (disease frequency) is up to 60% of women (in Germany).
Course and prognosis: In mild forms of mastopathy, the main focus is on treating premenstrual pain (occurs up to two weeks before menstruation). If the mastopathy is accompanied by lump formation, it must be surgically removed and examined histologically (by fine tissue).
