Breast cancer precursor

In breast cancer, we differentiate between real preliminary stages and so-called risk lesions. Real cancer precursors – so-called in situ carcinoma (DCIS), if left untreated, usually lead to real, invasive breast cancer and are therefore treated surgically like real breast cancer. Risk lesions, on the other hand, are "only" a sign of an increased risk of breast cancer.
 
All of these changes are hardly recognizable as a tactile finding, but are mostly discovered as the smallest microcalcifications with the chest X-ray, the mammography, as part of an early diagnosis examination. The diagnosis is confirmed by means of a large-volume tissue biopsy under X-ray view. Depending on the type of risk lesion, either a supplementary surgical procedure is necessary or further observation is sufficient.
 
State-organized mammography screening is used across the board in the vast majority of countries in order to discover real cancer precursors or risk lesions in good time.
