Common Types: Luminal Type, Luminal B (HER-2 negative), Luminal B (HER2 positive), HER2 positive, three negative

Targeting treatment: First consider surgical treatment and endocrine therapy, the whole body treatment recommendation scheme is as follows:

Luminal A	Most patients only need endocrine treatment
Luminal B（HER-2 Negative）	All patients need endocrine treatment, most patients need to chemotherapy
Luminal B（HER-2 Positive）	HER2 targeted drug + chemotherapy + endocrine treatment
HER-2 Positive（non-Luminal）	HER2 targeting drug + chemotherapy
Three negative	Chemotherapy, PARP1 inhibitors are in clinical experiments

Pathogenic factors: hormone level, benign breast disease, BRCA1 / BRCA2 gene mutation, etc.

High-risk population: BRCA1 / BrCA2 gene mutant carrier, family genetic history.

Early screening: Early multidamine molybdenum target examination and combined B-ultrasound and clinical medical examination are not recommended for non-high-risk populations under 40 years old.
