Symptoms

Types
- Invasive ductal carcinoma (most common)
- Invasive lobular carcinoma
- Hormone-receptor-positive, HER2-positive, and triple-negative subtypes
Diagnosis
Found by mammogram, ultrasound, and biopsy.
Treatment
Depends on type and stage: surgery, radiation, chemotherapy, hormone therapy, and targeted therapy, often in combination.
