When cancer occurs in the breast, it will be categorized based on whether it is invasive or noninvasive; these categories are further broken down into different types. For example, the most common type of invasive breast cancer is infiltrating ductal carcinoma. Invasive refers to disease that has spread, whereas noninvasive refers to disease that has not yet spread.
Tools and tests used to diagnose cancer of the breast include:
- Mammogram
- Ultrasound
- Magnetic resonance imaging (MRI)
- Biopsy
- Fine-needle aspiration.
Once a diagnosis has been confirmed and the stage has been determined, treatment for breast cancer will begin.
