Stage IIIB describes invasive breast cancer in which:
- the tumor may be any size and has spread to the chest wall and/or skin of the breast AND
- may have spread to axillary lymph nodes that are clumped together or sticking to other structures, or cancer may have spread to lymph nodes near the breastbone
- Inflammatory breast cancer is considered at least IIIB
Stage IV
Stage IV describes invasive breast cancer in which:
- the cancer has spread to other organs of the body -- usually the lungs, liver, bone, or brain
"Metastatic at presentation" means that the breast cancer has spread beyond the breast and nearby lymph nodes, even though this is the first diagnosis of breast cancer. The reason for this is that the primary breast cancer was not found when it was only inside the breast. Metastatic cancer is considered stage IV.
Roxanne, above is described the difference between the two....and in our TNBC - every stage is treated aggressively!
