Invasive cancer: malignant cells have penetrated into the surrouding cells and are at risk for metastases.
In situ (dcis) is a condition where malignant appearing cells do not have that penetration - and have little or no risk of metastases. Invasive breast cancer requires lumpectomy (with radiation) or mastectomy. Most patients receive some sort of whole body treatment: chemo or hormonal block.
