Close exam: primary tumor cells are well defined, arising in the organ that initiates the lesion. A cancer of the breast when biopsied shows adenoca cells of breast origin. When metastatic to liver or lung, biopsy will show the same cells as the primary . If the lesion arises in the liver it is not metastatic in terms of cells seen but liver tumor cells or hepatoma.
