Invasive cancer means the cancer cells have broken out of the lobule where they began and have the potential to spread to the lymph nodes and other areas of the body. In the same manner as the granulations may produce a racemose appearance of the hepatic surface, they may, when several of them are grouped together, produce larger protuberances, or lobes; if the interstitial cellular tissue is much condensed, the peripheral groups may become pediculated, so as to resemble mere appendices. Lesions with a round or oval shape are always suspicious for metastasis. Stick to this routine in the beginning, even if it seems somewhat tedious. Scanning across the liver in longitudinal sections.
