The high likelihood of a metastatic tumor from bowel cancer means that the tumor may have formed as a result of metastasis from bowel cancer. Bowel cancer is a common malignant tumor, including colon cancer and rectal cancer. Bowel cancer can be metastasized or implanted to other parts of the body through the occurrence of lymphatic metastasis, bloodstream dissemination and direct spread. Manifested as tumor of extraintestinal organs, resected tumor tissues sent for examination can see pathological manifestations of intestinal cancer tissues. The high possibility of intestinal cancer metastasis indicates that the tumor may be formed by intestinal cancer metastasis. At this time, combining with immunohistochemistry results or resecting more tissues for pathological examination can further clarify the diagnosis. If the metastasis of bowel cancer has been clarified, it indicates that the tumor has already reached the advanced stage and the prognosis is generally poor. If metastasis of intestinal cancer occurs, one should go to the hospital in time and have specialized treatment under the guidance of doctors.
