Biopsy: "sigmoid colon, well differentiated adenocarcinoma, grade i" does this indicate that the tumor won't probably metastasize? triphasic ct shows a lesion in the liver (1cm) as well.

Grade 1 is a good: Sign, but nothing is guaranteed. Need to further understand the liver lesion as well. Work with the medical team to put together the best treatment plan for the individual patient situation.

Imaging consult: Is a good idea. Your ct scan can be submitted to http://conciergeradiologist.Com in the next few weeks for reevaluation. One picture is not enough - the whole study will need to be sent, but fortunately that's not hard. Having an expert radiologist review your scan and pointing out results to you clearly can clarify whether that lesion is a metastasis or a benign hemangioma (or something else).

Depends on Pathology: When you say grade one, i assume you mean stage 1, which is good. Stage 1 has a very high chance of being cured with surgery alone but the chance of spread to the liver is not zero. So your multidisciplinary team should evaluate your pathology and the appearance of the liver lesion to determine its clinical significance and if additional therapy is necessary. If grade 1, more info is needed.
