My friend was diagnosed with stage 4 colon cancer.The lymph nodes in her neck were positive for cancer "likely" of the GI tract.The biopsy of the mass they found in her colon came back negative.Her MRI is clear but CT shows numerous nodes in her abdomen.Because the colon mass was negative,she is afraid she is getting the wrong chemo.The doc said because of what the nodal biopsy showed,the treatment regimen was correct Anyone have any ideas?We are working on a 2nd opinion.She is only 48.Thank-you
