<s>[INST] My husband has stage 4 esophageal cancer that has spread threw his entire body except his brain what should we look for [/INST] Hi well come to Chat Doctor. Since stage 4 with spread in other parts of body, only treatment left out is chemo therapy. Radiation to particular part will not help, and even surgery at so many areas is not possible.  Best thing is chemo therapy with maximum symptomatic treatment and comfort to him is more important for what ever life is left out. Should not hesitate to use even addictive Chat Doctor.  Thanks </s>
