Tim,

Of course Brian will have the ultimate answer, but my understanding is that we are at a higher risk for a second primary cancer, especially in the aerodigestive tract, because we have had head and neck SCC. Therefore, I have had endoscopy with biopsies to check for Barrett's esophagus and I take Nexium to prevent the whole situation from happening because I do sometimes get heartburn if I don't take the medication. I'd rather be safe than sorry. The endoscopy will be repeated every 3 years.
