I am 84 years old and have just turned down surgery. After radiation and chemo, no cancer was seen in the PET scan and was not found after a scope with biopsies. The scope really confirmed my decision to just wait and watch. The surgery would have given me about a 60% chance to not die of esophageal cancer for 5 years. but some say it takes a year to recover from the surgery. I choose to not give that year up, and to hope I will live a few more good years, perhaps dying of something else.
You, the patient have to decide. It's hard, but you have to choose. Gather the best information you can, first, then decide. there is no easy way to do this.
