I’m 28 months into my esophageal cancer I’ve had chemo radiation And currently I’m in immunotherapy every three weeks. i’ve had the hiccups since before I was diagnosed every time I would eat something that was firm. I would hiccup until I threw up. It’s much better now I watch what I eat. i’ve had five clean CAT scans. My next one is October 7. Doctor says if I get that clean he will stop treatment.
