May I ask if you or any others who have had esophageal cancer had a lot of mucus and saliva BEFORE treatment? My sister quite possibly has it(either Stage 4 cervical cancer mets or a primary) and she gets choked and coughs with lots of mucus and saliva about every other day. No blood in it but LOTS of it. My understanding is it can go on for several hours and then seem normal. She has a lot of gas, as well as getting hiccups. No taste to the mucus-just clear. Thanks so much! God bless!
