I am on nexxium 40mg after being diagnosed with non erosive reflux disease. Endoscopy was done 6 months ago and was normal except for some gastritis. I have recently (last week) started to see blood in my saliva esp in morning - usually rust coloured. Sometimes after eating something i spit and see blood that is fresh. ENT specialist has done endoscopy for nose and throad which was normal. I am 39 yo male. Never smoked or drank alcohol. Worried about esophageal cancer

Summarized question: Is esophageal cancer related with bloody saliva?
