<s>[INST] 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 [/INST] Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about esophageal cancer. Since you are not smoker or not taking alcohol and having age less than 50 years, possibility of esophageal cancer is very, very less. Possibility of bleeding from stomach ulcer is more. You are having gastritis. So if this is worsened than it can cause bleeding. So better to get done repeat upper GIs copy to rule out this. Also get done chest x-ray to rule out lung related causes because this can also cause blood in saliva. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
