[|Human|] I have episodes (sporadically) of waking up around 4 or 5 in the morning with a knife-like pain in upper stomach and throat. May be acid reflux. Im taking Nexion and have also had one of those episodes while on the medication. Could I have esophogeal cancer? My calcium blood level - for the first time - read at 11.3 (mild abnormality) and Im repeating the test this week while fasting. I am very worried though my doctor said lets take one step at a time.
[|AI|]  HelloWelcome to Chat Doctor It is very difficult to tell you what is causing you pain from your symptoms. It is more likely due to HERD or gastritis rather than cancer. Tobacco and alcohol use are considered the major risk factors in the development of esophageal cancer. Other causes are obesity, H pylori infection, HERD etc. You need to undergo upper GI endoscopy for your medical condition be it HERD or gastritis. Fortunately endoscopy is also investigation for esophageal cancer, and it can tell you whether you have cancer or not. Regards
