###Human: Why is there a tiny nodule in cardia? ###Assistant: Hi. I have gone through your query in detail. The endoscopy has shown a healing ulcer and is showing healing as well as a small hiatus hernia. There is a very tiny nodule in cardia (proximal part of the stomach), which has been biopsied. These tiny nodules are usually innocuous, but as a routine approach, it is biopsied to rule out any kind of early changes, if any. The report is very clear that they have not found anything sinister (please read it as cancer). I am almost certain that the biopsy is going to come out as benign. Please continue with PPI and wait for the biopsy. Once you have the biopsy and have any further concerns, you could always get back in touch.
