<s>[INST] Hi Doctor, my boyfriend had a gastroscopy performed last week. His physician called today to tell him that an amount WBCs were found in the sample that he took. He told him to continue to take his Protonix for the next 4 weeks and then they will do another gastroscopy. My boyfriend is only 27 and his father died from brain cancer 14 years ago. Should we be concerned that this could be some preemptive sign of cancer? [/INST] Hi and welcome to Chat Doctor. Thanks for the query. Stomach cancer is extremely rare in this age and this is the last thing to think of. WBC in sample isn't indicating anything malignant. It is indicating inflammation of stomach mucosa which is seen in gastritis, verb or h.pylori infection. So you should not be worried at all. He should continue with antacid medicines and change his dietary habits. Wish you good health. Regards </s>
