Hi! Good evening. I am Dr Shareef answering your query. Performing a biopsy does not necessarily mean that the ulcer would be cancerous. We have to wait for the report to have any confirmation. The ulcers or swelling could also be some kind of benign lesion. Till the reports come in, I would advise your friend to have a proton pump inhibitor drug for a symptomatic relief. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
