There is a new poll that we have just set up about heartburn. We did have one about Barrett's Oesophagus earlier that did show a large proportion of people who had oesophageal adenocarcinoma (OAC) and either knew they had Barrett's Oesophagus or suffered from persistent heartburn. The number who did not suffer from heartburn was much smaller. There is a school of thought that acid can cause problems without creating heartburn, and some people believe that this can manifest itself in the form of a persistent cough, for instance. Some people might have had a persistent cough as well, of course.
There is a strong apparent link between persistent heartburn, Barrett's Oesophagus and OAC, but I dare say that some people may have been diagnosed with squamous cell carcinoma when they had heartburn, so these things are complex. And not everyone knows which form of cancer they had anyway.
But thank you to all those who have responded to earlier polls, and we would be grateful if you would also have a go at this latest one. They are not very scientific, but can give some useful insights.
