Good information. However, the video needs to be louder. It's very difficult to hear.

I have Barretts Esophagus and I have an endoscopy every two years. I have been taking Riveroxaban for six months and my next scan is due soon. Are there any bleeding risks with the scan?

Thank you. Can you explain if intestinal metaplasia develops (if it does ) into dysplasia before cancer may develop? Or does cancer develop either from metaplasia or dysplasia?

+This and that Intestinal metaplasia is a risk factor for the subsequent development of dysplasia and thereafter early cancer, but is not necessary for the development of dysplasia. Dysplasia can develop in any part of Barrett’s mucosa, but is more likely in that which has already undergone “metaplastic change”. The reason for this is because current evidence suggests that mucosa that has already undergone the change to intestinal metaplasia is thought to be more “unstable” than “normal” Barrett’s mucosa and therefore the likelihood of it developing into dysplastic mucosa is higher. However as already stated even “normal” Barrett’s mucosa may undergo the change to dysplasia, without transitioning via intestinal metaplasia. All cancers arising within Barrett's are thought to develop from mucosa that is dysplastic. Not all cancers arise in people known to have metaplasia, although this is a risk factor for the development of dysplasia and subsequently cancer. Hope that helps.
