Thanks to David, members of the group at Guildford, and indeed many others, Cancer Research UK have now revised the way that they present information about oesophageal cancer on their website. This is something of a trial run, and the approach may be extended to other cancer types in due course. This is particularly important if you have just been diagnosed, especially when there is a lot of misleading information available on the internet.
So thank you to those involved, and to CRUK. They are interested in any feedback, by the way.
