What lifestyle measures can help prevent oesophageal cancer?

In response to a question on healthshare.com.au

Lifestyle is important, but there is no “magic bullet”, and oesophageal cancer is one of the cancers that is becoming more and more common.

Early detection can improve the chances of surviving oesophageal cancer. The best test for early detection is a gastroscopy. Some of the “danger signs” include the new onset of heartburn or reflux; difficulty swallowing; weight loss; pain on swallowing; or a change in previously-stable heartburn or reflux symptoms.
