I had a total esophagectomy 4 years ago due to acid reflux. i still have acid reflux to this day even worse .can i get throat cancer from the reflux ?

Oesophageal cancer: Acid reflux causes stomach acid to splash up and into the lower portion of your esophagus. While your stomach has a lining that protects it from the acid, your esophagus doesn’t. This means that the acid can cause damage to the tissue cells in your esophagus and throat. Sometimes the tissue damage from acid reflux can lead to a a marginally higher risk of developing oesophageal and throat cancer.

Very unlikely: If the entire esophagus was removed, the chances of getting Barretts esophagus from the continued reflux is very unlikely. Having said that, if you are still having symptoms, it bears periodic evaluation to see how severe the inflammation is. You also should be treating the reflux to keep the symptoms under control. Good luck.
