Reasons not to purge?

Right now as my T is battling esophageal cancer, I thought I'd add this here, though his is from a different source....

Purging can result in esophageal cancer...and most people do not survive it. Rounds and rounds of chemo and or radiation, perhaps surgery to remove tumor or parts of stomach affected, maybe having to be fed by a tube implanted into the stomach....and still death later?

Hoping to encourage you to not take a permanent solution to a temporary urge.
