Radio waves erase pre-cancer cells in esophagus

How long before this becomes widely available? From Glenn Reynolds, a short item at PhysOrg:

In a study published Thursday in The New England Journal of Medicine, lead authors at the University of North Carolina-Chapel Hill report that the technology completely wiped out pre-cancerous cells in 90.5 percent of patients with Barrett's esophagus who underwent the procedure. Only 1.2 percent of patients went on to develop cancer a year later.

Among patients who got a sham procedure, 9.3 percent developed cancer.

Tough for the sham patients.
