Great update from "Hacksaw" Jim Duggan ... the wrestling legend just completed radiation treatment for cancer -- and celebrated by ringing the bell at the facility.
The 68-year-old made the announcement with an IG video -- just weeks after his cancer returned from a previous battle in 2021.
Duggan revealed in May he had to do 8 weeks of radiation treatment ... and as of this week, he's finally done with the grueling process.
"For eight weeks I've been coming by looking at this bell, listening to the other folks come by and ringing the bell and looking forward to it," Duggan said in the video.
