NSAIDS were supposed to prevent colon cancer in people with familial polyposis, as far as I know this did not pan out in clinical trials.
I wouldn’t hold my breath until the effect is seen in clinical trials and then confirmed with further independent testing.
The nagging thought is how many cardiovascular cases the lawyers will pick up. Give old men Celebrex to old men and most of them with die with cardiovascular events. Of course if you don’t give them Celebrex and most of them will die of cardiovacular events but that won’t stop the lawyers.
Time to go to bed. I have old men repeating in brain.
