There are some clinical trials going on now that address possible ways to avoid progression:
1. Plant based diet
2. Taking a certain antibiotic ( can’t remember which one)
3. Curcumin/turmeric supplements
4. Taking Metformin (used for type 2 diabetes)
5. Chemo trials for really high risk or symptomatic (?).

I’ve read that losing weight or staying at a healthy weight is best. (Duh!)
Some people are trying the plant based diet and/or adding curcumin/turmeric supplements on their own.
