Avodart and Proscar are commonly used in a process called triple androgen blockade or ADT3. The same logic that Avodart shrinks a normal prostate is considered useful that it can shrink cancerous prostate cells as well. Snuffy Myers book is based on diet and triple angrogen blockade, as is the practice by Bob Liebowitz.
Proscar - chemical name - Finasteride
Avodart - chemical name - Dutasteride
Bob Liebowitz study...Using Finasteride with HT...
Both have shown the ability to lower PSA post RP. There is also evidence that Finasteride can be used to maintain low PSA levels when using intermittent hormone therapy (IHT) during the periods that LHRH and GNRH agonists are stopped.
Another study is being expolred the is testing using Finasteride as a preventive or delaying agent in people with high risk of getting prostate cancer ~ African American or heredity cases.
