I know this forum is primarily for those with advanced PCA, yet I regularly see posts by those who've only recently discovered the disease and are not in such adavanced stages, being treated only with 1st-generation ADT. Thus, as a nearly 20-year survivor of PCa (first discovered in 2005) and 10-year survivor of metastasis (yet still tumor-free), I'd like to recommend some books that have been very helpful to me in this sometimes awful journey.
1) "Surviving Prostate Cancer without Surgery," by Bradley Hennenfent, M.D;
2) "Invasion of the Prostate Snatchers: Revised and Updated Edition: An Essential Guide to Managing Prostate Cancer for Patients and Their Families," by by Mark Scholz M.D. and Ralph H. Blum; and
3) "Becoming Half Woman & Other Adventures with Prostate Cancer: Journal 1: The First 18 years," by Terry Coleman.
