There are countless examples of lifestyle changes assisting prognosis While these are mostly anecdotal, they are very logical.
My PC is early stage, and my PSA has remained stable for the last 4 years. I use immune boosting herbs, olive leaf, astralagus, and anti oxidants.
I can not prove that this and lifestyle improvements have helped my PC remain stable, but it does seem that is the case. In any event my immune system has improved considerably: for example I have not had any severe sinus problems which used to be a common problem, so it's worthwhile for that in itself.
Many men on hormone treatment report that they cope better with less side effects if they improve their lifestyle and diet, so improvements could be worthwhile from that angle, in addition to other probable benefits.
Pfeifer Protocol: I would expect that a high % of men would benefit from it, as meny men indicate that they obtain good results from use of "prostasol" which is included in the protocol. There are various forms of "prostasol" from different suppliers but Dr Pfeifer's is very similar to the previous "Pc Spes". Dr Lee Nelson's book which is well worth reading has a chapter on "Pc Spes", including use by Dr Katz at Columbia Presbyterian Hospital, and tests by Dr Small at University of California San Francisco which resulted in good results for majority of men, even those who no longer responded to hormone treatment. Some men do have side effects similar to hormone treatment.
www.news-medical.net recently detailed one of the few trials showing that lifestyle may affect progression of cancer published in September issue of Journal of Urology. The 93 men had early stage PC. After one year PSA decreased in the group who made comprehensive lifestyle changes but increased in the comparison group.
The website www.yananow.net has stories from many men who have used various treatments including hormones. Look under mentors experiences.
Lee Nelson's book is "Prostate Cancer Prevention and Cure" Lee Nelson has used hormome treatment and radiation therapy himself. Although written a few years ago his book is very comprehensive and covers diagnosis, treatment options, lifestyle changes, diet, supplements .
www.health.groups.yahoo.com has a PC board with messages from a number of men who currently use "prostasol" some have used it and "Ps Spes" for considerable time.
Trust some of this information is of interest.
