Diagonsed w/ low grade prostate cancer in 2002 (confirmed w/biopsies). Various suggestions from drs. - radical to watchful waiting. Sloan Kettering studies suggested GCP might be effective. I started 1.5g daily. PSA went "down" to 6 range and has basically stayed there ever since. Routine exams show no lumps/nodules. Still on 1.5g daily. Only side effect is occasional loose bowels. Expensive, but ...

I've taken GCP for about 9 months since my low volume prostate cancer diagnosis -- while my cancer seems under control (which may or may not be due to GCP), my white blood cell count has been going down rapidly -- I've read that genistein can impair immunity and lower white blood cell counts -- I'm going to cut back on GCP intake and have my WBC retested

Late 2009 I was told my metastatic prostate cancer was stage 4 and pressed to undergo chemotherapy because my lung mets were progressing 15% on successive measurements. My oncologist kindly referred me their PHASE 1 drug trials. I started taking Quality of Life's GeniKinoko (GCP)and ImmunoKinoko 750 (AHCC), 4 pills of each daily, after getting no benefit from stupidly underdosing another AHCC because it was so expensive. Because I am an Alternative (up to date) medicine loudmouth I was not liked by the Institute. I finally was admitted, after many tests, to Acceleron trials, and told they knew the dose and that it was helpful. The evening of the same day they called and told me I was disqualified because I had a regression in my lung mets. I left the Institute. I am still alive and healthy, doing all the maintenance on a fine house I rent. DON'T UNDERDOSERead More Read Less

I am experiencing very sore breasts after drinking Silk soy drink and also swelling of the breast - it's the only different thing I have done and it must be related. I also was taking Citracel which has genistein in it as does soy. Iwas hopeful the genistein would help with bone density
