Currently on chemo#5. Have metast prostate cancer 6 years. No chemo side effects. Had bone pain several months ago but not any more. I feel the seaweed extract has slowed my progression. I also recommend far infrared therapy. I use the FAR heat mat for an hour a day at 55 degrees C. Like I said I feel normal with no pain. My scans indicate improvement and my psa dropped from 17 to 6 . My oncologist says keep doing it.
