I sauna almost every day.  I believe that the process helps me to detoxify (after years of chemo and radiation) and it relaxes me.  I have read that raising one's body tempurature may make one's chemotherapy more effective.

This forum and the beating-myeloma.org site lean toward those issues that are non-conventional in nature for two main reasons. One, the acor and mmasupport list cover conventional therapies and two, my personal experience is dominated by non-conventional issues.
