Margaret and others on the list have questioned stimulating the immune system of someone who has a cancer of the immune system- and while many of us agree with the basic concept, many of us work to boost our immune systems.  Well, maybe this is some of the answer.  Certainily, more research is needed.  David

"Scientists have been working for years to use the immune system to eradicate cancers, a technique known as immunotherapy. The new findings prove an alternate to this approach exists: When the cancer can't be killed with immune attacks, it may be possible to find ways to use the immune system to contain it. The results also may help explain why some tumors seem to suddenly stop growing and go into a lasting period of dormancy."

The study appears today in the advance online publication of Nature.
