There have been loose, amateur surveys that give a fair indication that there is a need for such a study -
"Is there a lower mortality rate (age of death) amongst Scientologists with cancer?"
There are some indications that the first question might achieve a "yes". There are strong indications that the second question would achieve a "yes",
The wild speculation is over the WHY, not whether or not more Scientologists die of cancer
I was asking for actual data. Of course there are questions about cancer rates, but no facts at all. Indications are not statistics or facts.
In order for you to ask WHY more Scientologists die of cancer you first must prove that more Scientologists do die of cancer. And the fact is no one has proven this.
