You are so wise, Forest, and I love this forum because of it. I left another TMS forum that had become quite radicalized.
Awwww,
@chickenbone, thanks for your kind words!
Tom, I don't think that our positions are so different. As I mentioned in my post, the mind can affect a huge number of conditions (including cancer) and reducing stress and having a positive attitude will help someone with their cancer.
I think that we can agree that mindbody approaches will help in both preventing and fighting cancer. The question is, how much will they help? And, can surgery, chemo, and radiation extend someone's life as well? (The choice of whether to use any given therapy is a personal one and I wouldn't want to make that choice for anyone. However, we can objectively ask whether a given therapy will extend someone's life.)
On pages 3-4 of The Divided Mind, Dr. Sarno distinguishes between two types of psychosomatic/mindbody conditions:
- "disorders that are directly induced by unconscious emotions," such as TMS and its equivalents and
- "diseases in which unconscious emotions may play a role in causation, but are not the only factor." (the italics are in the original text.)
That sounds about right to me. The mindbody connection may have some effect on cancer, but it is not the only cause.
So what are the other causes? Well, if we want to think rigorously about cancer, we have to think about what is known about cancer. A cancer is a group of cells that is growing (dividing) uncontrollably, due to a change in their genetic makeup. My understanding about the current thinking on mindbody effects and cancer is that chronic exposure to stress hormones are what facilitate the genetic changes. However, once these genetic changes are in place, they are in place and the cells will continue to divide no matter what our emotional state is. (Chronic stress can suppress immune system function which so I'm not saying that there is no mindbody effect, just that those cells don't care what you think - they will keep growing as long as they get enough food.)
If we want to think about the relative sizes of mindbody effects and non-mindbody effects in cancer, let's look at populations where the mindbody effects would be very strong. For example, if the mindbody effects were huge, we would expect to see much higher rates of cancer in nations that had been exposed to great chronic stress, such as war or political purges. Yet, one doesn't hear of massive cancer outbreaks during wartime or even long after wartime. Perhaps those results exist and I'm just not aware of them. Similarly, since a repressive emotional style in adulthood is linked to negative events in childhood, we should expect to see much higher cancer rates in people who have had childhood sexual abuse or other adverse childhood experiences (ACEs). There is some evidence of this, but it doesn't seem to be overwhelming:

In terms of whether conventional treatments work, there are massive amounts of data on this. I'm lucky to know a number of doctors and researchers and I really admire the ones who I know. Sure, they're not perfect, but who is? They work hard at what they do. And while there aren't as many TMS studies as I might like, Howard Schubiner has already done one Randomized Controlled Trial:

Here's the bottom line: I had TMS for a very long time and I still have the TMS personality. But I'm really not worried about it giving me cancer. I think I'm fine.
And, if I get cancer some day (as anyone might), I'm going to turn to my doctor for advice. I'll make sure that I find one that I trust, of course, but only a professional can sift through the mountain of evidence regarding various treatment options.
