It&#x27;s not hard to make a somewhat reasonable hypothesis.<p>Cancer is not a binary category. In the natural course of a human life it can be observed that some &quot;cancerous&quot; cells cease to exist &#x2F; be problems, not from some external intervention, but merely through other signals and interactions within the body. Maybe some process detected something was wrong and set in motion another process that corrected it.<p>What controls these processes? Likely complex electro-chemical reactions that can only occur in certain environments. If a suitable environment does not exist, the reaction does not occur (how can it?).<p>Now, consider that the human consciousness can be observed to seemingly create complex changes throughout the body, including numerous electro-chemical reactions, and even changes of local environments (e.g. release of neurotransmitters and more general hormones).<p>If the appropriate environment is created for the appropriate reactions in the appropriate places to &quot;resolve a cancer&quot;, then it will happen.<p>Yes, you can argue about how much fine control a consciousness can have over it&#x27;s body. You can also argue about what reactions happen in which environments.<p>&gt;There&#x27;s a lot of evidence about how cancer cells work and little (if any) gives reason to suspect some sort of conscious connection would affect it.<p>Such as? You can only find something if you look for it. You would never expect to suspect a consciousness at work if you weren&#x27;t looking for it.
