I know this post is 5 months old, but I thought I'd comment regardless...
Every"thing" begins at the thought level both in the conscious and subconscious mind. From there, we shape and mold reality. Our thoughts lead to action and those actions lead us into or out of balance. Dis-ease is a state of imbalance. We create reality at many levels or what my partner terms as "harmonics". The short of all this is that yes we create our illnesses from our choices and they all start at the thought level.
BTW there is a lot more than anecdotal evidence for spontaneous remission from disease states but our medical disease industry has no interest in pursuing them scientifically because there is no money along that avenue.
There are many ways to influence harmony in the mind and body. My blog is exploring many of these ways. Please drop by and feel free to comment. //www.curezone.org/blogs/fm.asp?i=1509519
