I mentioned that the processes in the blood are entirely different from those in the nerves; they are the antithesis of each other. In the blood-processes the urge is towards the phosphorizing element. When these phosphorizing processes take hold of what encloses or is adjacent to the blood, they lead to inflammatory conditions. But if the processes in the paths of the nerves themselves deviate into the adjacent organs and even into the blood, then impulses towards every kind of swelling arise in man. When these processes are carried over into the blood so that they affect the other organs in an unhealthy way, the formation of swellings or tumours makes its appearance. Every swelling or tumour is a metamorphosed nerve-process wrongly situated in the human organism.
