Symbiotic life forms between algae and fungus, are called lichens:

http://en.wikipedia.org/wiki/Lichen

Human "Cancers" are also lichens, except in humans the symbiosis is between fungi and trophoblast cells. The white in all cancers is the fungal portion.

Trophoblast proliferation is stopped by pancreatin, chymotrypsin, as you know. If not stopped, it gives rise to environment surrounding the growth, which is conducive to proliferation of fungi normally present in blood - change of somatid forms discovered by Naessens in somatidian orthobiology and observed / proposed by several other workers, Enderlein, Bechamp the pleomorphism of particles always present in blood. The fungi multiply and in turn give rise to environment conducive to proliferation of trophoblast cells, and the cycle continues.

The cancer lichen is stopped by stopping the fungal portion, or digesting the protein of the trophoblast mass.

We can have an exercise, name off Hoxsey's treatment, Caisse's , Rife's, Livingston-Wheeler's, etc. and in every case it is attacking one half or the other of the lichen. Caisse powerful anti-fungal, emodin in the rhubarb root. Rife just killed all the fungal cells, the filterable Bt / Bx particles

Ever see a lichen devour a tree ? Lichen forms are kind of beautiful and on molecular level fractally similar to what humans call "cancer".
