I dealt with a superlarge stone/cyst myself. Raw foods are not recommended. Maybe red salmon with raw Celery
and onion and parsley would be good. The traditional cleanse of a tea made from gravel root, hydrangea, and marshmallow root taken daily for 30 days would help. Electrical frequency machine would help. All kinds of fish, warm baths, and staying warm would help. Avoid coffee, sugar, soda pop. Seaweed/miso/fish soups (haddock) are helpful. The traditional tea has strong dissolving effect.
