Therefore it can be cured with some exterior stimulus, such as diet, herbs, radiation or chemotherapy.

Think of all those labs and studies, over 100 years worth and Science is not all that much closer than in the late 1800's in finding a cure to anything except for dietary deficiencies and infectious diseases and the use of Antibiotics .
