The results are apparently worth it. A New View Of How Tumors Behave Part of what has led Dr. Gonzalez to his nontraditional therapy is that he is skeptical of current thinking about how tumors behave. The size of the tumor doesn't matter to him. He actually prefers that the tumor enlarge, explaining that the body's natural response to a tumor is inflammation. If the body is doing what it's supposed to do, then inflammation should occur.
Inflammation can make a tumor look large on an X-ray.
The patient and the doctor may think he's getting worse when in fact he's getting better. The fact of the matter is that if a patient feels good they live longer. If they don't, they don't. According to Dr. Gonzalez, tumor biology is a lot more complicated than is presently appreciated. Whatever the relevance of tumor size, the hair test Gonzalez has developed motivates patients.
