Dr Hamer started his cancer research when he developed testicle cancer after his son was shot dead. He wondered if his son's death was the cause of his cancer. Subsequently he investigated and documented over 15,000 cases of cancer and always found the following characteristics to be present, which he termed the Iron Rules of Cancer.
The Iron Rules of Cancer
1. Every cancer and related disease starts as a DHS that is a Dirk Hamer Syndrome, which is a serious, acute-dramatic and isolating conflict-shock-experience. It manifests simultaneously on three levels, psyche, brain and organ.
2. The theme of the psychic conflict determines the location of the focus or HAMER Herd in the brain, and the location of the cancer in the organ.
3. The course of the psychic conflict correlates with the development of the HAMER Herd in the brain, and the course of the cancer in the organ.
At the moment of the conflict-shock a short circuit occurs in a pre-determined place of the brain. This can be photographed with computed-tomography (CT) and looks like concentric rings on a shooting target or like the surface of water after a stone has been dropped into it. Later on, if the conflict becomes resolved, the CT image changes, an edema develop, and finally scar tissue.
How specific and precisely located these brain lesions are may be seen from the following: After a professional lecture a doctor handed him the brain CT of a patient and asked to explain it. From this Dr Hamer diagnosed the patient to have a fresh bleeding bladder carcinoma in the healing phase, an old prostate carcinoma, diabetes, an old lung carcinoma and sensory paralysis in a specific area, in addition to the corresponding emotional conflicts.
Amazingly, Dr Hamer was able to show that at the same time as the concentric brain lesion appears also the target organ CT may show such a concentric lesion. According to Dr Hamer this happens instantly when the psychic shock hits the subconscious level and this same second is the start of cancer. However, also other diseases can be caused by the same mechanism. How severe a disease becomes may depend on other psychological, energetic and nutritional factors but its nature and location are determined by the content of the conflict shock.
Hamer believes that the correlation between key emotional shock events, the target brain areas and the related organs has developed as an adaptation of our human evolution from similar programs in the animal world. When we unexpectedly experience emotional distress, an emergency repair program is set in motion, a biological conflict program with the aim of returning the individual to normal. Such programs can even apply to families or other groups.

What is interesting about this theory (and different from most theories in medicine) is that it makes predictions that you can test yourself.
