Introduction: Since the implantation of Flexner report in 1910, it was instituted that the medication of choice considered scientific were the ones produced by the pharmaceutical industry. According to Hippocrates, the father of medicine, we need to use older ancient medical traditions prior to the knowledge we have nowadays. So, if we analyze from the point of view of Traditional Chinese Medicine, cancer comes from energy deficiency and formation of internal Fire. In research analyzing the energy of all my patients in Brazil from 2015 to 2020, before the COVID-19 pandemic, I demonstrated that 90% of all of them, were in the lowest level of energy, in the five internal massive organs of the Five Elements theory of Traditional Chinese Medicine. These organs are Liver, Heart, Spleen, Lungs and Kidney. Each organ is responsible for the production of one internal energy for our health, for our survival and our immune system among many other functions. If we analyze these patients nowadays (in 2025), we can see that 100% of the population globally are in this situation. This is caused by the modernization of telecommunication after the implementation of 4G and 5G technology, leading to a state of a GLOBAL IMMUNODEFICIENCY. Cancer nowadays is also caused by this lack of energy inside these five internal massive organs, due to the fact that our energy is responsible for control the abnormal growth of malignant cells inside the body and when this condition is disrupted, the malignant cells can growth without control leading to cancer formation. The prompt treatment replenishing the energy of these five internal massive organs using highly diluted medications according to the theory of Constitutional Homeopathy of the Five Elements Based on Traditional Chinese Medicine created by myself in 2015 , can increase again the energy of our body and can increase our immune system, leading to control the abnormal growth of malignant cells inside the body, curing the patients suffering from this disease. To show how quick we can cure this disease, I will show four cases reports of patients suffering from cancer (2 women with breast cancer and 2 men with prostate cancer). The first was a 46 years-old female patient that had a right breast cancer of about 9 cm in diameter and between the time to do the surgery, I measured the energy of her five internal massive organs and all of them were in the lowest level of energy, rated one out of eight. She began to treat this condition using acupuncture, and replenishing the energy of these organs and in one week, this tumor reduced to 3cm, without using chemotherapy or radiotherapy or surgery. The second patient was a 36 years-old female patient with a breast cancer of 5 cm and using these highly diluted medications according to the theory of Constitutional Homeopathy of the Five Elements Based on Traditional Chinese Medicine and acupuncture, she reduced this tumor to 1cm in 4 hours of ingestion of these medications. After one day, this tumor disappeared completely. The third case report was a 60 years-old male patient with prostate cancer. Before he went to robotic surgery, his PSA was 20ng/dl. After this surgery, it increased to 40 ng/dl. After begin to use these highly diluted medications to increase the energy of the five internal massive organs, to increase his immune system, the PSA reduced to 0,2 ng/dl in the first month of treatment and to 0.02ng/dl in the second month of treatment. The fourth case report is a 76 years-old male patient with prostate cancer with initial PSA of 10,3ng/dl. After two months of treatment, using highly diluted medications according to Constitutional Homeopathy of the Five Elements Based on Traditional Chinese Medicine, Chinese dietary counseling and acupuncture, his PSA reduced to 5 ng/dl after two months of treatment. The conclusion of this study is to show that cancer has a cure and we need to treat the cause nowadays, that it is to increase the energy of the five internal massive organs of the Five Elements theory of traditional Chinese Medicine using highly diluted medications according to the theory of Constitutional Homeopathy of the Five Elements Based on Traditional Chinese Medicine created by myself. The use of any highly concentrated medications used in the conventional treatment can reduce even more these energies and lead to complication or death of these patients suffering from this disease.
