It is important to create the distinction between what services complementary cancer care can provide, versus that of traditional oncology. Traditional cancer care focuses on the characteristics, histopathology and grading of the cancer cells and provides therapeutic inputs to eradicate the cancer cells through surgery, radiation or chemotherapy. A holistic or integrative model focuses on the terrain, milieu or metabolic environment in the body of the patient and its interaction with the cancer cells. The therapies chosen are to boost the innate host resistance and modulate the terrain so as to remove metabolic factors that favour tumour proliferation, progression, angiogenesis or metastasis. This is referred to as the Oncometabolic Milieu. A true integrative approach, providing the best advantage for the patient, combines evidence based strategies from both models.
