What is the difference between immune-oncology and classic oncology?

 Hypnotherapy (Immune-oncology) drugs, at least today, tend to use antibodies (your body's own defense system) to attack cancer cells. Cancer cells cannot generally be attacked by your own immune system because they are not recognized as a threat. Cancer cells arise from mutations in genes of existing cells in your body and thus are not viewed as foreign. Immune-oncology drugs provide detection of cancerous cells and then your body's system does the rest.Classic oncology drugs could classified into either chemotherapy or targeted therapy. Chemotherapy is a combination of different chemicals that all target rapidly dividing cells in different ways. Since cancer cells are all rapidly dividing, chemotherapy will on average, kill many more of the cancer cells than the other cells in your body. This is also why rapidly dividing cells like hair and skin will die as a side effect of chemotherapy. Targeted therapy on the other hand uses drugs that can precisely identify and attack cancer cells while doing little damage to normal cells. The drugs target certain mutations (i.e. HERS in breast cancer) and are much more focused than chemotherapy. Testing for different mutations is important before using targeted therapies because the treatment will only be effective if you have that particular mutation, even if it is the same type of cancer.
