Cancer less likely to relapse
The immune system develops the habit to attack cancer cells if they start to come back and this is known as immunomemory. When a person develops immunomemory, the immune system kills every cancerous cell and ceases the development of cancer once again. Immunotherapy can help the patients to stay cancer-free and stop the cancer relapse for longer time. The treatments of immunotherapy make certain changes in the cells that they manipulate the cancer cells in a better way thus making the immune system stronger. [7]
