Immunotherapy, or biological therapy, is a type of cancer treatment that uses the immune system to boost natural defences to fight cancer. One immunotherapy approach is adoptive cell transfer (ACT) where cells from a patient or donor are extracted and genetically modified to become a specific type of white blood cell. They then take the white blood cell, improve its immune functionality, multiply the cells, and then return them into the patient. This treatment has been successful in treating patients with melanoma but less effective for treating ovarian, esophageal, stomach and breast cancer.
