CAR T-cell therapy is a groundbreaking form of immunotherapy used primarily in the treatment of certain types of cancer. It involves genetically engineering a patient’s T cells (a type of immune cell) to better recognize and attack cancer cells. CAR T-cell therapy represents a significant advancement in cancer treatment, offering hope for patients with certain types of cancers, especially those who have not responded to other treatments. However, it’s a complex therapy with significant potential side effects that require careful management and monitoring. The therapy is continually evolving, with ongoing research aimed at improving its safety and effectiveness.
