Cancer immunotherapy is a field that focuses on using the body's own immune system to combat cancer. This approach aims to enhance or stimulate the immune system to recognize and attack cancer cells, providing an alternative to traditional treatments like chemotherapy and radiation.

The podcast episodes "Why Cancer Rates Have DOUBLED Since 1990 | Dr. Matt Halpert" and "Cancer's power harnessed - lymphoma mutations supercharge T cells" discuss various aspects of cancer immunotherapy. The first episode explores the concept of personalized cancer immunotherapies, such as dendritic cell treatments, and the limitations of conventional cancer therapies. The second episode highlights efforts to improve T cell-based cancer immunotherapies by incorporating mutations from lymphomas.
