The immune system plays an important role in the surveillance and elimination of abnormal cells through a process called “immuno-editing”. Tumor cells that can “insulate/cloak” themselves with various mechanisms can help them hide from the immune system. Through natural selection, these tumor cells are able to persist and grow spreading cancer. The field of immunotherapy can be used to fight existing cancer and prevent new ones. This presentation covers recent research in this exciting field. Dr. Ramaswamy also shares her personal battle with cancer and how this form of treatment assisted her in putting her cancer in remission. Dr. Bhuvana Ramaswamy is a breast cancer oncologist, physician-scientist and Professor at the James. She leads the breast medical oncology section and is also the Chair of the Clinical Scientific Review Committee for the James. She completed her medical degree at Chennai, India and obtained her Membership at Royal College of Physicians at Edinburg, UK. She completed her fellowship in medical oncology at OSU and has been a faculty there since 2006. Her research interests are in drug-resistance and racial disparities in cancer outcomes. Her lab focuses on finding the molecular link between breastfeeding and risk of breast cancer. She has NCI funding supporting her work in the lab. She leads multiple clinical trials and has published widely. She was named as one the “top 27 breast medical oncologists” in the nation by Forbes in 2017 and has been named as a “top doctor” by Castle Connolly.
