This ensures that cancer patients have access to the best current thinking about cancer management and latest treatment options available. Oncology specialists from BIDMC join the Cancer Center's bi-weekly Tumor Board conferences via secure teleconferencing technology. They participate in the diagnosis and treatment planning of every patient.
