At The Princess Margaret, it is understood that three of the scariest words are “You have cancer”. For more than 70 years, PMCF has been illuminating new paths forward in cancer diagnostics, research and exceptional care. With discoveries like stem cells, making bone marrow transplants possible, and the pioneering of immunotherapy through our discovery of the T-cell receptor, Princess Margaret Cancer Centre is a world-leading beacon of hope against the encroaching shadow of cancer.
