We’re lighting the way forward through discovery.

At The Princess Margaret, we understand that three of the scariest words are “You have cancer”. For more than 70 years, we’ve 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.
Yet, despite our progress, cancer remains a daunting challenge. By 2050, new cancer cases are projected to increase by 77%, with millennials experiencing the fastest rising cancer rates. This is why we are reigniting our commitment to transform cancer outcomes and create a world free from the fear of cancer.

But we cannot achieve this alone. We need your help to fuel this work.

See what it means to CARRY THE FIRE for cancer patients and their loved ones in our campaign video.

Join us in creating a world free from the fear of cancer.

And it’s made possible through the generosity of our donors. Learn more about how you can help fuel more cancer breakthroughs to create a world free from the fear of cancer at Why Give.
