Sunnybrook’s Cancer Ablation Therapy Program harnesses a range of precision therapies to destroy tumours without the need for invasive surgery.

Cancer Ablation Therapy Program

The program has acquired three game-changing radiation technologies that will allow Sunnybrook to provide individualized, precision care to more patients, and conduct leading-edge research to invent the future of health care.

Canada Icon

Sunnybrook is the first in Canada to have this trio of highly specialized cancer ablation therapy machines.

Precision Icon

These precise machines will help change the way we target tumours and expand our individualized, patient-centred approach.

Innovation Icon

Our researchers will help perfect the way these machines are used to treat patients in the best and safest ways possible.
