Dr. Khan is a graduate of the University of Toronto, Faculty of Medicine (1992). After completion of his family medicine training in 1994, he joined a palliative home care team at his local hospital. This is how his focus on cancer patients began. In 2006, Dr. Khan co-founded Medicor Cancer Centres, the first integrated private cancer clinic of its kind in Canada. Since 2007, Dr. Khan gained international recognition for his work with the non-chemo drug dichloroacetate (DCA). He is privileged to be the first doctor in the world to prescribe off-label DCA to treat cancer with positive results. He is also the first in the world to demonstrate the curative potential of DCA when used as an adjuvant to chemotherapy or radiotherapy (one case published, others pending). Dr. Khan also uses low dose naltrexone (LDN) in his cancer practice.
