Dr. Ian Gawler, a veterinarian, suffered from osteogenic sarcoma (a form of bone cancer) of the right leg when he was 24 in 1975. Treatment of the cancer required amputation of the right leg. After completing treatment he was found to have lumps in his groin. His oncologist at the time was confident this was local spread from the original cancer, which is highly aggressive. Gawler later developed lung and other lesions as well, and was given 6 months to live due to his metastatic disease.
Gawler decided to embark on an alternative treatment regimen, involving coffee enemas, a vegetarian diet, and meditation. Eventually he was completely cured of his terminal metastatic cancer. He has since become Australia’s most famous cancer survivor, promoting his alternative approach to cancer treatment, has published five books, and now runs the Gawler Foundation.
At least, that is the story he believes. There is one major problem with this medical tale, however – while the original cancer was confirmed by biopsy, the subsequent lesions were not. His oncologist at the time, Dr. John Doyle, assumed the new lesions were metastatic disease and never performed a biopsy. It was highly probable – the timing and the location of the new lumps following a highly aggressive cancer. But even a diagnosis that is 95% likely will be wrong in 1 patient out of 20 – which means a working physician will have patients with the 5% diagnosis about once a week. The standard of practice today would be to do a biopsy to get tissue confirmation of the diagnosis, and rule out the less likely alternatives.
