Ottawa teacher Denis Raymond was just 26 in May 2013 when he was diagnosed with glioblastoma multiforme, an incurable type of brain cancer. On average, patients with glioblastoma multiforme survive for about 18 months after diagnosis. He eventually came across information about a clinical trial involving a type of electromagnetic field therapy. The tumour-treating fields, as the therapy is called, disrupts the division of cancer cells by delivering low-intensity, intermediate-frequency alternating electric fields. It is delivered through transducer arrays attached to the shaved scalp. The randomized control trial of the device would determine whether the therapy improved survival rates of patients with glioblastoma multiforme.
