People who received the electromagnetic field treatment remained cancer-free an average three months longer than those who got only follow-up chemotherapy -- 7.1 months compared with four months, the researchers reported.
How long does it take for glioblastoma to die?
National Cancer Institute. Most patients with glioblastoma die within one to two years of diagnosis, the researchers said in background information.
Does glioblastoma cause recurrence?
Patients with glioblastoma experienced slightly better overall survival and delayed recurrence of their brain cancer if their heads were exposed to a type of electromagnetic field therapy alongside conventional chemotherapy, the Swiss research team found.
Can you give someone a placebo and expect their tumor to shrink?
However, he added that tumors generally don't respond to placebo effects. "You can't give someone a placebo and expect their tumor to shrink," Sampson said.
What is the new technology that uses sound waves to fight cancer?
And HIFU isn’t the only new technology using sound waves to fight cancer. Researchers from the University of Alberta in Canada have developed a technique that is as accurate as a biopsy needle. In this technique, the ultrasound energy activates tiny particles which use that energy to break apart cancerous cells.

What is a high intensity focused ultrasound?
A recent breakthrough in high-intensity focused ultrasound therapy (HIFU) technology has proven its use as an effective cancer treatment. A multi-institutional research team from China developed a semi-enclosed, spherical cavity transducer that can produce a focused, standing-wave field with a subwavelength-scale focal region and extremely high ultrasound intensity. The spherical cavity transducer appeared to generate tighter focal regions and greater pressure amplitude compared with the traditional concave spherical transducer. Researchers said the level of intensity generated by the new transducer design may lead to significant improvements in HIFU therapy. The findings were published in the Journal of Applied Physics.
