Scientists Make History by Breaking Blood-Brain Barrier to Treat Woman’s Tumor

Sunnybrook’s new method could open a new frontier in treating brain disorders.

Scientists at Sunnybrook Hospital in Toronto made history this week when they successfully developed a method to non-invasively breach the blood-brain barrier to more effectively treat the tumor of one patient, Bonnie Hall.

Take a look:

As Dr. Todd Mainprize explains, their technique is to “essentially tear holes in the blood-brain barrier (BBB) to allow the chemicals they want to successfully circulate around the brain.” In addition to her chemo medicine, Bonnie was given injections of micro-bubbles—or tiny bits of air—and then placed into an MRI. As the doctors hoped, the bubbles shook, ripped holes in the BBB, and then allowed the medication to seep through.

Doctors say that over the next few months, 6-10 additional patients will be treated using the new method to determine its widespread safety and feasibility in treating other brain-related diseases. For now, this breakthrough is incredibly monumental.


Seventy-five years ago, on January 27, 1945, the Soviet Army liberated the Auschwitz concentration camp operated by Nazi Germany in occupied Poland.

Auschwitz was the deadliest of Nazi Germany's 20 concentration camps. From 1940 to 1945 of the 1.3 million prisoners sent to Auschwitz, 1.1 million died. That figure includes 960,000 Jews, 74,000 non-Jewish Poles, 21,000 Roma, 15,000 Soviet prisoners of war, and up to 15,000 other Europeans.

The vast majority of the inmates were murdered in the gas chambers while others died of starvation, disease, exhaustion, and executions.
