In as little as three months, the brains of laboratory rats begin to change after being exposed to the air around congested Southern California freeways. “The evidence we are clearly seeing is the molecular cascade that can lead to the development of cancer,” said Dr. Keith L. Black, chairman of the department of neurosurgery at Cedars-Sinai Medical Center in Los Angeles.
Black is a world-class surgeon who pioneered research on ways to open the blood-brain barrier, enabling medicines to be used in the fight against brain cancer.
His war on brain tumors resulted in his being on the cover of a Time magazine special edition called “Heroes of Medicine,” which was published 1997.
