One year after "cancer goggles" were first used in a successful breast cancer operation, Dr. Samuel Achilefu is still getting emails from surgeons all over the world, hoping for a chance to use them.

“We’ve been inundated,” he said from his desk in Washington University’s Mallinckrodt Institute, hours before receiving the 2014 St. Louis Award for his invention.

Achilefu counts 27 surgeries where his technology has been worn by doctors operating on patients with breast cancer, liver cancer and melanoma. An injected dye reacts with infrared light to make cancerous tissue light up, helping surgeons locate the tumor and separate it from healthy tissue.

He said he hopes the device becomes a cheaper, easier way for doctors to "see" tumors here and in the developing world. Because the goggles also project the surgeon’s view onto a computer screen, they could be adapted for use as a teaching tool.

Achilefu said the idea for the goggles was borrowed from other medical disciplines and born out of a need to reduce the number of instruments in a surgery room.

"Ophthalmologists use glasses. Neurosurgeons do the same thing, but with large microscopes,” Achilefu said. “The idea was what is the simplest device to create that is easy to use but still effective.”

Developing the goggles became a three year collaboration between radiologists, optical and sensory engineers, and surgeons — a tting development for the same radiology institute that invented the PET scan.

The St. Louis Award is given each year to honor a resident who has made an "outstanding contribution" to the community. Achilefu accepted his during a ceremony Wednesday evening in St. Louis.

Speaking by phone with St. Louis Public Radio, award committee president David Kemper said, “It just seemed natural,” to choose Achilefu for the honor.

“None of us knew him, but we knew of what was going on. We thought, 'Well, isn’t this fascinating, what a great contribution to society,'” Kemper said.

Achilefu grew up in the city of Aba, in southeastern Nigeria. After winning a government scholarship to study in France, he completed his studies at Oxford University before following a longtime mentor to the Mallinckrodt lab in 1993. He lives in the St. Louis area with his wife and two teenage children.

“I’m a good example that if you place anybody in a place and ask them to survive, they will. They will adapt to that language,” Achilefu joked. He speaks three languages uently: Igbo, English and French.

As for the future of the goggles, Achilefu said he’d like to see them become easily accessible to low-resource areas, such as urban centers and rural hospitals. He and his colleagues are gathering data to apply for FDA approval.

“I hope that in other developing parts of the world that can’t afford imaging technologies, this becomes affordable and useful for them,” he said.

Another step will be adapting the goggles to magnify the surgeon’s view to streamline brain surgeries. Achilefu said that ideally, the image would be sharp enough to be magnified so that even a single cell could be identified by a neurosurgeon.

“Medicine becomes more objective if you can see what you are treating.” Achilefu said. “You have the confidence you are doing the right thing to the patient.”

Picture of the goggles now. Abi you never hear say a picture is worth thousand words?

Respect to the Jews of Africa. Nigerians keep stepping on them but the world keeps embracing them. I remember a couple of years back when this news broke out on nairaland about the invention, trust them Yorubas to play it down with different forms of mockery, the news didn't even make front page back then. But that didn't stop this strong man, God bless Igbos of nigeria.

Although it might kill some to admit but the Igbos are nigeria's ticket to greater heights. Forget your bigotry and admit this truth then maybe, just maybe we can forge ahead from there

Where are those monkeys of hate from South West? I know you people will not invade this thread because it is a good news on the side of biafrans, if it was the other way round this thread would have been infested by those monkeys.

That is our son. We are proud of him!

powerful nations that are scavenging for oil resources would have targeted igboland if they were to be alone nd be called biafra,small nations suffer crises of war caused by powerful nations,to siphon their resources,besides no tribe is beta Dan d other,unity is power,protection nd development,if biafra want to separate,they should first take a look at d state of small nations with oil;Pakistan,baghdad e.t.c
