Researchers at the University of Michigan
have developed a pill that makes tumours light up when exposed to infrared
light.
The researchers say the concept has
been tested and proven effective in mice.
“We overspend $4 billion per year on
the diagnosis and treatment of cancers that women would never die from,” said
research leader Greg Thurber.
“If we go to molecular imaging, we can
see which tumors need to be treated.
“It’s actually based on a failed drug.
“It binds to the target, but it doesn’t
do anything, which makes it perfect for imaging.”
The researchers attached a molecule
that fluoresces when it is struck with infrared light to the drug.
Then, they gave the drug to mice that
had breast cancer, and they saw the tumours light up.
The targeting molecule has already been
shown to make it through the stomach unscathed, and the liver also gives it a
pass, so it can travel through the bloodstream.
The move could also catch cancers that
would have gone undetected.
By providing specific information on
the types of molecules on the surface of the tumor cells, physicians can better
distinguish between benign and aggressive tumors.
Moreover, using a dye delivered orally
rather than directly into a vein also improves the safety of screening.
The researchers say the new pill may
outperform mammograms.
