Rs.60 test detects early-stage prostate cancer

Sun, Apr 05, 2015, 03:39 PM
Washington, April 5, 2015: A test that costs less than $1 (Rs.60) and yields results in minutes is more sensitive and exact than the current standard test for early-stage prostate cancer, US-based researchers say.

The simple test, developed by University of Central Florida scientist Qun "Treen" Huo, holds promise of early detection of one of the deadliest cancers among men.

It would also reduce the number of unnecessary and invasive biopsies stemming from the less precise prostate-specific antigen (PSA) test that is now being used.

"It is a simple test. It is much better than the test we have right now, which is the PSA and it is cost-effective," said co-author Inoel Rivera, urologic oncologist at Florida Hospital Cancer Institute.

When a cancerous tumour begins to develop, the body mobilises to produce antibodies.

Huo's test detects that immune response using gold nanoparticles about 10,000 times smaller than a freckle.

Gold nanoparticles are known for their extraordinary efficiency at absorbing and scattering light.
