Cancer Now Immediately Detectable With Microscopic Droplet of Blood

Cancer can now be detected immediately with just a microscopic drop of blood, a new study reports.


This is great news as survival rates should increase even for the hard to detect tumors. Some examples are pancreatic and ovarian cancer.These cancers tend to remain undetected until they are too advanced for treatment to work.Thus, survival rates are low.






Cancer: Detection In Microscopic Blood Droplet

Researchers at the University of Kansas have developed an ultra sensitive cancer-detection device. It is called the ‘3-D-microfluidic chip’ and it can detect cancer in a microscopic droplet of blood as well as in blood plasma.


The detector identifies and diagnoses the tiny vesicles, called exosomes, that blood cells produce. These blood cells contain important biological information that directs tumor growth and spread. They send messages to recipient cells that are important in several biological functions.


Tumors mirror the biological features of the healthy parent cells, eventually multiply, and outnumber the healthy cells.


Cancer: How 3-D Microfluidic Chip Detects Tumors

The micro chip searches for these exosomes and brings then into contact with the tool’s chip to be analyzed. To test its effectiveness, researchers used clinical samples from individuals with ovarian cancer. This disease is very difficult to detect and usually is only detected in Stages 3 or 4, when the tumor(s) has already metastasized.

They found that the chip was able to detect malignant tumors in even a microscopic amount of plasma.


Another benefit is that this detection probe is easy to manufacture and inexpensive to mass produce. Low costs insures that this tool will reach a large of of doctors, clinicians, and health practitioners.


In addition, the 3-D microfluidic nano chip has a wide application. All mammalian cells release exosomes, so it can also detect neuro-degenerative diseases, as well as breast and colon tumors.
