Scientists have been able to develop a blood test to determine in less than 10 minutes whether a cancer type is associated with the patient.
The test is still under development, but if introduced, it will constitute a major change in cancer screening, making the diagnosis of the disease easy and inexpensive for patients and physicians alike.
The new method involves the use of a fluid that changes color to detect the presence of malignant cells throughout the body and presents the results within 10 minutes, without revealing the location or severity of the infection.
The test has a sensitivity of about 90%, which means that it will be able to detect 90 out of every 100 cancer cases, and then doctors will be able to perform additional tests to diagnose the specific type of malignant disease and its stage.
Scientists have discovered that cancer DNA and normal DNA bind differently to minerals and behave differently in water. So they added small gold particles to the water, turning the liquid pink.
If the cancer DNA falls into the water, it attaches to the metal molecules and the water stays the same color, but the normal (healthy) DNA attaches to the gold in a different way, transforming the color of the water in blue.
