Can a Blood Test Detect All Types of Cancer?

New research published online in FASEB Journal, The U.S.Journal of American Societies for Experimental Biology, concluded that a revolutionary blood test that could detect any type off cancer was developed by British scientists. The test6 has been shown to diagnose cancer and pre-cancerous conditions from blood of patients with melanoma, colon cancer and lung cancer with a high degree of accuracy. Researchers assessed white blood cells and measured the damage caused to their DNA when subjected to different intensities of ultraviolet light that is known to damage DNA. They found a clear distinction between the damage to the white blood cells from patients with cancer, with precancerous conditions, and from healthy patients. They also found thatĀ  people with cancer have DNA that is more easily damaged by untraviolet light than other people.

Results were based upon blood samples of 206 people of which 94 were healthy and 114 were patientsĀ  in specialist clinics prior to diagnosis and treatment. Ultra violet damage was observed in the form of pieces of DNA being pulled in an electric field toward the positive end of the field, causing a comet like tail. The longer the tail the more the DNA damage and this correlated with patients who were ultimately diagnosed with cancer(58) and precancerous conditions (58) and those who were healthy (94). Further clinical research is evaluating the tests accuracy.
