Do I have cancer in me? What cancer could I have? The answers to these questions are scary but can save lives. This should now be possible very quickly. Researchers have one blood test develop.
It could revolutionize the diagnosis and early treatment of cancer: cancer can be largely cured with current knowledge if it is diagnosed early enough. For this, patients must undergo a balance and undergo unpleasant and expensive interventions.
Researchers have developed a blood test: it also recognizes cancer
The problem here is that cancer forms have different structures and therefore, several procedures, such as colonoscopy or mammography, must be used. Researcher University of Queensland in Australia have a blood test which develops in minutes cancer diagnosis can deliver.
The scientific team published its findings in the recently-released Nature Communication. They found a characteristic that differs from healthy cells in a blood test. "This unique feature of DNA at the nanoscale has appeared in all types of breast cancer that we have studied, as well as in other cancers, such as prostate cancer, colon and lymph nodes. " Sina.
The arrangement of methyl groups is crucial
Methyl groups, which change tremendously due to the presence of cancer, are the decisive factors. In healthy cells, methyl groups are distributed throughout the genome, the entire chromosome of a cell. In cancer cells, on the other hand, methyl groups accumulate in specific parts of the genome.
Australian researchers took the opportunity to develop the rapid test, which shows in a few minutes using nanoparticles of gold if cancer cells are present in the body. Discoloration of the test suggests the diagnosis.
Their next goal is to develop a more profitable variant that can also be controlled from the smartphone on the move. Until now, the accuracy of the test is 90%.
