A team of scientists from the University of Queensland, Brisbane, Australia, developed a test, which in ten minutes allows the detection of cancerous cells and make an initial diagnosis faster.
The research, published in the journal Nature Communications, served to analyze the differences in DNA between cancer cells and those that are not damaged.

In all mature human cells, DNA carries modifications that are formed by a process called methylation that is genetically programmed, so that the genomic information in the cancer cells is significantly different from that in healthy cells.
The team led by scientist Matt Trau discovered that the difference in the process of methylation of cancer cells influences the physical and chemical properties of DNA.
Scientists have used this different behavior to develop a test that can detect cancer from a small amount of the patient's DNA. This test lasts only about ten minutes and your result can be seen at a glance.
He has been cutting hair and discovered that he has cancer.
The test was performed with 103 human DNA samples, of which 72 belonged to people with cancer and 31 were from healthy individuals.
The researchers observed that, at this stage of development, it is only possible to detect the presence of cancer cells, not their type or the stage at which the disease is found, and that more samples would have to be analyzed for a more detailed analysis. .
