A San Rafael doctor took part in an investigation to determine the origin of brain tumors



Smith and Raphael Javier Orozco (41), together with the biologist Diego Marza (38), recently participated in a scientific breakthrough because they accurately identified the origin of brain tumors, which is a big step in their diagnosis and treatment.
In this context, Orozco, who lives in Los Angeles since the beginning of 2013, the year he decided to travel with his wife and two children, told FM Vos (91.5) that "with our work we were able to create a tool based on molecular biology. Able to simulate the DNA of different tumors and be able to differentiate by a small fraction of the DNA that some kind of tumor is in the brain. "
He explained that "the brain can have tumors that are created right there, are the main tumors that are born there, or they can be tumors that originate from another part of the body and then travel to the brain, and that's what we know metastasis." Once there, it is not easy to determine its origin " .
In conclusion, this is a "diagnostic tool which, through a small part of DNA, produces a kind of" barcode ", which allows us to know which part of the tumor body is coming from.
He claimed that this information is essential for medical treatment. "By knowing the source of the tumor, we can know how it is called, the surname and surname, ie, that this tool helps us identify the source, that is, if it comes from breast cancer, skin cancer or lung cancer, Often to travel to the brain, so in addition to knowing where it comes from, we know how it behaves, "he explained on the importance of the discovery, although he made it clear that the verification phase was still lacking.
On the beginning of the investigation, he said that "it started before I came to the United States in 2013. Here they have a strong history of work due to brain metastases mainly due to melanoma." When I joined, we were able to combine both breast and lung cancer, and we are associated with neurosurgery To be able to integrate primary tumors, that is, officially began work in 2013, and we were able to publish it a few days ago. "
"It is vital that the population is informed and aware of the tools available there, both for prevention and early identification, and both strategies affect patient survival, so it is important that they always know them," he said.
