The device used in the Massachusetts National Hospital did hit the tumor diagnosis in 96% of patients.

With only a mobile phone, a thin needle and a small molecular magnetic resonance apparatus it is possible to detect cancerous tumors. This was explained by the doctors at Massachusetts General Hospital in an article published in the journal “Science Translational Medicine”.

Thanks to this innovative system used by doctors could succeed in the diagnosis of cancer in 96% of patients, a figure higher than with the traditional biopsy.

"The system prevents patients undergo to procedures that are painful and potentially dangerous", said Cesar M. Castro from Harvard Medical School, Boston, and a member of the team that developed the procedure.

Through the collection of a portion of tumor tissue, which is subjected to an "immunohistochemistry" (a test that uses a specific procedure that "mark" the existence of cancer cells), is how they do the diagnostic of molecular analysis fast. To this are added biopsies and in some cases, previous surgeries.

The nuclear magnetic resonance micro device used “nanoparticles” as sensors that measure the chemicals in the cells and the device is connected to a phone, so that doctors can measure and read the data next to the patient's bed.

After scanning the tissues from patients to detect the expression of nine key proteins, the doctors correctly identified to 44 patients who had malignant tumors, and each of the diagnoses was confirmed with conventional biopsy.
