The doctors have to do a biopsy to investigate whether there are cancer cells in tissues will have a short weapon more. May file a microdevice in 'area affected by cancer to monitor the progress of the disease and the tissue reaction to chemotherapy. Researchers at MIT, Massachusetts Institute of Technology, have created prototypes of these micro devices, the size of a grain of rice to be inserted into the needles with which the biopsy is done. " These little gadgets contain particles that bind with molecules of the part of tissue affected by cancer, then create a mass non-invasive but easily recognizable by magnetic resonance imaging, "said Michael Cima, an engineer and professor of science leader of the team that created these devices. Professor Cima microdevices has tested on mice." These devices are very sensitive, small mice suffering from cancer are implanted in the tumor and we have now detected by magnetic resonance imaging . " biopsy is the queen of analysis, an excellent tool for doctors to fight cancer, but the downside of this is that you have a reference measurement of 'performance of cancer only when collecting tissue , "says Peak. In practice, the biopsy can not monitor the development of cancer affecting a particular body part, other levies should be done on a weekly basis and analyze them. "With these DEVICES - continues Professor Cima - to measure the evolution of the tumor, and gives the same answer to an attack made with chemotherapy . The project also contributed to Professor Ralph Weissleder of Harvard Medical School.
