An exhilarating development in cancer research in the last 10 years now consists of trials occurring at four cancer cure centers in America. The centers are utilizing an extremely responsive and new blood test developed at the Massachusetts General Hospital (MGH) in Boston. The test may transform the means for cancer healing. As tumors develop, they discharge cancerous cells into the blood stream. This fresh test pledges to identify the tiniest vestiges of cancer cells disseminating in the blood.

Dr. Dennis Haber, who is one of the researchers, has stated that, for every malignant cell in the blood, there are in excess of a billion blood cells in movement. In the latest test, a blood sample is moved across a microchip that is dealt with exceptional glue. Subsequently, Dr. Mehmet Toner explains that all these cells run through the chip, but only cancerous cells are detected by the chip and they bond with it, with the nontoxic cells being forwarded. The expectation is that, by appraising the amount and sorts of cancerous cells in the blood, physicians can ascertain whether a patient’s treatment is effective or not.

Dr. Elmer Huerta is a former President associated with the American Cancer Society (ACA). He has remarked that, in the treatment given by him, he observes if the tumor is lessening and vanishing in an X-ray and CT scan as well as an MRI. However, on occasions, only months later, a biopsy or X-ray illustrates if the treatment is effectual or not. During that period, crucial time is lost if the cancer lengthens. With this fresh test, physicians will be able to discern instantaneously if the patient still experiences cancer. This test, as per Dr. Pearson, will ensure that the follow-up of cancer sufferers will be more accurate and helpful. Pearson has stated that prudent usage of this technology will enable the detection of repetitive cancer cases earlier and fresh pills can then be supplied to neutralize that cancer.

All this research, however, is still in nascent stages and will take about five years to be comprehensive. Nevertheless, if it is successful, the researchers intend to popularize this test and make it broadly accessible.


Tests for diagnosing malignancy, or the presence of cancer within the body, have become quite sophisticated of late. However, researchers have now hit on an entirely new kind of diagnostic test all together. The test, being hailed as a next generation test involves the trapping of bits and pieces of cancerous cells, which break away from the tumors, spreading to the other parts of the body via blood.

This method can be used to gain access to the tumor and is being regarded as a form of ‘liquid biopsy’ at present. The only approved unit based on this system is Johnson & Johnson’s Veridex unit which has the capability of capturing only a few cells right now. The researchers, along with the various pharmaceutical companies, are working on creating newer devices which can be effective in trapping the cells in larger quantities. This will ensure an adequate quantity for the various drug companies to test their new formulations as well as give the medical professionals a chance to check the efficacy of their treatments.

Although the tests are being conducted at various academic laboratories across the globe, a few of the major pharmaceutical companies are interested as well.  The RNAscope technology, which had been focused at finding genetic materials so far, has now been adapted to look for cancer cells in blood. The technology is currently being used by the Advanced Cell Diagnostics, Hayward, California. NaturalNano Inc of Rochester, New York, wants to utilize its nano tube technology for the same purpose while the Japanese company, Sysmex Corp, is working together with Oncolys BioPharma, looking forward to developing a virus that can recreate itself while being easily identifiable by means of a fluorescent light that it emits within the tumor cells.

The New York based Vitatex of Stony Brook has also made claims of developing a blood test for capturing the cancerous  cells of a tumor which is thought to be at least ten times more sensitive than all other tests of similar nature.
