A recent study reveals that a revolutionary blood testing can now detect five types of cancer tumor marker which are beneficial for early detection. Few available laboratory tests today are available to detect tumor marker that hinders early detection for an intervention.
The new DNA blood testing for tumor marker can identify womb, lung, stomach, colon, and breast tumor, NHS reported. The test works as it specifically points out defected DNA that causes cancer growth and defective cells. A particular human gene called ZNF154 is said to analyze cancerous gene that is probably inherited from a family member.
The DNA blood test is said to detect 1 percent possible cancerous tissue cell, as it can fairly be observed from the rest of 99 percent healthy DNA strand. Although the findings are conclusive the scientific world is still not convinced of the truthfulness of the method.
Issues that DNA testing faces today includes if whether or not it will make a huge impact in treating cancer as not all are convinced of its effectiveness. Another argument is the question if it will improve the current diagnostic method of detecting cancer.
Meanwhile, CNBC called the DNA testing as "revolutionary" since it can detect cancerous cells. Dr. Victor Velculescu from Johns Hopkins University Kimmel Cancer Center, Oncology and Pathology Center believes that DNA blood sample will soon become a part of laboratory examination for physical testing. He also added that early detection as it allows for surgical removal of the tumor that gives a higher chance of cure.
In addition to the report, Dr. Velculescu mentioned that early detection will allow the individual and the health care team to assess the kind of intervention needed as staging is necessary for treatment application. However for late stages, full recovery may be impossible as the cancer cell metastasis may have already spread to other areas of the body that medicine may not be able to penetrate.
