Closer to a blood test that can detect cancer

A research published few days ago in the media Science is proclaimed as a get through in the continuing search for an easy blood test. That could identify eight of the most ordinary types of cancer for five of which there is at present no known technique of cancer. Carried out by researchers at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins, this human being test combines two obtainable methods of this type of screening. Analyzing blood for both proteins and genetic mutations associated with breast, lung, and colon cancer Pancreas, liver, ovary, stomach and esophagus.

It is Called Cancer Seek, this “liquid biopsy” confirms to be 70% successful in detecting these cancers in 1,005 patients who had previously been discovered tumors. The success rate ranged from a astounding 98% in people with ovarian tumors to only 33% in patients with breast tumors. In 83% of the patients, the test could also point to two parts of the body in which the cancer was perhaps located. However, the blood test alone was 43% effective in identifying cancer in its early stages. This is exactly what doctors would want to get this type of screening test.

The doctors’ response to these findings was to highlight that this test. That researcher’s guess will cost only $ 500 could give vital and basic information to discover some types of cancer that are difficult to detect. In addition, they warned that we must act with caution to avoid instilling false expect that a patient is healthy, when in fact they do have cancer. Of course, it is also significant that a test of this type. That one day could perform during your yearly physical examination, does not give a false positive effect that produces nervousness.

In this, the screening test performed well. Since it indicated that, a person had cancer when he or she did not have it in only seven of 812 patients. That is corresponding to a rate of less than 1%. The next thing, according to the researchers, is to use the blood test in a larger group more than 10,000 healthy people who do not show signs of cancer. This prospective study, the researchers said, will help decide if the test can detect cancer previous than conservative techniques.
