New blood test can detect 8 types of cancer

New blood test can detect 8 types of cancer

The advances in science for the identification of tumors increasingly early has evolved enough. Recently, researchers at Johns Hopkins University in the United States have created a new blood test that can identify eight types of cancer before the disease evolves and spreads to other organs.

The test, called CancerSEEK, will have the estimated cost of $ 500 (something around $ 1,600 today - figure searched on 1/23/2018), say the researchers in the article published in the American scientific journal Science.

The research was done with 1,005 volunteers who had symptoms who already had a pre-diagnosis of cancer, and who were diagnosed with a blood test with an accuracy rate of about 70% in total. The cancers found by the examination were: ovarian cancer, liver cancer, stomach cancer, pancreatic cancer, esophageal cancer, colon cancer, lung cancer and breast cancer.

Some types of cancers, such as ovarian, liver, stomach, pancreas and esophagus, there are no screening exams available for persons at medium risk, however, CancerSEEK was able to identify these five types, with a sensitivity rate of 69% to 98%. , including the anatomical location of cancer in 83% of cases. The non-invasive test is based on a combined analysis of DNA mutations in 16 cancer genes and at the levels of 10 circulating protein biomarkers. Although promising, scientists point out that further testing and enhancement of the technology is still needed before it reaches the market.

The mouth can be a great access for the entrance of bacteria. And if the hygiene of the place is not performed correctly, these microorganisms create a bacterial plaque that lodges in the teeth, near the gingiva, to cause a picture of inflammation: gingivitis. The problem has been increasingly present in dentistry and calls attention of health professionals.

Robert was born on 26 November 1911, in Amiens, France. His secret to success in racing is stretching and adding a little honey to the water he drinks while riding. He started cycling seriously at age 68, since then he trains every day for an hour. Three years ago, the centenary traveled 26,927 kilometers in one hour, breaking his own record in the category over 100 years.
