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.

Electroencephalogram: exam evaluates the functioning of neurons

Electroencephalogram is the test that evaluates the electrical activity of the brain. It is a quick, simple, and painless procedure in which the electrical impulses of the brain are amplified and recorded on a piece of paper. Our neurons function and communicate the basis of naturally generated electrical impulses.

Reducing sodium intake may cut stomach cancer risk

Reducing sodium intake may cut stomach cancer risk

(WCRF), the average daily food intake by the population is 8.6 g, 43% higher than that recommended. Second the researchers in general, stomach cancer is diagnosed at an advanced stage, making only 15% of patients have a survival for a period longer than five years. Therefore, Kate Mendoza, head of health information at the WCRF reinforces the need for preventive measures.
