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.
Causes of hemorrhoidal thrombosis The main factor predisposing to thrombosis is the fact of having external hemorrhoids. What may favor the event of the thrombosis itself are: Constipation Long periods sitting in the toilet Gestation Vaginal birth Anal sex Poor anal hygiene Ingestion exaggerated spicy foods and alcoholic beverages, as well as exaggerated physical exertion of the isotonic type.
If I put the pacemaker, will I be dependent on it? Not necessarily. But if you needed to put a pacemaker the more likely you are already dependent on it. At least some of the time you have bradycardia and it would be needed. How do I know if I need a pacemaker? People with very low frequency (less than 40 beats per minute) or pauses (?
