Blood examination detects bowel cancer even without symptoms

The important one that locates the bowel is already circulating in the US, but has not yet been approved by the country’s drug organization. This is a blood test that accurately detects colon cancer in people who still may not have experienced symptoms and without having an increased risk of developing it. According to US and Canadian scientists, the examination identifies fragments of genetic material that release cancer cells and advanced pre-cancer tumors into the blood (CTDNA). Researchers tested it on thousands of volunteers, finding it detects the disease with an accuracy of 83%. However, its effectiveness in pre-cancer tumors was reduced. Although it is already circulating in the US, it has not yet received the approval of the country’s Food and Drug Administration (FDA). The FDA decision is expected within the year. Colon cancer is the third most common in adults (first breast and lung cancers). Early diagnosis can prevent more than 90% of deaths due to it. However, more than one in three adults who should have a pre-emptive colonoscopy examination are not subjected to it. The development of a simple blood test could increase pre-symptomatic control, researchers say. The new study The new findings are published in the New England Journal of Medicine medical inspection. 7,861 volunteers, aged 45–84, joined the study. All of them were subjected to colonoscopy and blood tests to compare their effectiveness. The blood analysis accurately detected 83.1% of the cancers detected by colonoscopy. However, at 16.9% colonoscopy revealed a colon cancer and the examination did not. Blood analysis was much more accurate in colon cancers, even if it was an initial stage. On the contrary, he had much less sensitivity (13.2%) to pre-cancer lesions, which could eventually develop into cancer. “These findings suggest that blood analysis is as effective as other diagnostic tools, such as faecal examination. It is, however, inferior to colonoscopy, which is considered the most accurate diagnostic method for colon cancer,” said supervising researcher Dr. William M. Grady, from the renowned Fred Hutchinson Cancer Center, in Seattle. Large bowel cancer is rapidly increasing, especially in young people (age under 50). Doctors now see even 30 – year – olds suffering from him. Source: iatropedia
