DNA-Based Test Can Spot Cancer Recurrence a Year Before Conventional Scans (theguardian.com)

An anonymous reader quotes a report from The Guardian: A revolutionary blood test has been shown to diagnose the recurrence of cancer up to a year in advance of conventional scans in a major lung cancer trial. The test, known as a liquid biopsy, could buy crucial time for doctors by indicating that cancer is growing in the body when tumors are not yet detectable on CT scans and long before the patient becomes aware of physical symptoms. It works by detecting free-floating mutated DNA, released into the bloodstream by dying cancer cells. In the trial of 100 lung cancer patients, scientists saw precipitous rises in tumor DNA in the blood of patients who would go on to relapse months, or even a year, later. In the latest trial, reported in the journal Nature, 100 patients with non-small cell lung cancer were followed from diagnosis through surgery and chemotherapy, having blood tests every six to eight weeks. By analyzing the patchwork of genetic faults in cells across each tumor, scientists created personalized genomic templates for each patient. This was then compared to the DNA floating in their blood, to assess whether a fraction of it matched that seen in their tumor.

    First, We as humans recognized the similarity to the save game mechanism of video games and DNA a long time ago.

    We decoded DNA. Even the stuff you refer to as 'Junk DNA', and discovered some things that we as humans weren't too happy about. So. We altered things. We cured cancer. We learned of the origin of disease and how modern medicine had derailed. We learned who it was serving, why, and rewired things as we saw fit.

    So when you tell us that what you gleaned from DNA and how it in a sense lets you predict the future.

    We know. We've known for a long time now.

    Free will and choice necessitated changing this.

    No more tests telling us who we are and arent and what we can and can't be.

    You can take your 'bad karma' which you'll invariably try to send my way. Negative energy, right, for not being supportive of your system and ways?

    We dont want it anymore.

    As for cancer.

    We found the cure.

    You're going to have to quit dismissing stuff as junk, as fiction, as hallucinations in order to understand what that cure is.
