What If a Simple Blood Test Could Detect Cancer? | Hani Goodarzi | TED

Catching cancer at its earliest stages saves lives. But in a body made up of trillions of cells, how do you spot a small group of rogue cancer cells?

Catching cancer at its earliest stages saves lives. But in a body made up of trillions of cells, how do you spot a small group of rogue cancer cells? Biomedical researcher Hani Goodarzi discusses his lab’s discovery of a new class of RNAs that, when paired with emerging AI tools, could help detect cancer earlier, more precisely and even through routine blood work — potentially transforming our understanding of the disease.

      Yeah we do. For a long time now. But it won’t come out in a basic, standard test – that is usually done very quickly.
      You have to request a full blood test, or they will do it if there is suspicion of cancer, and is also usually done when doing something like a full body scan (CT, MRI and so on).

    The concept of this topic is irrelevant and very stupid considering the fact that cancer has already been decoded and cured long ago. Back in 2000 I read an article from the ’90s of how they cure cancer do babies umbilical cord cells. The new sales created other new cells and completely abolished the cancer cells. I’m pretty sure they still use this method in some ways, but the fact is this people are not knowledgeable of it which can only mean that it has been washed the side purposely.

      If it is positive – there is quite large percentage of results, that would actually suggest that you may have a cancer. More detailed checkup is required of course, but as a fast quick test – that could be also a starting point to do (as some types of testicular cancer make human chorionic gonadotropin, or HCG – the same hormone women make during pregnancy).

    There are companies that detect cancer with a blood sample very accurately, but they first need a tumor sample so they can create a fingerprint from it. Then they can see if the treatments are working or if the cancer is still there by sequencing the DNA from a blood sample because tumors release ctDNA into the blood stream.

    • @tannhauser5399

      February 1, 2024 at 5:37 am

      @asdf8948 – true, the detection of cancer, via blood sample, has been done for a long time now. If you do a full body scan, that woudl include full blood test, they can detect that.

      Also maybe not a great shortcut, but in case of men… try pissing on the pregnancy test and see what happens. If it is positive – there is quite large percentage of results, that would actually suggest that you may have a cancer.

    He’s explaining as if cancer is the ’cause’ of disease as supposed to being the result. As if cancer is an active thing like a virus or bacteria that ‘targets’ DNA in the body to spread as supposed to the body being in a state that causes DNA malfunction from smoking for example and cancer being the result. Something is afoot.

Sometimes people come into your life to show you what is right and what is wrong, to show you who you can be, to teach you to love yourself, to make you feel better for a little while, or to just be someone to walk with at night and spill your life to. Not everyone is going to stay forever, and we still have to keep on going and thank them for what they’ve given us!

For those who fit into one of these descriptors, it is the bright side that they will die an early death without available treatment, and thereby make an improvement to the gene pool for future generations?
