For a few years I’ve heard that cancer cells feed on sugar. Sounds like this is similar.
Yes. That’s how PET scans locate cancer in the body. They give you a radioactive sugar and then scan the body to see where it is located. Since cancer consumes sugar, the radioactive sugar lights up the scan wherever there is cancer.
My brother in law is a Radiologist who is board certified in Nuclear Medicine. I recently attended a radiology conference lecture he did on the history of PET scan development. He is now working with beta testing AI assisted PET scans as they give far more and more accurate detail.
