UCL scientists have developed a new technique for detecting the uptake of sugar in tumors, using magnetic resonance imaging.
A new technique for detecting cancer by imaging the consumption of sugar with magnetic resonance imaging (MRI) has been unveiled by UCL scientists. The breakthrough could provide a safer and simpler alternative to standard radioactive techniques and enable radiologists to image tumours in greater detail.
The new technique, called 'glucose chemical exchange saturation transfer' (glucoCEST), is based on the fact that tumours consume much more glucose (a type of sugar) than normal, healthy tissues in order to sustain their growth.
The researchers found that sensitising an MRI scanner to glucose uptake caused tumours to appear as bright images on MRI scans of mice.
Lead researcher Dr Simon Walker-Samuel, from the UCL Centre for Advanced Biomedical Imaging (CABI) said: "GlucoCEST uses radio waves to magnetically label glucose in the body. This can then be detected in tumours using conventional MRI techniques. The method uses an injection of normal sugar and could offer a cheap, safe alternative to existing methods for detecting tumours, which require the injection of radioactive material." Professor Mark Lythgoe, Director of CABI and a senior author on the study, said: "We can detect cancer using the same sugar content found in half a standard sized chocolate bar. Our research reveals a useful and cost-effective method for imaging cancers using MRI a standard imaging technology available in many large hospitals."
Tumors use large quantities of glucose to sustain their growth. By injecting normal, unlabeled sugar, UCL scientists have developed a way to detect its accumulation in tumors using magnetic resonance
He continued: "In the future, patients could potentially be scanned in local hospitals, rather than being referred to specialist medical centres." The study is published in the journal Nature Medicine and trials are now underway to detect glucose in human cancers.
According to UCL's Professor Xavier Golay, another senior author on the study: "Our cross-disciplinary research could allow vulnerable patient groups such as pregnant women and young children to be scanned more regularly, without the risks associated with a dose of radiation." Dr Walker-Samuel added: "We have developed a new state-of-the-art imaging technique to visualise and map the location of tumours that will hopefully enable us to assess the efficacy of novel cancer therapies."

and because it is useful and works, obamacare will deny it.
Obamacare will dispense sugar pills but good luck getting that MRI.
During the course of treating and caring for my elderly Lab with cancer, I tried most everything. As far as diet, it’s commonly believed that a high protein diet devoid of grain, starches and sugars is beneficial. Grains, starch and sugar “feed” a tumor or so the holistic conventional wisdom goes. I wouldn’t know if it’s true, but my dog loved the diet, his coat came back in glossy and he was happy. The cancer wasn’t what killed him.
PET scans are this way.
You gotta wonder why the first words from the oncologists mouth after giving patients the bad news isn’t “stop eating sugar to increase your chances of survival”.
Check out tumeric. It is a spice that has been shown to shrink or prevent tumors. We give it to our dogs- they love it mixed with water and put on their food. One of our dogs has had several mast cell tumors and had to have them surgically removed. None since we put him on tumeric.
And sorry about the loss of your loved one.
I also know a smoker who has mysteriously lost a severe amount of weight. If I were him I would want a full cancer screening. You don’t just loose a ton of weight without something using that energy.
Metformin, ask your MD about it...
Seems that something that highlights rumors can be turned up to fry them. Next step?
What way do you dispense tumeric?
I have bone lesion on my skull. It may have matastisized from the breast cancer.
I had a whole body scan now I’m fixng to have a PET scan on top area and they use the glucose injection. Later an open MRI for lower area.
For PET scanProtein only day before scan. No exercise, etc. Nothing 6 hrs before scan..
Glucose injection, then set for 1 hr, then scan. Cancelled twice. I’m claustrophobic.
Metformim is for Diabetics. How does that relate?
Yes, my husband had a number of PET scans. They are much more expensive than MRIs. Organs that normally have high sugar content can't be assessed to have cancer by a PET scan. The kidneys, for instance, will light up whether or not there is cancer there due to the usual sugar that is in the kidneys. When we would see the PET scans, organs normally with sugar were always lit up.
All energy sources are converted into sugar before your cells burn it. You can’t starve a tumor.
However, processed sugars no doubt cause unnatural sugar spikes. I wouldn’t be surprised if cancer is more likely to begin in a high sugar environment
Now I’m wondering why it all can’t be done in the ‘OPEN MRI, if the MRI uses the glucose also.
Also on another note: About cancer of the breast.
FIRST: You need to find out if you’re are ‘estrogen receptive positive’.
If you have had a complete hysterectomy and have taken hormones for years and years you are in BIG trouble. One can get by not taking hormones. Don’t think you can’t! Hormones feed the cancer. They did mine. Also I was drinking Soy beverage for several years and soy has flavinoids so it is also bad for ‘estrogen receptive positive’ cancers.
i heard that sugar feeds cancer
Metformin has been found to reduce cancer rates by 50 to 75% in those taking it.
I, too, was diagnosed with estrogen-positive BC. Prior to diagnosis, I didn’t take hormones of any kind, and I didn’t drink soy beverages. However, for a few years before diagnosis, there was one thing I was consuming in large amounts — SUGAR! :-(
Since then, I try to eat mostly veggies now. But, every once in awhile, I fall off the wagon.
I was going to say the same-how would this be different than a PET scan? Other than PET scans use radioactive materials—there’s probably more overhead with handling.
I’m not sure I agree with that. Cancers are cells that grow at abnormal rates; because of their growth rate, they use more glucose, which ALL cells do to grow. Using technologies like PET, we can see this more rapid uptake of glucose. This doesn’t mean that “sugars cause cancer.”
Most cancer cells lack the ability to manufacture their own glucose.
I didnt say it caused cancer.
That’s interesting. My husband takes it for his diabetes.

I am not sure how to do it with humans. We gave our dogs about a tsp a day. But there is much to read on its effects on humans and how to administer it- it will probably be pretty specific for different conditions so you should be able to find what you need easily online. I am so sorry about your health. I have had MRIs and was claustrophobic initially but they were able to inch me in little by little and I gor through it. One friend on FB had to have some medicinal help to get through it and he said it went pretty fast. I listen to music to help with the stress of going through it. Being sick sucks.
If you need to talk, just pm me.
OMG? Sugar. I am a sugar junky also. She didn’t say anything about eating ‘sugar’ I esp. like semi-sweet chocolate. Cakes, cookies. Crap no wonder they say your diet will have to change.
Now with no hormones, hot flashes, no sweets, No more soothing Starbucks, I will become another raging green hulk.
I really wanted to get away from SB anyway. One good thing.
Can one listen to music in PET?
I haven’t had a PET. Just MRIs and CAT scans.
the majority of healthcare costs are racked up later in life
cancer mostly inflicts the elderly in society.
the cost of health care is now on the fedgov
therefore, fedgov will never push to cure cancer (or other mostly elderly ailments) as they look to limit costs
Indeed. The amount of evidence that exists to show that cancer feeds on sugars would lead one to the conclusion that anything that drives insulin will promote cancer - to put it in simple terms.
Instead, the first option is, generally, to offer a treatment (chemo) that is, itself, carcinogenic?!?!
big secret - no cancer cure group wants to cure cancer anyway. if they did they’d push the things that actually do reduce and eliminate cancers.
PET scans use labeled 2-fluorodeoxy-D-glucose and expose you to ionizing radiation.
Please research where to get it online. I bought tumeric in the spice aisle at the grocery store but I am sure there are health food stores that have it capsuled up. Also, look at the studies that have been done. What I read gave me hope for our dog and he is doing well. It has been two years since his last surgery and no tumors have popped up.
I agree. I didn't say cancer cells manufacture glucose; the cells absorb glucose and convert it to energy, to help the cancer cell divide and grow.
Tribal Princess - I had a PET scan two years ago. They gave me a radioactive tracer to drink and kept me isolated for a bit... I guess so that no one else would be harmed by the tracer. It was a strange experience, but the scan caught what turned out later to be a benign cyst.
I don’t remember being allowed to listen to music or do anything but lie in the position they put me in during the PET scan.
TP and Nowhere Man - Here’s a link to the ACA with more information on turmeric:
I’ve never tried supplementing with turmeric. Maybe now is the time to look into it.
I’m getting the glucose injection and set for an hour and no stimulations before the scan.
No big deal there. I would like to listen to my ‘Mark Bishop’ music on my Ipod before and during the scan. Probably not.
Mark’s music helps me through the dentist visits.
Good luck with everything.
Thanks, one and all! Tomorrow at 2:45.
How did everything go with the scan?
Thank for asking. It was a PET. I took a Lorazapam and was fine. I opened my eyes a couple times and I think I’m going to get better at this.
Anthony at Radiology Assoc. is great. He helped me through the first whole body bone scan. I was pilled up for that one too.
Next comes the open MRI.
Glad to hear the PET scan worked out for you. I hope you find the open MRI to be very comfortable. I will say a prayer for you.
