    Should cancer patients avoid sugar?

    I learned last week from my oncologist that sugar feeds cancer causing it to grow. However, some cancer patients I know continue to eat cookies, cakes, etc. Isn't this bad for you? Shouldn't we stay away from sugar if it can cause tumor growth? Am I missing something?

      Yes it is bad for you, but not because you have cancer. Too much sugar is just as bad for people who don't have cancer. But sugar does not cause tumor growth nor does it feed cancer to grow any faster.

      I agree with Nancyjac. Sugar may be bad for you, but not because you have cancer. No one complained the time I brought donuts to the treatment center.

      Ok.... what about the PET scan? My doctor said they inject me with radioactive sugar dye to find where the sugar collects, because that is where the cancer feeds and grows. This is what led them to tell me to stay away from sugar.... they said I can have absolutely NO sugar for 24 hrs before the PET scan bc if I did, my body would light up with sugar in my system. The PET scan tells them if there is cancer and where. My PET scan is today.

      There is a big difference between the sugar we eat and the sugar (glucose) that is in our bodies. Everything we eat, not just sugar, eventually turns into glucose in out bodies because that is what we use for energy. We can't survive without it. Glucose fuels the metabolic activity that is required to support our immune systems to help heal or prevent infections and inflammations . A PET scan works by infusing a mega dose of glucose with contrast that will go to the areas of the body that need the most metabolic activity such as cell growth, fighting infections and inflammations, etc. Those areas of high metabolic activity are already there, the glucose merely highlights them for identification, it does not cause them. The fasting requirements prior to the scan are solely to enhance the reliability of the scan results by temporarily depleting glucose (the 24 hour fasting) levels so that the glucose infusion (immediately before the scan) will more predominantly show the areas of high metabolic activity during the scan.

      Just because certain scanning techniques i.e. PET scans use sugar along with other agents to show if tumours are present by hilighting the uptake of a tumour, people are often under the perception that sugar is harmful and makes cancer grow. The body takes sugar from all foods and only uses what it needs. Many know turmeric kills cancer cells, however it is simplistic to the extreme to say eating it will cure cancer as the active agents need a complex transport system to reach the affected cells. Lets hope the magic bullet to reach all cancers is happening in a laboratory soon!

      A well-balanced healthy diet is good for everyone with or without cancer, when I was too ill to eat I had live on sugary things as it was the only way to get anything to stay down.

      I still eat sugar in my diet and I don't know the answer, but if you read those alternative treatment things, they sometimes say that sugar feeds cancers. I have never had a Dr tell me this or advise me not to use sugar in my diet though.
