Sugar and Cancer, a myth, never been proven.

I’ve read on the forum about not having sugar if you have cancer, this is a myth and never been proven. Your body needs glucose for energy, more so if you have cancer.

Hi Loimie,I take quite a lot of sugar in my diet and have not been told to avoid it despite having stage 4 cancer and 21 chemotherapy sessions over the last two years .

If you are active you need something to keep you going,and anyway it cant be worse for you us than the big C 🙂🙂 . Keep well,

Hello Dave, I’ve got stage 4 NSCLC, spread to one vertebrae. I’m under Christie’s. Picked up by accident on a CT scan of my bowel which was normal. Quite a shock really, no symptoms whatsoever. Anyway due to start immunotherapy next week. Saw my consultant last week, discussing diet and she said take no notice of things you read about sugar, it’s nonsense! I cycle a lot so need energy. It must me hard all that chemo, I was relieved I could have immunotherapy, didn’t want to lose my hair!! Bit petty really! And your right what can be worse than big C! Thinking of you and sending my very best wishes. X

october breast cancer awareness day is on the third Friday of october. Research continues to better understand the complex interaction between genes and environment in the development of breast cancer. A large, long-term study funded by the National Institute of Environmental Health Sciences is currently being conducted with the goal of understanding the causes of breast cancer .The Sister Study enrolled 50,000 women who have sisters with a diagnosis of breast cancer and is currently following these families for at least 10 years. A secondary study, the Two Sister Study, examines women with breast cancer diagnosed before age 50, with a sister, and their parents to further characterize possible causes of early-onset breast cancers. It also aims to provide valuable information about long-term survivors of breast cancer.
