Tumor feeds on sugar?

I read from stillsmiliing that this cancer feeds on sugar. I am wondering about this and want more information. My dad had pancreatic cancer in 1998. Then I had been diagnosed with Breast cancer for the first time about 18 months later. I have now just finished (2003-04)with breast cancer treatments for the 2nd time. I am reading and hearing that bc is fed by sugar too. So is there some kind of a relationship with these 2 cancers in a genetic or familial way? because they both feed on sugar? does anyone know anything about this or have this experience? or where to find more information?
Thank you.

I have heard, through support groups, that pc does feed on sugar.

What does it mean "feeds on sugar"? PC patients must avoid sugar? Ther are 2 kinds of PC, exo...and endo...The endo...cancer has something to do with insulin, but is not common, the exo...PC cancer is present in 95% of the cases.
Thanks if anyone has an answer for this question.

Sugar is a toxic poison to our bodies. It just destroys us slowly. Look at all the obesity in north America and around the world. Natural sugars from fruits and veggies are ok. Man made sweeteners cause our bodies to malfunction in so many ways. To much sugar in our systems create a high acid level that cancers thrive in. Dairy products as well convert to starches which convert to sugars.All doctors should inform their cancer patients of this but they don"t

Tumors do feed on sugar and so does the rest of the body, especially the brain. Thats all it lives on. Tomors also grow thier own blood vessels, io facilitate even faster growth. As tumors require blood supply, sugar, and more to grow; anytime one of these is removed, the growth decreases. There are many carcinogens, but a positive family history (genes) are most prevalent. Please read this article i have placed in this message and hopefully have cited it correctely.ScienceDaily (Aug. 17, 2009) — Researchers at Huntsman Cancer Institute at the University of Utah have uncovered new information on the notion that sugar "feeds" tumors. The findings may also have implications for other diseases such as diabetes. The research is published in the journal Proceedings of the National Academy of Sciences.

"It's been known since 1923 that tumor cells use a lot more glucose than normal cells. Our research helps show how this process takes place, and how it might be stopped to control tumor growth," says Don Ayer, Ph.D., a Huntsman Cancer Institute investigator and professor in the Department of Oncological Sciences at the University of Utah.
During both normal and cancerous cell growth, a cellular process takes place that involves both glucose (sugar) and glutamine (an amino acid). Glucose and glutamine are both essential for cell growth, and it was long assumed they operated independently, but Ayer's research shows they are inter-dependent. He discovered that by restricting glutamine availability, glucose utilization is also stopped. "Essentially, if you don't have glutamine, the cell is short circuited due to a lack of glucose, which halts the growth of the tumor cell" Ayer says.
The research, spearheaded by Mohan Kaadige, Ph.D., a postdoctoral fellow in Ayer's lab, focused on MondoA, a protein that is responsible for turning genes on and off. In the presence of glutamine, MondoA blocks the expression of a gene called TXNIP. TXNIP is thought to be a tumor suppressor, but when it's blocked by MondoA , it allows cells to take up glucose, which in turn drives tumor growth. Ayer's research could lead to new drugs that would target glutamine utilization, or target MondoA or TXNIP.
Ayer says the next step in his research is to develop animal models to test his ideas about how MondoA and TXNIP control cell growth. "If we can understand that, we can break the cycle of glucose utilization which could be beneficial in the treatment of cancer," Ayer says.
