Cancer is not caused by glucose or carbohydrates or we would not have had an increase in cancer with declining carbohydrate consumption.

Put in his own words, "the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar."

Three ways glucose causes cancer.
1. Glucose binds to protein thereby corrupting and damaging them. These molecules are called advanced glycation end-products (AGEs). When proteins are glycated, they don't function or function erratically. The enzyme that cleaves DNA is a protein. When this enzyme is glycated, its function is compromised, this is how cancer is created.
2. Insulin and IGF-1 stimulate cell division. Carbohydrate stimulates insulin and insulin stimulates IGF-1. Therefore carbohydrate stimulates cell division through that chain of event. This is how cancer is grown.
3. The mitochondria of cancer cells is shut down. One reason is that the mechanims for apoptosis is located in the mitochondria. Cancer cells can't kill themselves. It's one of the distinguishing characteristics of cancer cells. Since the mitochondria is shut down, cancer cells can't use fatty acids nor ketones for fuel. They must use glucose for fuel. This is due to the inability of the nucleus to metabolize fuel aerobically. The process is anaerobic. It's fermentation and produces substantially smaller amount of energy. The by-product is lactic acid. The point is, when we eat carbohydrate, we feed cancer since glucose is all that it eats.
And one more way glucose makes cancer possible.
Glucose is an immuno-suppressant. It suppresses the immune system thereby allowing cancer cells to proliferate uncontrolled.
Why do you say glucose is the main source of fuel for the body? Is it because it's used up first, then fatty acids, then maybe ketones if there's a need? If it's a question of priority, consider alcohol, it is used before glucose yet we don't consider it the primary source of fuel. Glucose is not the main source of fuel for the body. Unless, of course, that's the main source of fuel you eat. It's not what I provide to my body. I give it only fat meat and water. Go over the math again and see if the idea still holds to scrutiny.
