Cancer Growth is Promoted by Excess Levels of Insulin

Refined Sugar Causes Sugar Highs

In the previous post you learned that sugar highs provide all-you-can-eat banquets for your cancer cells. It is worse than that, much worse!

To fully understand the connection of sugar highs to cancer, you need to know the role of insulin to cancer growth and what happens when there is a rapid increase of glucose in the bloodstream (i.e. a sugar high).

Glucose is the primary source of energy for all cells.  Yet, glucose must be invited into a cell by insulin. The surface of every cell has insulin receptors. When insulin is attached to these receptor sites, the cell is signaled to absorb glucose.

Here is how it works. First, insulin binds to the receptor site on the surface of a cell. Once insulin is attached to the cell receptor, it binds to a molecule of glucose. Insulin is the key to unlocking the door of the cell to allow the glucose to be transferred from the bloodstream into the cell.

For our body to operate properly there needs to be a slow, steady supply of glucose. The pancreas regulates the blood sugar level in the bloodstream. The pancreas does this by releasing insulin and glucagon. These two hormones work together to ensure that the blood level stays in the normal blood sugar range.

As blood sugar levels increase, more insulin is released by the pancreas to enable cells to withdraw glucose from the bloodstream. When the level of blood sugar drops below normal, the pancreas releases the hormone glucagon which stimulates the liver to provide additional glucose.

You can avoid sugar highs by eating a diet of natural carbohydrates (fruits, vegetables, and grains). This diet allows the body to slowly supply glucose into the bloodstream.

Insulin is always accompanied by IGF.  IGF is a potent cancer-promoting agent.

The secretion of insulin is always accompanied by the release of another hormone called IGF (insulin growth factor). IGF’s role is to stimulate cell growth. Growth factors are molecules that, when bound to a cell’s receptors, stimulate division of that cell. IGF (insulin growth factor) is a powerful growth factor and a very potent cancer-promoting agent.

As long as the blood sugar level is above normal, more and more insulin and IGF will be released into the bloodstream in an attempt to bring down the blood sugar (glucose) level.

The higher the circulation level of insulin and IGF, the higher the risk of developing cancer, metastasis, and cancer recurrence.

David Servan-Schreiber, M.D., PhD sums it up in his book, Anticancer: “In short, sugar nourishes tissues and makes them grow faster. Today we know that peaks of insulin and the secretion of IGF directly stimulate not only the growth of cancer cells, but also their capacity to invade neighboring tissues.”

Dr. Servan-Schreiber reports that: “Susan Hankinson, ScD, of Harvard Medical School, has shown that in a group of women under 50, those with the highest level of IGF were seven times more likely to develop breast cancer than those with the lowest. Another team, composed of researchers from Harvard and the University of California at San Francisco in the United States and McGill in Canada, demonstrated the same phenomenon for prostate cancer: In their group of men, the risk was as much as nine times greater for those with the highest levels of IGF.”

There is a proverb: knowledge is power. When you know better, you can do better. Avoid the spikes of blood glucose caused by refined sugar and high-fructose corn syrup and you will significantly lower your risk of cancer growth and cancer recurrence.

Do you know how to avoid sugar highs?
