Cancer is one of the leading causes of death worldwide and is characterized by uncontrolled growth and multiplication of cells.
Insulin is one of the key hormones in regulating this sort of growth.
For this reason, many scientists believe that having constantly elevated insulin levels (a consequence of sugar consumption) can contribute to cancer (14).
In addition, the metabolic problems associated with sugar consumption are a known driver of inflammation, another potential cause of cancer (15).
Multiple studies show that people who eat a lot of sugar are at a much higher risk of getting cancer (16, 17, 18).
Bottom Line: There is considerable evidence that sugar, due to its harmful effects on metabolism, can contribute to cancer.
