The objective of the study was to examine the association of the consumption of added sugar (ie, sugar added to coffee, tea, cereals, etc) and of high-sugar foods with the risk of pancreatic cancer in a study of  77,797 women and men aged 45–83 over a period of 7.2 years.

The study found:

(a) Those who consumed the highest amount of added sugar had a 69% higher risk of having pancreatic cancer compared with those who consumed the lowest.

(b) Those who consumed the highest amount of soft drinks had a 93% higher risk of having pancreatic cancer compared with those who consumed the lowest.

(c) Those who consumed the highest amount of sweetened fruit soups or stewed fruit had a 51% higher risk of having pancreatic cancer compared with those who consumed the lowest.

To conclude: High consumption of sugar and high-sugar foods may be associated with a greater risk of pancreatic cancer.

Krone notes that high intakes of sugar and refined carbohydrates and elevated blood glucose are strongly associated with the risk of cancer.

This study sought to find out if sugar and refined carbohydrates and elevated blood glucose were also associated with poorer survival rates after diagnosis of breast cancer.

Krone measured blood sugar in a group of cancer patients (some with active disease and some in remission) and found a significant lower average blood glucose in those in remission. 

This study shows that high intakes of sugar and refined carbohydrates and elevated blood sugar are strongly associated with the risk of cancer , and is also associated with poorer survival after diagnosis for early breast cancer.
