Excessive intake of sugar, (partly due to the fructose fraction, but also glucose) or other simple carbs increases our risk of cancer. Our evolutionary past has instilled in us a natural craving for sugar which can be especially dangerous with a mutated phosphoinositide-3-kinase, or PI3K enzyme.
Fructose (from sugar and corn syrup) worsens glycation, oxidative stress, mitochondrial dysfunction, insulin resistance, and chronic inflammation.
The sugar-fueled cancer concerns include:
→ breast cancer
Shown by a study of 4690 women.
Sugar may hasten the spread of breast cancer to the lungs.
→ colon cancer
→ colorectal cancer
This was shown by a study of 506 patients and 673 controls
This was also shown by a study of 1586 patients and 2485 controls
→ pancreatic cancer
This was shown by a study of 77,797 men and women
This was also shown by a study of 532 cases and 1701 controls
→ prostate cancer
→ stomach cancer

For maximum immunity: minimize consumption of simple carbs such as sugar.

Avoid a high sugar intake which is also a high fructose intake.
Sugar is especially hazardous for those genetically predisposed to obesity.
Sugar increases visceral fat – the most dangerous kind.
Sugar injures via an altered gut microbiome and causes leptin resistance
High sugar intake injures via higher levels of insulin which is the fat storage hormone.
Hidden sources of dietary sugar, which can reduce enjoyment of fruits.
