Some animals' natural biological defenses could inspire new approaches to cancer prevention and treatment in humans

Study examined data from 273 vertebrate species, analyzing diets, average plasma sugar levels and cancer prevalence.

Birds, despite their high blood sugar, have lower cancer rates than mammals and reptiles.

Primary carnivores are more prone to tumors than herbivores, especially when domestication is considered.

Study suggests some species have evolved biological defenses against cancer.

Birds may have evolved unique cancer defenses, potentially related to their high metabolic rate, reliance on fat metabolism over glucose, and cellular adaptations that limit oxidative damage.

Understanding these adaptations could provide valuable insights into how species evolve natural cancer defenses.

For now, the best advice for humans remains consistent with public health recommendations: Eat a balanced diet, avoid excessive processed and red meat, and manage blood sugar through a healthy lifestyle.
