A new study has found a significant shift in rectal cancer patterns across different generations of Americans. Researchers have discovered that those born in 1990 are four times more likely to develop rectal cancer compared to those born in 1950.
The study also shows a sharp rise in gastrointestinal cancers among people under 50, with cases surging by 15% over the past decade. The findings suggest that most of these cancers are linked to obesity and diets dominated by processed foods, rather than genetic defects.
According to Dr. Elber Camacho, Medical Director at Desert Regional Comprehensive Cancer Center, excessive consumption of processed foods leads to inflammation in the gastrointestinal tract, increasing the risk of cancer development. This alarming trend is hitting minority groups hardest.
The study’s publication in the “British Journal of Surgery” highlights the growing concern about rectal and gastrointestinal cancers, particularly among young adults.
