Colorectal cancer is no longer solely a disease of the elderly. The trend of this condition affecting younger individuals is increasing globally, with a primary cause stemming from daily habits we often overlook.
The American Cancer Society confirms that early-onset cases are rising in over half the countries worldwide. Consistent research indicates that diet and lifestyle play a crucial role in this trend.
Recently, Doctor Karen Zaghiyan, a colorectal surgeon in Los Angeles, US, identified five specific things she absolutely avoids to protect her digestive system.
Processed meats
Topping the list of risky foods are processed meats such as bacon, pepperoni, and deli meats. Numerous studies have demonstrated a link between this food group and colorectal cancer risk, with an estimated increase of 13-22%.
According to the American Institute for Cancer Research, consuming just 50 g of processed meat daily (equivalent to about two slices of bacon) increases the risk of the disease by 16%.

Charred grilled meats
Meat cooked directly over a flame, especially when charred or blackened, poses another danger. High-temperature grilling produces chemical compounds called HCAs and PAHs.
Laboratory studies indicate these substances can cause tumors, including in the colon. The charred parts of the meat are the clearest sign of these carcinogenic compounds.
Overusing antibiotics for mild illnesses
Doctor Zaghiyan warns against using antibiotics too frequently for mild infections or common colds.
Research suggests that continuous antibiotic use for two months or longer in adulthood can significantly increase the likelihood of developing precancerous tumors later. This is attributed to prolonged disruption of the gut microbiome.
Ultra-processed foods
This group includes packaged snacks, industrial pastries, sugary drinks, and instant meals. They are characterized by significant structural alteration and very low fiber content.
A large study in 2025 found that women under 50 who consumed the most ultra-processed foods had up to a 45% higher risk of developing precancerous polyps.
Alcohol-based mouthwash
Few would suspect mouthwash to be linked to the colon. However, a recent study showed that daily use of alcohol-based mouthwash for three months significantly altered the oral microbiome, increasing bacteria associated with gum disease and colorectal cancer. For this reason, Doctor Zaghiyan has included alcohol-based mouthwash on her list of products to absolutely avoid.
Colorectal cancer often progresses silently, but the body always provides warning signs that should not be ignored:
Persistent changes in bowel habits.
Blood in the stool.
Persistent abdominal discomfort or dull pain.
Unexplained weight loss.
Persistent fatigue or a feeling of incomplete bowel emptying.
Recognizing symptoms early and making lifestyle changes today can significantly improve treatment outcomes and protect your future health.
