Here are common factors that increase the risk of colon (colorectal) cancer, explained clearly and safely:
🧬 Non-modifiable risk factors (you can’t change these)
- Age – Risk increases after about age 45–50
- Family history – Having a close relative with colon cancer or polyps
- Genetic conditions – Such as Lynch syndrome or familial adenomatous polyposis (FAP)
- Personal history – Previous colon polyps or colorectal cancer
- Inflammatory bowel disease (IBD) – Long-term ulcerative colitis or Crohn’s disease
🥗 Lifestyle-related risk factors
- Diet high in red or processed meats
- Low fiber intake (not eating enough fruits, vegetables, whole grains)
- Physical inactivity
- Obesity
- Smoking
- Heavy alcohol use
🩺 Medical and environmental factors
- Type 2 diabetes
- Radiation therapy to the abdomen (especially at a young age)
✅ Important to know
Having one or more risk factors does not mean someone will get colon cancer. Many people with risk factors never do, and some people without obvious risk factors still can. Regular screening and healthy habits greatly reduce risk.
If this is for a school project, study notes, or because you’re worried about a specific symptom or family history, let me know and I can tailor it to that.
