1. Age (especially over 50)
The risk of colon cancer rises significantly after the age of 50. However, recent studies show an alarming increase in cases among younger adults, often linked to lifestyle and diet.
2. Family history or genetics
If you have a first-degree relative (parent, sibling, or child) who has had colon cancer or colon polyps, your risk can double or even triple. Certain hereditary conditions also raise the risk dramatically, such as:
Lynch syndrome
Familial adenomatous polyposis (FAP)
These genetic syndromes require early and regular screening.
3. Diet low in fiber and high in processed foods
A diet rich in red meat, processed meats (like bacon or sausages), fast food, and refined carbohydrates has been strongly linked to colon cancer.
Meanwhile, diets lacking:
Fruits
Vegetables
Whole grains
can reduce fiber intake, slowing digestion and increasing inflammation in the colon.
4. Lack of physical activity
Sedentary lifestyles contribute to slower digestion, increased inflammation, and higher body fat — all of which increase colon cancer risk. Regular physical activity can lower risk by improving metabolism and gut health.
5. Obesity and excess body fat
