Colorectal cancer is a serious health issue that can arise from a combination of lifestyle, environmental factors, and inherited genetic characteristics. The main factors that increase the risk of developing this type of cancer are:

Genetic Factors:
A family history of colorectal cancer significantly increases an individual's risk. Although inherited genetic mutations account for only a small percentage of cases (5-10%), cancer tends to appear at younger ages in these individuals and can often be more aggressive.

Age:
The risk of colorectal cancer increases with age, with the vast majority of cases occurring in individuals over 50. Specifically, the likelihood of developing colon and rectal cancer is ten times higher in individuals over 60 compared to those under 40.

Inflammatory Bowel Diseases (IBD):
Chronic inflammatory bowel diseases such as ulcerative colitis and Crohn's disease increase the risk of developing colon cancer. These conditions cause long-term inflammation in the bowel lining, raising the potential for cells to become cancerous.

Diet:
A diet poor in fiber can lead to constipation, causing stool to remain in the intestine for longer periods and increasing exposure to potential carcinogens. Excessive consumption of processed meats (delicatessen products, cured meats, smoked meats) and fried foods are also among the dietary habits that elevate risk.

Obesity:
In both women and men, excessive weight or obesity significantly increases the risk of colorectal cancer.

Smoking:
Numerous studies have shown a direct link between smoking and the development of colorectal cancer.
