Colon cancer

Causes of colon cancer

Doctors aren’t sure what causes most colon cancers. In general, colorectal colon cancer begins when healthy cells in the colon develop changes or mutations in their DNA. Healthy cells grow and divide in an orderly way so your body continues to function normally. But when a cell’s DNA is damaged and becomes cancerous, cells continue to divide even when new cells are not needed. As the cells accumulate, they form a tumor.

Factors that can increase your risk of colon cancer include:

● Older age. Colon cancer can be diagnosed at any age, but most people with colon cancer are over the age of 50; however, doctors don’t know why, but colon cancer rates in people under 50 have been on the rise.
● Black ethnicity. Black people have a higher risk of colon cancer than people of other races.
● Personal history of colorectal cancer or polyps. If you have already had colon cancer or non-cancerous colon polyps, you are at increased risk of colorectal colon cancer in the future.
● Inflammatory bowel conditions. Chronic inflammatory diseases of the intestinal area, such as ulcerative colitis and Crohn’s disease, can increase the risk of colon cancer.
● Family history of colon cancer. You are more likely to develop colon cancer if you have a blood relative who has had the disease, and if more than one family member has had colon cancer, your risk is even higher.
● Diet low in fiber and rich in fat. Colorectal cancer may be associated with a typical high-fat diet that is low in fiber. There is an increased risk of colon cancer in people who eat diets rich in red meat and processed meat.
● An inactive lifestyle. Inactive people are more likely to develop colon cancer. Getting regular physical activity can reduce the risk of colon cancer.
●Diabetes. People with diabetes or insulin resistance are at increased risk of cancer.
● Obesity. Obese people have a higher risk of dying from colon cancer compared to people who are considered normal weight.
● Smoking. People who smoke may have an increased risk of colon (colorectal) cancer.
●Alcohol. Excessive alcohol consumption increases the risk of colon cancer.
● Radiation therapy for cancer. Radiation therapy to the abdomen to treat previous cancers increases the risk of colon cancer.
