Rectal cancer is a cancer that occurs in the rectum, the last part of the large intestine. Due to changing dietary patterns, the rate of this disease is increasing all over the world and in young people. The main reasons behind this disease, which can be completely cured if detected early, are:
Unhealthy diet and lack of fiber: Excessive consumption of red meat (beef, pork, mutton), grilled and fried meats, and processed foods (burgers, sausages, bacon) is the main culprit. Along with this, not eating fiber-rich foods such as fruits and vegetables destroys the health of the colon and increases the risk of cancer.
Colorectal Polyps: Small cell growths that occur in the lining of the colon or rectum are called ‘polyps’. These are not cancerous (benign) in the beginning. However, if these remain in the intestines for many years, they can turn into cancer cells over time.
Chronic intestinal diseases (Inflammatory Bowel Disease): People with diseases such as Ulcerative Colitis and Crohn’s Disease, which cause inflammation and ulcers in the intestines for a long time, are at a much higher risk of developing rectal cancer than others due to continuous damage to the intestinal cells.
Obesity and physical inactivity: A sedentary lifestyle, lack of exercise, and excessive weight gain affect the body’s metabolic processes and create a favorable environment for the growth of cancer cells.
Genetics & Age: If someone in the family has had colon/rectal cancer, the next generation is also likely to get it. Genetic mutations such as Lynch Syndrome and FAP may be the cause. In addition, this disease is more common in people over the age of 50, but it is now also common in younger people.
