Cancer affecting the colon, the last part of the digestive system, is on the rise worldwide. If detected early, it is completely treatable. The main causes that lead to this are:
Low-fiber diet: Consumption of over-processed foods and flour products affects the health of the colon. A decrease in fiber, which includes fruits and vegetables, causes constipation and the retention of toxins in the intestines.

Excessive consumption of red meat: Excessive consumption of red meats like beef and mutton, and processed meats like sausages, can cause changes in the cells of the colon. Studies indicate that this increases the risk of cancer.
Obesity and lack of exercise: Weight gain and decreased physical activity are directly linked to colon cancer. Exercise helps to move the bowels and speeds up the digestive process.
Smoking and alcohol: Smoking can cause the formation of small tumors (polyps) in the colon, which can later turn into cancer. Similarly, excessive alcohol consumption damages the cells in the colon.

Heredity and age: If someone in the family has had colon cancer, the risk of developing it is higher. Also, this disease is usually more common in people over the age of 50.
