Colorectal cancer is a type of cancer that affects the large intestine and the rectum. It happens when some cells in those parts of the body start to grow in a way that’s not normal. This can make a person feel sick and weak. Doctors can help by giving treatments like medicine or surgery to remove the unhealthy cells. It’s important to eat healthy foods and exercise regularly to help keep our bodies strong and reduce the chances of getting colorectal cancer.
