Ontario has one of the highest rates of colorectal cancer in the world. Colorectal cancer, also known as colon cancer, is a major cause of morbidity and mortality throughout the world. It accounts for over 9% of all cancer incidence and it is the third most common cancer worldwide and the fourth most common cause of death. It affects men and women almost equally.
Colorectal cancer affects either the colon or rectum, or both. During the early stages of colorectal cancer when it is most treatable, there are often no signs or symptoms. This reinforces the importance of participating in regular screening even when you are symptom-free. Signs and symptoms often begin to appear once a tumour grows into neighbouring tissues and organs and will vary based on the tumour size and location in the colon or rectum.
Inform your doctor as soon as possible if you notice these early signs of warnings: Unexplained changes in bowel habits, such as constipation or diarrhea; change in size/shape of stools, such as being narrower than usual; the urge to have a bowel movement but nothing passes; rectal bleeding; blood in or on the stool, ranging from bright red to dark black; persistent abdominal pain/discomfort including bloating, fullness, cramps, gas pain; unexplained weight loss; weakness and fatigue; anemia, caused by iron deficiency.
