Symptoms of Colorectal Cancer
The earliest stages of colorectal cancer have no symptoms. Colorectal tumors can grow slowly over the course of several years. This can cause subtle symptoms that only appear at later stages. If you have any of these symptoms, do not assume it is due to cancer. Symptoms can be caused by other, less serious conditions. However, it is still important to discuss them with your doctor. Early detection and treatment improve outcomes for cancer and other health issues.
