Early cases can begin as noncancerous polyps. These often have no symptoms but can be detected by screening. For this reason, doctors recommend screenings for those at high risk or over the age of 50.
Symptoms may vary depending on the cancer’s size and location, but often include alterations in bowel habits. Treatments include surgery, chemotherapy, and radiation.
1Blood in Stools
If you find blood on, or mixed in with your stools, then this could be sign that you have bowel cancer. The blood may be dark, or bright red, and mixed with mucus. Once you see your doctor, they will send off a stool sample for a laboratory analysis called a fecal occult blood test.
