If you experience any symptoms of colon or rectal cancer, your physician may perform a blood test, endoscopic procedure (most often, a colonoscopy), biopsy or imaging exam to confirm a diagnosis. If you are diagnosed, your team will determine the specific type and stage of the cancer and develop a treatment plan.
Recognizing Symptoms of Colon and Rectal Cancer
Colorectal cancer rarely causes noticeable symptoms in its earliest stages. As the disease progresses, there may be symptoms. Colon and rectal cancers share similar symptoms. Some are obvious, while others are more subtle.
See your doctor if you experience any new, persistent or unexplained symptoms such as:
- Abdominal pain, gas or cramping
- Bleeding of the rectum
- Bloating or a feeling of being full
- Blood in the stool (black, dark or red color stools)
- Changes in bowel habits or the texture of the stool (constipation or diarrhea)
- Feeling weak or tired
- Nausea or vomiting
- Unexplained weight loss
Any of these symptoms may instead be caused by something other than cancer. The only way to know for sure what is causing a particular symptom is to see your physician.
Monitor Your Symptoms at Home
You know your body — what is normal and what is not. It is important to stay vigilant about any ongoing, recurring or worsening symptoms. Consulting your physician when symptoms begin or worsen can lead to an earlier diagnosis and better outcomes.
Keep a record of your symptoms, how often they occur and if they are getting better or worse with time. If something feels “off” or a change from your normal experience, schedule an appointment with your health care provider as soon as possible.
