Step 1
Watch for a change in bowel habits. This includes diarrhea, constipation, a feeling that your bowels are not completely evacuated after a bowel movement and having stools that are more narrow than usual.
-
Step 2
Look for blood in the stool. The blood can be either bright red or black and tarry (melena). It is important to note that colon cancer is not the only health problem that might cause blood in your stool. Only a doctor can determine the cause of its existence.

Step 3
Recognize unusual abdominal symptoms such as pain, gas or cramping. Be aware that under normal circumstances, early cancer is not associated with pain. This means it is extremely important to not wait until you are feeling pain to see a doctor.
-
Step 4
Watch for a feeling of fullness or of being bloated. While it is normal to experience fullness after eating a large meal or drinking an excessive amount of fluids, feeling full or bloated without cause is not normal and should be investigated.
-
Step 5
Be aware of unexplained loss of appetite or weight loss. While many of us would rejoice at the thought of losing weight, unexplained loss of appetite and weight loss may be a warning sign of colon cancer and should not be ignored.
-
Step 6
Be conscious of feeling fatigued. Fatigue is different from being sleepy. It is a general feeling of tiredness and lack of energy that, if prolonged, may be cause for alarm.
-
Step 7
Watch for nausea and vomiting. These can not only be early warning signs of colon cancer, but can also lead to other complications, such as dehydration and electrolyte imbalance.
