Colorectal Cancer Symptoms  

Colorectal cancer can take several years in your body before producing symptoms. The tumor rise asymptomatically from polyps in the lining of the large intestine without impairing your normal life; this does not prevent it from progressively damaging the colorectal tissues. When symptoms finally occur, the disease is often advanced and therefore more difficult to be treated.  

In general, if you have colorectal cancer, you will experience at least one of these symptoms: 

• vomiting 
• anemia associated with fatigue 
• blood in the stool  
• unexplained weight loss 
• constant urge to defecate 
• feeling that your bowel does not completely empty   
• permanent discomfort characterized by stomach cramps, gas or pain 
• persistent change in bowel movements characterized by alternation between constipation and diarrhea.

However, the presence of blood in your stool does not automatically mean you have bowel cancer. Certain conditions such as hemorrhoids or anal fissure can cause rectal bleeding (hematochezia). In addition, certain foods such as beets and red licorice can make your stools appear reddish.
