Colorectal cancer does not occur overnight. First, polyps appear in the lower six inches of the colon ( the rectum ). These polyps are precancerous growths that appear as bumps or abscesses. Sometimes they’re benign, but other times they mutate into cancer, which begins working its way thru the rectal wall, into surrounding lymph nodes and into other organ tissue, wreaking all sorts of havoc. While living a healthy lifestyle helps prevent cancer in general, the sole way to effectively combat colon cancer is to get screened constantly after fifty years of age.

Symptoms of colorectal cancer 
Colorectal cancer is usually unnoticed in its early stages of growth. The following symptoms may indicate cancer colorectal.
* Changes in fecal habits alternating between constipation and diarrhea.
* Blood in the stool.
* A permanent discomfort in the stomach: cramps, gas or pain.
* The feeling that the bowel does not empty completely or having constant desire to defecate.
* A large fatigue.
* An unexplained weight loss.
Note. The presence of blood in the stool may be another explanation, such as hemorrhoids or anal fissure. In addition, some foods can color the stool. This is the case of beets and red licorice.
People at risk
* Age. The disease mainly affects people over 50 years (90% of cases). [click to continue…]
