Here are the top 3 warning signs of colon cancer you shouldn’t ignore.
Constipation is an important sign of cancer in the colon. A 2011 study published in the Asian Pacific Journal of Cancer Prevention highlights the link between constipation and colorectal cancer risk.
An earlier 2004 study published in the European Journal of Cancer supported the hypothesis that constipation or laxative use increases the risk of colon cancer.
A tumor present at the far end of the colon can make it very difficult to eliminate waste products, thereby causing constipation.
If you persistently have fewer bowel movements per week, without any prior problem of constipation, consult your doctor to find out the exact cause.
If you suffer from diarrhea for more than a couple of weeks, it may be an early symptom of colon cancer.
When a tumor partially obstructs the bowel, it can cause alternating constipation and diarrhea due to leakage of liquid stool.
You may also experience frequent gas, abdominal pain, nausea and vomiting. Plus, a tumor may irritate or narrow the lining of the intestine.
It is important to consult your doctor when you have diarrhea that lasts more than a few days, as it can lead to dehydration, drain your body of nutrients and signal other serious problems, such as cancer.
3. Blood in Stools
Most often, blood in the stool is due to piles (hemorrhoids), where the veins in the back passage become fragile and cause a little bleeding during a bowel movement. This type of bleeding is generally red.
However, if you notice dark red or black blood in your stool, it can be a sign of cancer, such as bowel, rectal or colon cancer. It can also be due to a stomach ulcer.
Whether bleeding is due to piles, a stomach ulcer or cancer, it’s important to get it checked by a doctor. Proper diagnosis is essential for appropriate treatment.
