10 Warning Signs of Colon Cancer You Shouldn’t Ignore

Medical professionals often refer to colorectal cancer, which includes colon cancer that affects the large intestine and rectal cancer that affects the lowermost part of the large intestine.

According to the American Cancer Society, 1 in 20 people is at a risk of developing colorectal cancer during their lifetime.

The exact cause of colorectal or bowel cancer is not known. However, it is believed to develop when healthy cells become abnormal and start growing in number and accumulate in the lining of the colon, forming polyps. Left untreated, polyps may become cancerous.

Several factors increase your risk of developing colon and rectal cancer, including aging (above 50 years), some types of bowel diseases, family history, obesity, smoking, excessive alcohol intake, a sedentary lifestyle, Type 2 diabetes and regular intake of processed foods or red meats.

African-Americans are at a greater risk of colon cancer than people of other races.

As it can be difficult to treat colon cancer after it spreads to nearby areas, it is important to know what the early symptoms are. This can help you seek early treatment and give you a better chance in recovery.

Here are the top 10 warning signs of colon cancer you shouldn’t ignore.

1. Constipation

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.

2. Diarrhea

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.
