Colon cancer is one of the most common cancers in the world. It presents with tumorous growths in the large intestine. The large intestine is responsible for drawing out water and salt from food waste. After that, the waste material hardens and is transported out as feces, through the rectum and the anus.

Colon cancer is more common in people age 50 years and older. Colon cancer can also develop along with rectal cancer; the combined condition going by the name colorectal cancer. The -rectal refers to the rectum, which is located at the end of the digestive system, while the colo- refers to the large intestine or colon. Colorectal cancer is worse than colon cancer alone.

1. Symptoms of Colon Cancer

Colon cancer does not show any kind of symptoms in its earliest stages, but starts showing symptoms after it has progressed significantly. The earliest symptoms of colon cancer include diarrhea or constipation, changes in the consistency of stool, and defecating loose, narrow stools. After a while, the patient may have blood in the stools. The blood in stool may not be visible at the start, but after a while, the patient complains about it. Another common symptom of colon cancer is an urge to defecate followed by incomplete bowel evacuation. Abdominal pain, cramps, and excess gas are additional symptoms as the disease progresses. Symptoms in later stages include general weakness and fatigue, significant loss of weight, and iron deficiency anemia.
