Colon cancer is a type of cancer that originates in the large intestine (the colon) or the rectum. As these two are significant parts of the lower portion of the digestive system, their damage may substantially impact the body’s functioning. Nearly 101,000 new colon cancer cases are reported annually, making it one of the country’s leading causes of cancer deaths. Take a look at some of the early symptoms of colon cancer below. 

Causes of colon Cancer
There are no definite causes of colon cancer. Still, research has found that genetic mutations play a significant role in the development of colon cancer, even though they do not guarantee it. Some genetic mutations may cause the formation of abnormal cells called polyps in the colon lining that are benign. But if left untreated, they may become cancerous in the future. 

Early signs
Suppose there is a medical history of colon cancer in the family. In that case, it is advised to get regular checkups done to spot the cancer cells as early as possible and begin the necessary therapy. Unlike other illnesses, colon cancer does not show signs in its early stages. Take a look at a few of the early signs below. 

Rectal bleeding
Bleeding of the rectum is one of the most common signs of colon cancer. It is caused due to damaged healthy cells in the affected area; the color can range from bright to dark red. 

Changes in bowel habits
A significant change in the bowel habits, such as narrowing of the stool, constipation, and diarrhea, which lasts for more than a few days and does not respond to home remedies, can be one of the first symptoms to show up in case of colon cancer. 

Abdominal pain
One should not ignore persistent pain in the abdomen; if this stays on for more than a couple of days, it is advised to visit a healthcare professional, find the reason, and go in for therapy. 

Blood in stool
Colon cancers can often cause bleeding in the digestive tract, due to which blood can be spotted in the stool, causing it to look dark brown or black. This regular blood loss can also lead to other problems, such as anemia. 

Symptoms of colon cancer
There might be no significant symptoms of colon cancer, especially in the earlier stages of the condition, but this does not mean that the existing ones be ignored. As cancer grows and the illness reaches stage 2 or 3, it might show a few symptoms like the ones below.

Excessive gas
Under normal circumstances, gas can cause immense pain in the stomach and the abdomen and may pass away after a while. But if this does not happen, one must consult a healthcare professional to determine the underlying cause. 

Changes in stool shape
It might go unnoticed at first, but changes in the shape, including narrowing of the stool, are crucial symptoms of colon cancer. If other early signs of the disease accompany it, it is advised to inform the therapist immediately.
