Cancer is the uncontrolled division of cells that cause the growth of tumors. Cancerous or malignant tumors metastasize or spread to and damage vital organs. Colon cancer starts in the colon or large intestine and can be of many types, depending on the cells that turn cancerous and where the tumors form. The most common type is adenocarcinomas, which begin in the mucus layer of the colon.

In the early stages of colon cancer, the symptoms can be mistaken for those of other diseases. That said, let’s look at a few telltale signs of colon cancer that one should keep an eye out for:

1. Bowel problems
Constipation and diarrhea affect almost everyone due to minor infections. That said, bowel changes that last for over a few days could indicate a severe health issue and need immediate medical attention. Bloody, narrow, and thin stools can be indicative of changes in the colon. Additionally, large tumors block the colon and can cause disturbances in bowel movement. If there is no known cause and this symptom persists for more than a few weeks, an underlying disease like colon cancer may be responsible. So, it’s best to consult a doctor for an accurate diagnosis and guidance on the next steps.

2. Cramps and bloating
Constant bloating and unexplained cramps could be signs of colon cancer. At the same time, these are common digestive issues that can also occur due to an upset stomach, gas, or a food allergy. If cancer causes a blockage, one might feel that they cannot fully empty their bowel, even after multiple bathroom visits. Constantly needing to use the restroom is another typical telltale sign of colon cancer.

3. Unexplained weight loss
Sudden and unexplained weight loss is a typical sign of almost all forms of cancer, and losing more than 10 pounds in half a year is a worrying sign. Cancer-related weight loss results from the cancer cells consuming a lot of the body’s energy. The immune system also works overtime to fight the disease in cancer patients, also consuming energy and contributing to weight loss.

4. Fatigue
With cancer cells using extra energy and the stress of irregular bowel symptoms, fatigue and weakness become telltale signs of colon cancer. These symptoms can also be side-effects of chronic bloody stools and the resultant anemia. Excess loss of blood can also cause iron deficiency, which triggers irritable bowel syndrome. This condition shares symptoms with colon cancer, and shortness of breath or breathlessness is among the other common symptoms of this disease.

As colon cancer progresses, the chances of successful treatment and survival reduce, which is why early detection is vital. One should visit a doctor without fail if they notice a combination of symptoms for an extended period.
