Colon cancer is the third most common cancer diagnosed in the US and is increasingly affecting younger people. The symptoms of colon cancer include abdominal pain, blood in the stool, changes in bowel habits, fatigue, and unintentional weight loss. While colon cancer may not cause any pain, it can lead to abdominal cramps, a feeling of fullness, and colon spasms. These spasms occur due to issues with the muscles lining the colon, which contract and expand to move food and waste through the gut. If you are experiencing any of these symptoms, it is important to consult a healthcare professional for an accurate diagnosis.
| Characteristics | Values |
|---|---|
| Pain | Colon cancer may not cause any pain. However, depending on where a tumor is located, it can also cause an obstruction, or a blockage in the colon, which can cause severe pain. |
| Muscle Pain | Colon cancer can cause muscle spasms. Anticramping medications may help people with colon spasms by relaxing the intestinal muscles to relieve pain. |
| Symptoms | Blood in the stool, abdominal pain, fatigue, lack of appetite, unintentional weight loss, changes in bowel habits, abdominal cramps, a feeling of fullness, and bloating. |

What You'll Learn
Colon cancer may not cause any pain
Colon cancer typically develops from polyps or growths in the inner lining of the colon, which can become cancerous over time. If left untreated, the cancer can spread through the layers of the colon, eventually reaching the muscle wall. At this stage, colon cancer may cause pain and tenderness in the lower abdomen. However, it is important to note that pain is not always present, even in advanced stages of colon cancer.
In some cases, colon cancer may cause an obstruction or blockage in the colon, leading to severe pain. This pain is typically felt on the lower left side of the abdomen. However, not all blockages cause pain, and some people may only experience mild discomfort or occasional cramps.
It is worth mentioning that colon spasms, which can cause abdominal cramps or a feeling of fullness, are rarely a sign of colon cancer. Other possible causes of colon spasms include irritable bowel syndrome (IBS), stress, and bowel endometriosis. Therefore, the presence of abdominal cramps does not necessarily indicate colon cancer.
While colon cancer may not always cause pain, it is important to be vigilant and consult a doctor if you experience any potential symptoms. Early detection and diagnosis can significantly improve treatment outcomes and life expectancy.

Tumours can cause inflammation, leading to pain and discomfort
Colon cancer may not cause any pain, but some patients experience abdominal cramps or a feeling of fullness. The muscles lining a healthy colon contract and expand to move food and waste through the gut. However, if a health problem causes issues with how these muscles work, a person might experience colon spasms.
Colon cancer develops from certain polyps or growths in the inner lining of the colon. If left untreated, the cancer works its way through a layer of tissue, muscle, and the outer layer of the colon. Tumours can cause inflammation, leading to pain and discomfort. Inflammation is closely associated with all stages of development and malignant progression in most types of cancer. It can either promote or suppress tumour progression, potentially displaying opposing effects on therapeutic outcomes. Chronic inflammation facilitates tumour progression and treatment resistance, while acute inflammatory reactions often stimulate the maturation of dendritic cells and antigen presentation, leading to anti-tumour immune responses.
Inflammatory cells have powerful effects on tumour development. They produce an attractive environment for tumour growth, facilitate genomic instability, and promote angiogenesis. The inflammatory cells and the chemokines and cytokines they produce influence the entire tumour organ, regulating the growth, migration, and differentiation of all cell types in the tumour microenvironment. Later in the tumourigenic process, neoplastic cells also divert inflammatory mechanisms to favour neoplastic spread and metastasis.
Tumour cells can also regulate their chemokine expression to help recruit inflammatory cells and further tumour growth and progression. Melanoma is an example of this, where blocking or attenuating specific chemokines or receptors has been shown to reduce tumour cell proliferation.

Colon spasms may be a sign of cancer
Colon cancer usually doesn't cause symptoms in its early stages. However, as the disease progresses, symptoms such as abdominal pain, rectal bleeding, and changes in the size and shape of stools may occur. Other symptoms of colon cancer include unintentional weight loss, iron deficiency anemia, jaundice, and a persistent feeling of needing to have a bowel movement.
If colon cancer spreads to other areas of the body, it can cause local and systemic symptoms. Local symptoms are based on the location of the tumor and can include a blockage in the colon, leading to severe pain on the lower left side of the abdomen. Systemic symptoms involve the whole body and can include fatigue and weight loss.
It's important to note that colon cancer pain is not always present, and even in cases of advanced colon cancer, only about 15% of patients report pain as a symptom. However, abdominal pain or discomfort that doesn't go away or is unusually frequent should be evaluated by a doctor.
If you are experiencing colon spasms along with other red-flag symptoms, it is crucial to consult a healthcare professional for a proper diagnosis.

Obstruction or blockage in the colon can cause severe pain
Colon cancer is a serious but treatable condition that develops from polyps or growths in the inner lining of the colon. It is the third most common cancer diagnosed in the U.S. and is increasingly affecting younger people. The recommended age for people's first colon cancer screening with a colonoscopy has recently been lowered from 50 to 45.
Colon cancer may not cause any pain, and most patients do not report pain as a symptom. However, when they do, patients describe the pain as an intermittent, crampy feeling in their abdomen. Pain caused by colon cancer can also be described as a feeling of fullness or bloating in the upper right side of the abdomen.
Colon cancer can cause a blockage in the colon, which can lead to severe pain. This is known as a bowel obstruction, which can be partial or complete and occurs when something blocks the small or large intestine. Other symptoms of a bowel obstruction include persistent vomiting, abdominal cramping, dehydration, and an inability to pass stool or gas.
If you suspect a bowel obstruction, it is important to seek immediate medical attention. Abdominal X-rays, CT scans, and barium enema X-rays can help diagnose a bowel obstruction and determine its location and cause. Treatment options may include intestinal content removal using a small, flexible tube, intravenous fluids, electrolyte replacement, pain medication, or, in some cases, surgery.

Other symptoms include fatigue, lack of appetite and weight loss
Colon cancer is the third most commonly diagnosed cancer among men and women. It is important to be aware of the symptoms of colon cancer, especially as many patients do not experience any pain. The recommended age for people's first colon cancer screening has been lowered from 50 to 45, but those with a family history of colon cancer should consider starting screenings earlier.
Fatigue, lack of appetite, and weight loss are all symptoms associated with colon cancer. Unintentional body weight loss (BWL) is defined as the loss of more than 5% of body weight within the last 6–12 months, or defined by a change in clothing size and the reported weight loss by a family member or friend. BWL is a common symptom of malignant diseases, particularly those of the digestive system, and is correlated with tumor location, size, and depth. It is also a prognostic factor for poor outcomes, including overall survival and tumor relapse.
In addition to weight loss, changes in bowel habits are a common symptom of colon cancer. This can include diarrhea, which can also lead to weight loss. Other symptoms include blood in the stool, which can range from dark to bright red, and abdominal pain, such as intermittent cramping. However, many patients with colon cancer do not experience pain and instead report an odd sensation of fullness or bloating in their abdomen.
If you are experiencing any of these symptoms, it is important to see your doctor and take your symptoms seriously. Even if you have not had any symptoms, it is a good idea to get a check-up and be proactive in caring for your digestive health.
