What Is Bowel Cancer?
Bowel cancer, also known as colorectal cancer, is a type of cancer that begins in the large intestine, which includes the colon and the rectum. It typically starts as small, noncancerous clumps of cells called polyps that form on the inside of the colon. Over time, some of these polyps can develop into cancer.
Regular screening can find and remove these polyps before they turn into cancer, making it one of the more preventable forms of the disease. Understanding the warning signs is the first step in being proactive about your health.
Key Warning Signs of Bowel Cancer
The symptoms of bowel cancer can be subtle and may not necessarily make you feel ill. It’s important to be aware of what is normal for you so you can spot any persistent changes. Many of these symptoms can also be caused by other, less serious conditions like hemorrhoids, irritable bowel syndrome (IBS), or inflammatory bowel disease (IBD). However, if you experience one or more of these for three weeks or longer, it is essential to see a doctor.
1. A Persistent Change in Bowel Habits
This is one of the most common signs. It doesn’t refer to a single day of unusual bowel movements, but a persistent change that lasts for several weeks. This can include:
- Diarrhea: Having looser, more watery stools more frequently than what is normal for you.
- Constipation: Struggling to pass stools or going less often than usual.
- Changes in Stool Consistency: Your stools may become narrower than usual, sometimes described as ribbon-like. This can happen if a tumor is partially blocking the intestine.
2. Blood in Your Stool or Rectal Bleeding
Seeing blood in the toilet bowl or on your toilet paper after a bowel movement should always be checked by a doctor. The blood can appear in different ways:
- Bright Red Blood: This often indicates bleeding in the lower part of the colon or rectum. While it can be a symptom of hemorrhoids, you should not assume this is the cause without a proper diagnosis.
- Dark Red or Black Stools: This can be a sign of bleeding higher up in the bowel. The blood appears darker because it has been digested, giving the stool a tar-like appearance.
3. Unexplained Abdominal Pain or Discomfort
Persistent pain, aches, or cramps in your stomach or back passage can be a warning sign. You might also experience a constant feeling of bloating or fullness that doesn’t go away. While many things can cause abdominal discomfort, pain that is new and persistent should be investigated.
4. A Feeling of Incomplete Bowel Evacuation
This symptom is the sensation that you need to have a bowel movement even after you’ve just been to the toilet. It can feel like your bowel is not completely empty. This can be caused by a tumor in the rectum creating a feeling of fullness or obstruction.
5. Unexplained Weight Loss
Losing weight without changing your diet or exercise routine is a significant symptom that should not be ignored. Cancer cells consume a lot of the body’s energy supply. The cancer can also change the way your body processes food, leading to a loss of appetite and unintended weight loss.
6. Weakness or Fatigue
This is more than just feeling tired after a long day. It’s a persistent lack of energy that isn’t relieved by rest. In the context of bowel cancer, fatigue is often caused by anemia, which is a shortage of red blood cells. A tumor in the bowel can bleed slowly over time, leading to iron deficiency anemia, which causes tiredness and sometimes shortness of breath.
Why Early Detection Is Crucial
The ad mentioned that early detection influences treatment, and this cannot be overstated. When bowel cancer is found at its earliest stage, it is highly treatable.
- Better Treatment Outcomes: According to the American Cancer Society, the 5-year relative survival rate for localized bowel cancer (cancer that has not spread outside the colon or rectum) is about 91%. However, if the cancer has spread to distant parts of the body, that rate drops to about 14%. Finding it early makes a life-changing difference.
- Less Invasive Treatment Options: When cancer is detected early, perhaps as a small polyp, it can often be removed completely during a colonoscopy. This is a minimally invasive procedure that can prevent cancer from ever developing. For early-stage cancers, surgery may be simpler and more effective.
- Avoidance of Complex Therapies: Later-stage cancers often require more aggressive and complex treatments, such as extensive surgery, chemotherapy, and radiation therapy. These treatments can have significant side effects and a greater impact on your quality of life. Early detection can help you avoid the need for these more intensive therapies.
When to See a Doctor
If you are experiencing any of the signs mentioned above for more than three weeks, make an appointment with your doctor. It can be easy to dismiss these symptoms, but it is always best to get checked for peace of mind.
Your doctor will likely ask about your symptoms and family history. They may recommend further tests, such as:
- A Fecal Immunochemical Test (FIT): An at-home test that checks for hidden blood in your stool.
- A Colonoscopy: A procedure where a doctor uses a thin, flexible tube with a camera to look at the inside of your entire colon and rectum.
Frequently Asked Questions
What is the difference between bowel cancer and colon cancer? The terms are often used interchangeably. Bowel cancer is a general term for cancer that starts in the large bowel. The large bowel is made up of the colon and the rectum. So, colon cancer is a type of bowel cancer that is specifically located in the colon.
At what age should I start screening for bowel cancer? Screening recommendations can vary by country and individual risk. In the United States, organizations like the American Cancer Society recommend regular screening for people at average risk to start at age 45. If you have a family history of the disease or other risk factors, your doctor may recommend starting earlier.
Can hemorrhoids cause the same symptoms? Yes, hemorrhoids can cause bright red rectal bleeding and discomfort, which are also symptoms of bowel cancer. Because the symptoms can overlap, it is very important not to self-diagnose. Always see a doctor to determine the correct cause of your symptoms.
