From constipation to feeling 'full' too soon: Top doctor warns against 6 colon cancer red flags

Early warning signs of colon cancer are often overlooked or mistaken for minor diseases and everyday gastro issues. But many of these symptoms appear in young and active individuals who seem healthy, making them easy to dismiss. Dr. Vivian Asamoah, who has worked with hundreds of colon cancer patients over the span of 15 years, emphasises key symptoms everyone should know. Recognising these early signs and acting promptly can save lives and help prevent serious complications.

Constipation and diarrhea

Dr. Asamoah emphasizes that the presence of constipation or diarrhea that feels abnormal should serve as an initial warning sign. While it is true that everyone's digestive patterns may fluctuate occasionally, if bowel habits begin to change consistently or feel unusual, it is essential to pay attention to what our body is trying to communicate. This could potentially indicate that the colon is confronting an issue that is more significant than just a simple stomach virus or a minor modification in diet. Therefore, if the symptoms of constipation or diarrhea persist without any clear reason or cause, it is advisable to consult with your healthcare provider.

Pencil-thin stool

Another warning sign to watch out for is pencil-thin stool or one that is unusually narrow and does not seem to return to its original shape. This can happen if there is narrowing in the colon caused by a tumour or growth. This change is often gradual and easy to overlook, but it is important to not ignore it. If your stools are consistently thin and ribbon like, it is a signal that something may be wrong and should be checked by a doctor as soon as possible.

Unexplained weight loss

Unexplained weight loss is another warning sign to pay close attention to. Losing weight without even trying seems like a great thing, but if there is no apparent reason, like any changes in diet or exercise, it can be a big red flag. This could purposely happen if the cancer cells are affecting the metabolism or appetite or the body may be dealing with inflammation or an infection early on. Even if you feel fine otherwise, sudden or unplanned weight loss should always be checked by a doctor.

Fatigue

• Dr. Asamoah highlights that persistent fatigue, even with adequate sleep, is a symptom often overlooked and warrants attention.
• Feelings of exhaustion that do not improve with rest may indicate serious health issues, such as anemia from slow internal bleeding or chronic illness reactions.
• A thorough medical evaluation is crucial for fatigue that remains unchanged despite sufficient sleep.

Blood in stool

• Blood in the toilet or on toilet paper is a serious symptom that should not be overlooked.
• Bleeding during elimination may indicate conditions ranging from hemorrhoids to more serious issues such as colon cancer.
• Early colon cancer can present with bleeding before other symptoms appear, emphasizing the need for early evaluation and diagnosis.

Feeling full

Finally, there is the feeling of your bowels not being completely emptied. The feeling of incomplete evacuation, or tenesmus, can be painful and ongoing. It can indicate that something is irritating or perhaps blocking the colon, such as a tumor or inflammation. If this feeling persists for more than a week or two, you should seek medical advice.

Dr. Asamoah's insight:

Dr. Asamoah emphasizes that these symptoms do not necessarily point to cancer, but they are signs that one should have checked and probably screened for. She recommends a colonoscopy if you are 45 or older, even without symptoms, because this test is an effective way to detect cancer early and help prevent the disease by removing precancerous polyps.

It is important for individuals below the age of 45 showing these signs not to disregard them because they may consider themselves younger or very healthy. Younger adults are increasingly being diagnosed with colon cancer, making awareness and early medical consultation quite vital. If you are experiencing any of the above mentioned symptoms, and if they are regular, it is best to consult a medical health professional for proper diagnosis.
