You notice blood in your stool and assume it is piles. Or perhaps your bowel habits have changed, you feel unusually tired, and you’ve started losing weight without trying. It is easy to dismiss these symptoms, especially when they are not painful.
But persistent changes in bowel habits should not be brushed aside. Colon cancer can sometimes develop quietly, which is why timely evaluation matters.
A colon cancer surgeon is involved when tests suggest a tumour or cancer affecting the colon and surgery may be part of treatment.
You may be advised to consult one after a colonoscopy, biopsy, CT scan, or other investigation identifies an abnormal growth. Surgical evaluation may also be recommended when a gastroenterologist or oncologist believes that removing the affected section of the colon could be necessary.
Blood in the stool is one of the symptoms people commonly ignore. While it can have several causes, recurring bleeding should always be investigated.
Other warning signs include a persistent change in bowel habits, constipation or diarrhoea that does not settle, unexplained weight loss, ongoing abdominal discomfort, unusual weakness, or a feeling that the bowel has not completely emptied.
Having these symptoms does not mean you have cancer. They simply mean that finding the actual cause is important.
Treatment for colon cancer is not identical for every patient. The location and size of the tumour, whether nearby lymph nodes are involved, and the overall stage of the disease can influence treatment planning.
A colon cancer surgeon evaluates whether surgery is appropriate and, when required, plans the removal of the affected portion of the colon along with nearby tissues or lymph nodes as appropriate.
In selected cases, minimally invasive surgery may be considered. The exact technique depends on the patient's condition and the surgeon's assessment.
One mistake we regularly see is patients waiting because their symptoms are manageable.
A patient may say, “There’s only a little blood,” or “My constipation has been happening for months, but it isn't painful.” Unfortunately, the seriousness of a digestive problem cannot always be judged by how uncomfortable it feels.
Consider a patient who initially assumed occasional blood in the stool was caused by piles. When the bleeding continued, further evaluation was performed and a colon abnormality was identified. Early specialist involvement allowed the treatment team to assess the condition properly and plan the next steps rather than continuing to treat the symptom alone.
The important takeaway is simple: don't diagnose persistent symptoms yourself. Get the cause checked.
When looking for a colon cancer surgeon, focus on experience with colorectal conditions, communication, surgical options, and coordination with other specialists.
Cancer care often involves more than one professional. A surgeon may work alongside gastroenterologists, medical oncologists, radiation specialists, pathologists, and radiologists to create a treatment plan based on the patient's individual findings.
We always recommend asking questions during the consultation: What exactly has the test shown? Is surgery necessary? What alternatives exist? What will recovery involve? Are additional treatments likely to be needed?
Some people believe that surgery should be avoided for as long as possible because it is “too aggressive.”
That isn't a useful rule.
When cancer is confirmed and surgery is medically appropriate, delaying treatment simply because surgery sounds frightening may not be beneficial. At the same time, surgery should not be recommended without proper evaluation. The right decision depends on the diagnosis, stage, overall health, and treatment plan.
Common warning signs can include blood in the stool, persistent changes in bowel habits, unexplained weight loss, abdominal discomfort, and unusual fatigue. These symptoms can also have non-cancerous causes.
You may be referred to a colon cancer surgeon when investigations identify colon cancer or another condition that may require surgical treatment.
Treatment depends on the type and stage of the cancer. Some patients may need surgery, chemotherapy, radiation, targeted treatment, or a combination of approaches.
If you have ongoing bowel changes, unexplained bleeding, weight loss, or have already received an abnormal colonoscopy or biopsy result, don't keep guessing about the cause.
Book a consultation with a qualified specialist, carry your previous reports, and get a clear understanding of your diagnosis and treatment options before making your next decision.
