Reading on could help you or a loved one act at the right time and protect long-term digestive health.
What Is Colon Cancer?
Colon cancer is a malignant growth that begins in the large intestine, often from small growths called polyps. Over time, certain polyps can turn cancerous.
Many cases start silently, which is why knowing the warning signs matters. Early detection greatly improves survival.
Key facts to understand:
- Starts in the colon or rectum
- Often develops from colon polyps
- Grows slowly over several years
- Highly treatable when found early
- Screening can prevent many cases

1. Change in Bowel Habits
A lasting change in bowel habits is one of the most common colon cancer symptoms. This means new patterns that do not resolve within a few weeks.
You may notice:
- Persistent diarrhoea or constipation
- Narrow, pencil-thin stools
- Increased urgency to go
- Changes lasting over four weeks
2. Blood in Stool or Rectal Bleeding
Blood in the stool is a red flag that should never be ignored. It may appear bright red or make stools look dark and tarry.
While piles or fissures can also cause bleeding, colon cancer must be ruled out.
Watch for these signs:
- Bright red blood on toilet paper
- Dark, tarry-looking stools
- Blood mixed within the stool
- Bleeding without obvious pain
Never ignore rectal bleeding—book an evaluation at Lux Hospitals promptly.
3. Persistent Abdominal Discomfort
Ongoing belly discomfort can signal a problem in the colon. Cramps, bloating, or gas that keep returning deserve attention.
These symptoms may worsen as a tumour grows and narrows the bowel.
Common complaints include:
- Recurring cramps or bloating
- Excess gas and fullness
- Pain that does not ease
- Feeling of blockage in the gut
4. Unexplained Weight Loss
Losing weight without trying can be an early sign of colon cancer. Cancer cells use energy and can affect appetite.
This symptom is often subtle but significant when combined with others.
Be alert if you notice:
- Weight loss without diet changes
- Reduced appetite
- Feeling full quickly
- Muscle wasting over time
5. Fatigue and Weakness
Constant tiredness that rest does not fix can point to colon cancer. Slow, hidden bleeding may lower your blood count.
This fatigue often builds gradually and is easy to dismiss.
Symptoms may include:
- Persistent tiredness despite rest
- Breathlessness during activity
- Pale skin appearance
- Reduced stamina and energy
Feeling constantly drained? Get checked by the specialists at Lux Hospitals.
6. Feeling of Incomplete Emptying
A sense that the bowel never fully empties can be an early clue. This happens when a growth blocks part of the colon.
The urge may persist even right after a bowel movement.
You may experience:
- Constant urge to pass stool
- Feeling of leftover stool
- Straining without relief
- Frequent trips to the toilet
7. Iron-Deficiency Anaemia
Colon cancer can cause anaemia through slow, unnoticed blood loss. It is sometimes found on a routine blood test before other symptoms.
In men and postmenopausal women, unexplained anaemia always warrants investigation.
Signs of anaemia include:
- Low haemoglobin on blood tests
- Dizziness or light-headedness
- Cold hands and feet
- Rapid or irregular heartbeat
Other Conditions That Mimic Symptoms
Many colon cancer symptoms overlap with less serious conditions. Only proper testing can tell them apart.
Do not self-diagnose based on symptoms alone.

Colon Cancer Risk Factors
Certain factors raise your chance of developing colon cancer. Knowing them helps you decide when to start screening.
Some risks you can change, others you cannot.
Major risk factors include:
- Age over 50
- Family history of colorectal cancer
- History of colon polyps
- Inflammatory bowel disease
- Diet high in red or processed meat
- Smoking and heavy alcohol use
How Colon Cancer Is Diagnosed
Doctors use several tests to confirm colon cancer and stage it. Colonoscopy remains the gold standard.
Early screening can catch cancer before symptoms appear.
Common diagnostic tools include:
- Colonoscopy with biopsy
- Stool tests for hidden blood
- CT scan or CT colonography
- Blood tests including tumour markers
- Imaging to check for spread
