Dr. Pavan Kumar C. G. is a Consultant Surgical Oncologist and Robotic & Advanced Laparoscopic Cancer Surgeon practising in Hubli-Dharwad. He specialises in gastrointestinal cancers, breast cancer, oral cancer, gynecological cancers and soft-tissue tumours.
Here are seven symptoms that deserve medical attention when persistent or unexplained.
1. Blood in the Stool
Blood may appear bright red or make stools unusually dark.
Although piles and other non-cancerous conditions can also cause rectal bleeding, persistent or unexplained blood in the stool should be evaluated rather than self-treated repeatedly.
The National Cancer Institute lists blood in the stool among important signs of colon cancer.
2. Persistent Change in Bowel Habits
Watch for a persistent change such as:
- New constipation
- Repeated diarrhoea
- Feeling that the bowel has not emptied completely
- Unusual change in stool shape
These symptoms have many possible causes, but persistent changes deserve proper medical evaluation.
3. Repeated Abdominal Pain
Frequent or unexplained abdominal pain, cramps or discomfort should not always be dismissed as gas or acidity.
Research highlighted by the NCI identified abdominal pain among four warning signs associated with colorectal cancer in younger adults.
4. Unexplained Weight Loss
Losing weight without intentionally changing your diet or exercise routine deserves attention—especially when it occurs together with altered bowel habits, bleeding or persistent abdominal symptoms.
Do not simply assume unexplained weight loss is caused by stress or reduced appetite.
5. Unexplained Anaemia or Extreme Tiredness
Slow bleeding from the digestive tract can sometimes contribute to iron-deficiency anaemia.
Symptoms can include weakness, tiredness, dizziness or breathlessness.
Iron-deficiency anaemia was also identified as an important potential warning sign for early-onset colorectal cancer.
6. Do Not Assume You Are “Too Young” for Colon Cancer
Colorectal cancer is often associated with older adults, but symptoms should not automatically be ignored simply because someone is young.
NCI research has highlighted rectal bleeding, abdominal pain, diarrhoea and iron-deficiency anaemia as potential warning signs that deserve attention in younger adults.
7. Know When Screening May Be Needed
Screening aims to identify abnormal tissue or cancer before symptoms develop. Colon and rectal cancers can begin as polyps, and finding and removing some polyps can prevent colorectal cancer from developing.
Screening recommendations depend on age, family history, inherited conditions and individual risk. People with symptoms should seek medical evaluation rather than waiting until a routine screening age.

When Should You See a Cancer Surgeon?
Consider specialist evaluation if you have persistent blood in stool, unexplained bowel changes, recurring abdominal pain, unexplained anaemia or weight loss, particularly when symptoms continue or worsen.
Having these symptoms does not automatically mean cancer. Proper examination and appropriate investigations are needed to identify the cause.

Persistent bowel changes, rectal bleeding or unexplained abdominal symptoms should not be ignored. Timely evaluation can help identify the cause and, when cancer is present, support earlier treatment planning.
