Colorectal Cancer Can Develop Without Symptoms

The importance of screening and understanding risk factors.

Why it matters even without symptoms

Colorectal cancer can develop without obvious symptoms. That is why screening exists: it looks for the disease in people who feel well.

Who should discuss screening?

Screening should be discussed according to age and risk, particularly for people with a family history or other relevant risk factors.

Is all blood in the stool caused by cancer?
No. There are many possible causes, but recurrent bleeding should be assessed.

If your symptoms persist or you are unsure of the cause, arrange an assessment.

Colorectal cancer affects the colon or rectum. Earlier detection may provide more treatment options. Blood colour alone cannot tell you the cause of bleeding. Do not assume that blood in the stool is caused by haemorrhoids.

When should you be assessed?

  • Blood in the stool
  • A change in bowel habits
  • Persistent constipation or diarrhoea
  • Unexplained weight loss
  • Anaemia or unusual tiredness
  • Persistent abdominal pain or bloating

Treatment Options

Treatment depends on the site and stage of the cancer. Surgery may be performed laparoscopically or through an open approach. Depending on the location and stage of the cancer, treatment may also include chemotherapy and, particularly for rectal cancer, radiotherapy. Your care is planned with a multidisciplinary team of specialists.
