Colorectal cancer — cancer of the colon and rectum — is among the most preventable and most treatable of all cancers when detected early. At Stage 1, the five-year survival rate exceeds 90 percent. Surgery alone, without chemotherapy or radiotherapy, is curative in the majority of Stage 1 cases. And yet in India, the overwhelming majority of colorectal cancer patients present at Stage 3 or Stage 4, when the disease has spread to lymph nodes or distant organs, treatment is substantially more complex, and outcomes are considerably less certain. As a rectum cancer surgeon in Aurangabad, Dr. Akash Mor at drakashmor.com has operated on patients across this entire spectrum and understands precisely why this gap between the treatable and the treated exists.
The answer is not a mystery. It is a combination of symptom misattribution, social taboo around bowel health, lack of awareness about screening, and a healthcare culture that treats digestive symptoms as benign until proven otherwise. Changing this pattern requires public awareness, and this blog is a contribution to that effort. Find Dr. Akash Mor on Google to speak to our surgical team.

Why Colorectal Cancer Is So Consistently Missed in Its Early Stages
The Symptoms Are Easy to Dismiss
Early colorectal cancer produces symptoms that are individually explainable by far more common benign conditions. A change in bowel habits is attributed to dietary change or stress. Blood in the stool is attributed to haemorrhoids — which affects a large proportion of the adult population and does genuinely cause rectal bleeding. Mild abdominal discomfort is attributed to gas or indigestion. Fatigue is attributed to overwork. Each of these attributions is individually plausible, which is exactly why they succeed in delaying diagnosis.
Bowel Symptoms Carry Social Stigma
Symptoms related to bowel function are among the least discussed in social and family settings. Patients are often reluctant to describe their bowel habits even to their doctor, let alone to family members who might encourage them to seek care. This social taboo around gastrointestinal symptoms creates a systematic delay between symptom onset and medical consultation that is unique to this organ system. Patients who would promptly seek care for a lump in the breast or blood in the urine will wait months or years before discussing rectal bleeding with their doctor.
Haemorrhoids as the Default Explanation
Haemorrhoids are genuinely common — they affect an estimated 75 percent of adults at some point in their lives. This prevalence makes them the default explanation for rectal bleeding, and the explanation is accepted by patients and sometimes by doctors without adequate investigation. The critical clinical principle is this: haemorrhoids do not cause a change in bowel habits, they do not cause iron deficiency anaemia, and they do not cause weight loss. When rectal bleeding is accompanied by any of these additional features, haemorrhoids are not a sufficient explanation and investigation is mandatory.
Rectal bleeding should never be attributed to haemorrhoids without a proper examination. A colonoscopy is the only investigation that can definitively exclude colorectal cancer as a cause of rectal bleeding in at-risk patients.

The Warning Signs That Must Not Be Ignored
The following symptoms, particularly when they persist for more than four weeks or occur in patients over 40, require formal medical evaluation and should not be attributed to benign causes without investigation:
• Blood in or on the stool — whether bright red (typically from the lower colon or rectum) or dark and mixed with stool (typically from higher in the colon)
• A persistent change in bowel habits lasting more than four weeks — new constipation, looser stools, narrower stools, or increased frequency
• A feeling of incomplete evacuation after a bowel movement — the sensation that the bowel has not emptied fully
• Unexplained iron deficiency anaemia — fatigue, pallor, and breathlessness due to chronic blood loss from a colonic tumour, often without visible blood in the stool
• Abdominal pain or cramping that is new, persistent, or progressive
• Unexplained weight loss alongside any digestive symptom
• A palpable abdominal mass — a lump felt in the abdomen
The Role of Colonoscopy in Early Detection
A colonoscopy is the definitive investigation for the colon and rectum. It allows direct visualisation of the entire large bowel lining, identification of polyps (precancerous growths) and tumours, and biopsy of suspicious lesions. Crucially, colonoscopy is not just diagnostic — it is also preventive. Colorectal polyps, if identified and removed during colonoscopy before they become malignant, prevent cancer from developing at all. This makes colonoscopy the only cancer screening test that is simultaneously diagnostic and preventive.
In Western countries, colonoscopy screening for average-risk individuals begins at age 45 to 50. In India, formal population-level screening programmes do not yet exist, but individual screening colonoscopy is available and is recommended for patients with a family history of colorectal cancer, inflammatory bowel disease, or a personal history of colonic polyps.
What Happens When Colorectal Cancer Is Diagnosed at Each Stage
Stage 1 — Surgery Alone, Highly Curative
The cancer is confined to the inner layers of the colon or rectal wall. Surgical resection with adequate margins and removal of regional lymph nodes is the primary treatment and is curative in the vast majority of cases. No chemotherapy or radiotherapy is required in most Stage 1 cases. Five-year survival exceeds 90 percent.
Stage 2 — Surgery, Sometimes With Adjuvant Treatment
The cancer has grown through the bowel wall but has not spread to lymph nodes. Surgery remains the primary treatment. Adjuvant chemotherapy may be recommended in high-risk Stage 2 cases. Five-year survival is 75 to 85 percent.
Stage 3 — Surgery Plus Chemotherapy
The cancer has spread to regional lymph nodes. Treatment involves surgery combined with adjuvant chemotherapy. For rectal cancer at Stage 3, neoadjuvant chemoradiotherapy — given before surgery to shrink the tumour — is often recommended to improve the chance of complete surgical clearance and reduce the risk of local recurrence. Five-year survival is 40 to 65 percent depending on the number of lymph nodes involved.
Stage 4 — Metastatic Disease, Complex Multidisciplinary Management
The cancer has spread to distant organs, most commonly the liver and lungs. Treatment involves chemotherapy, targeted therapy, and surgery where possible. Liver metastases from colorectal cancer are potentially resectable in selected patients, and surgical removal of liver metastases offers the possibility of long-term survival in approximately 25 to 40 percent of cases. Five-year survival for Stage 4 disease is approximately 10 to 15 percent overall, with better outcomes in the subset of patients whose metastases are surgically resectable.
The Surgical Approach to Colorectal Cancer at Dr. Akash Mor’s Practice
At Dr. Akash Mor’s colorectal cancer surgical practice, every patient undergoes a comprehensive preoperative assessment including CT staging, MRI for rectal cancers to assess the relationship between the tumour and the mesorectal fascia, colonoscopy, and multidisciplinary team review. The surgical approach — open, laparoscopic, or robotic — is selected based on the tumour location, stage, and the patient’s anatomy.
The oncological principle guiding every colorectal cancer operation is total mesorectal excision (TME) for rectal cancer and adequate colonic resection with complete mesocolic excision (CME) for colon cancer — techniques that maximise lymph node yield and reduce local recurrence rates. These are the internationally recognised gold standards for colorectal cancer surgery and are consistently applied at every operation.
Frequently Asked Questions
Q: Will I need a colostomy bag after colorectal cancer surgery?
Not necessarily. The need for a permanent colostomy depends on the location of the tumour — very low rectal cancers close to the sphincter muscle may require a permanent stoma. The majority of colon cancers and most rectal cancers at or above a certain level from the anal margin can be treated without a permanent stoma. A temporary loop ileostomy is sometimes created to protect a low rectal anastomosis and is reversed after six to twelve weeks.
Q: How is colorectal cancer different from haemorrhoids in terms of symptoms?
Haemorrhoids cause bright red bleeding that is typically separate from the stool, associated with straining, and not accompanied by changes in bowel habits, weight loss, or fatigue. Colorectal cancer may cause blood mixed with the stool, a persistent change in bowel habits, a feeling of incomplete evacuation, and systemic symptoms. When in doubt, a colonoscopy provides a definitive answer that a clinical examination alone cannot.
At what age should I have my first colonoscopy if I have no symptoms?
For average-risk individuals with no family history or personal history of polyps or colorectal cancer, a first screening colonoscopy is generally recommended at age 45 to 50. For individuals with a first-degree relative who had colorectal cancer, screening should begin at age 40 or ten years before the relative’s age at diagnosis, whichever is earlier.
