Colon & Rectal Cancer in Bangladesh:
Dr. Muhammad Nazrul Islam — Dhaka’s specialist colorectal surgeon — sees this pattern repeatedly in his clinic. The purpose of this page is to change it: by putting the correct information about কোলন ক্যান্সারের লক্ষণ (colon cancer symptoms in Bengali) clearly before every Bangladeshi patient who needs it.
⚠️ Critical Summary — কোলন ক্যান্সার সম্পর্কে যা জানা জরুরি
- কোলন ক্যান্সার / Colorectal cancer = the 3rd most common cancer globally — and rising in Bangladesh, now affecting people under 40
- Most common early symptom: rectal bleeding — yet 80% of Bangladeshi patients initially assume it is পাইলস
- Stage 1 survival rate: 90%+ | Stage 4 survival rate: less than 15% — early detection is everything
- Colonoscopy is the only test that both detects AND prevents colorectal cancer — available in Dhaka
- Key Bangladesh risk factors: low-fibre diet, red meat, পান-সুপারি (betel nut), physical inactivity, family history
- Do NOT dismiss rectal bleeding as পাইলস without examination — both can coexist
- Colon cancer IS curable when caught early — surgery alone cures the majority of Stage 1 and 2 cases
কোলন ক্যান্সার মানে কী? / What is Colorectal Cancer? (কোলন ক্যান্সারের বাংলা অর্থ)
কোলন ক্যান্সার (colon cancer) বাংলায় — মলান্ত্রের ক্যান্সার বা মলাশয়ের ক্যান্সার নামেও পরিচিত। চিকিৎসা বিজ্ঞানে একে Colorectal Cancer বলা হয় — যার অর্থ হলো বৃহদন্ত্র (colon) বা মলদ্বারের কাছের অংশ (rectum)-এ কোষের অস্বাভাবিক বৃদ্ধি যা ক্যান্সারে পরিণত হয়।
Colorectal cancer is one disease that begins in the lining of the large intestine. When it starts in the colon it is called colon cancer. When it starts in the last 15cm of the intestine just before the anus, it is called rectal cancer. Together they are called colorectal cancer — they share the same risk factors, warning signs and treatment approach.
According to the WHO Colorectal Cancer Fact Sheet ↗, colorectal cancer is the third most common cancer worldwide and the second leading cause of cancer death. In Bangladesh, the incidence is rising — and alarmingly, cases in patients under 40 are increasing. Unlike many cancers, colorectal cancer is almost entirely preventable and curable when detected early.
কোলন ক্যান্সারের লক্ষণ কী কী? / Colon Cancer Symptoms in Bengali — 8 Warning Signs
কোলন ক্যান্সারের লক্ষণ (colon cancer symptoms in Bengali) জানা এই রোগ থেকে বাঁচার প্রথম পদক্ষেপ। বেশিরভাগ রোগী এই লক্ষণগুলো বছরের পর বছর উপেক্ষা করেন — কারণ সেগুলো পাইলস বা সাধারণ হজমের সমস্যা মনে হয়। নিচের ৮টি সতর্কতামূলক লক্ষণ মনোযোগ দিয়ে পড়ুন:
Warning Sign 1: পায়খানায় রক্ত / Rectal Bleeding — The Most Important Sign
Blood in the stool (পায়খানায় রক্ত) is the most important warning sign of colorectal cancer — and the most commonly dismissed. In Bangladesh, 80% of patients with rectal bleeding assume it is পাইলস and self-treat for months. While পাইলস is far more common than cancer, it is never safe to assume rectal bleeding is পাইলস without an examination. Both can coexist — and a colorectal cancer can bleed alongside existing piles.
Warning Sign 2: পায়খানার অভ্যাসে পরিবর্তন / Change in Bowel Habit
A persistent change in bowel habit lasting more than 3 weeks is a major red flag for colorectal cancer. This includes: new constipation (কোষ্ঠকাঠিন্য) that was not present before, new diarrhoea or loose stools, alternating constipation and diarrhoea, a feeling of incomplete evacuation (মনে হয় পায়খানা পুরোপুরি হচ্ছে না), or stools that are narrower than usual (pencil-thin stools). Any of these changes — especially in a person over 40 — must be investigated.
Warning Sign 3: পেটে ব্যথা ও অস্বস্তি / Persistent Abdominal Pain or Discomfort
Persistent cramps, gas or pain in the abdomen — especially in the lower left side — that does not resolve with dietary changes is a warning sign. The pain from colon cancer is often described as a dull aching or cramping discomfort rather than severe acute pain. Many patients dismiss this as ‘গ্যাসের সমস্যা’ (gas pain) for months.
Warning Sign 4: অকারণে ওজন কমে যাওয়া / Unexplained Weight Loss
Losing more than 5% of body weight over 6 months without trying — with no change in diet or exercise — is one of the most important cancer warning signs. In colorectal cancer, weight loss occurs because the tumour consumes calories and causes systemic inflammation. This sign is often present in more advanced disease.
Warning Sign 5: দুর্বলতা ও ক্লান্তি / Unexplained Fatigue and Weakness
Persistent unexplained tiredness and weakness is often caused by chronic blood loss from a colorectal tumour — even when the blood loss is not visible in the stool (occult bleeding). The resulting iron-deficiency anaemia causes fatigue, pallor and breathlessness. In Bangladesh, many patients with colorectal cancer present with anaemia and are treated for ‘anaemia’ for months without the underlying cancer being found.
Warning Sign 6: মলের মধ্যে শ্লেষ্মা / Mucus in the Stool
Passing mucus (শ্লেষ্মা / আঠালো পদার্থ) with or without blood in the stool is a warning sign of colorectal disease. While mucus can occur with inflammatory bowel disease or infection, it can also indicate rectal cancer. Mucus mixed with blood is a particularly important warning sign.
Warning Sign 7: পেট ফাঁপা ও গ্যাস / Persistent Bloating and Gas
Persistent bloating, excessive gas and a feeling of abdominal fullness that does not respond to dietary changes can indicate a partial bowel obstruction from a growing tumour. This is more common with left-sided colon cancers.
Warning Sign 8: মলদ্বারে চাপ অনুভব / Rectal Pressure or Incomplete Emptying
A persistent feeling of needing to open the bowels even after doing so — called tenesmus — is a key symptom of rectal cancer. The sensation of a lump or pressure in the rectum, or feeling that the bowel has not fully emptied after a bowel movement, is a direct symptom of a rectal tumour. See also our guide on perianal symptoms which may accompany these signs.
কোলন ক্যান্সারের ৮টি সতর্কতামূলক লক্ষণ / 8 Warning Signs in Bengali:
- পায়খানায় রক্ত (rectal bleeding) — সবচেয়ে গুরুত্বপূর্ণ লক্ষণ
- পায়খানার অভ্যাসে পরিবর্তন — নতুন কোষ্ঠকাঠিন্য বা ডায়রিয়া, ৩ সপ্তাহের বেশি স্থায়ী
- পেটে ব্যথা বা ক্রমাগত অস্বস্তি — বিশেষত বাম দিকে
- অকারণে ওজন কমে যাওয়া — ৬ মাসে ৫% বা বেশি
- দুর্বলতা ও ক্লান্তি — অ্যানিমিয়া থেকে
- মলের মধ্যে শ্লেষ্মা বা আঠালো পদার্থ
- পেট ফাঁপা ও গ্যাস — খাদ্য পরিবর্তনেও ভালো হচ্ছে না
- মলদ্বারে চাপ অনুভব বা মলত্যাগের পরও অসম্পূর্ণ মনে হওয়া
পাইলস না কোলন ক্যান্সার? / Piles vs Colorectal Cancer — A Critical Bangladesh-Specific Issue
The single most dangerous misconception in Bangladesh’s colorectal health landscape is this: ‘পায়খানায় রক্ত মানেই পাইলস’ — ‘blood in stool means piles’. This belief is widespread, culturally reinforced, and directly responsible for late-stage colorectal cancer diagnoses across Bangladesh. Here is the factual picture:
| Feature | পাইলস / Piles | কোলন ক্যান্সার / Colorectal Cancer |
|---|---|---|
| Blood colour | Bright red — on paper, dripping after stool | Dark red or maroon — mixed IN the stool |
| Pain with bleeding | Often painless or burning around anus | Rarely associated with bleeding in early stages |
| Weight loss | No | Yes — unexplained weight loss is a red flag |
| Fatigue / anaemia | No (except very heavy bleeding) | Yes — chronic occult blood loss |
| Bowel habit change | No | Yes — key distinguishing feature |
| Age risk | Any age | Risk rises sharply after 40 |
| Can they coexist? | YES — this is the danger. Piles can mask cancer bleeding at the same time. | |
| What to do | See Dr. Nazrul for examination | See Dr. Nazrul urgently — same visit |
কোলন ক্যান্সারের কারণ কী? / Causes and Risk Factors of Colorectal Cancer in Bangladesh
Colorectal cancer arises from the abnormal growth of cells in the colon or rectum lining — usually beginning as non-cancerous polyps that gradually become malignant over 10–15 years. Understanding the risk factors helps identify who needs earlier screening:
Bangladesh-Specific Risk Factors / বাংলাদেশে বিশেষ ঝুঁকি
- কম আঁশযুক্ত খাবার (Low-fibre diet) — the typical Bangladeshi urban diet is high in refined rice and processed foods and very low in vegetables, whole grains and legumes. Dietary fibre is the single most protective dietary factor against colorectal cancer.
- লাল মাংস ও প্রক্রিয়াজাত মাংস (Red and processed meat) — high consumption of beef, mutton and processed meats is well-established as a colorectal cancer risk factor (WHO IARC Group 1 carcinogen for processed meat).
- পান-সুপারি (Betel nut / Areca nut) — one of the most important and under-recognised risk factors in Bangladesh. Betel nut chewing is extremely common in Bangladesh and is classified as a Group 1 carcinogen by the WHO IARC. It significantly increases risk of colorectal and other gastrointestinal cancers.
- শারীরিক নিষ্ক্রিয়তা (Physical inactivity) — sedentary urban lifestyle increases colorectal cancer risk by 20–30%.
- স্থূলতা (Obesity) — rising rapidly in urban Bangladesh; increases colorectal cancer risk, particularly in men.
- ধূমপান (Smoking) — smokers have a 20% higher risk of developing colorectal cancer.
General Risk Factors / সাধারণ ঝুঁকি
- বয়স (Age) — risk rises sharply after 40, and particularly after 50. However, cases under 40 are increasing in Bangladesh — do not assume young age provides protection.
- পারিবারিক ইতিহাস (Family history) — a first-degree relative (parent, sibling, child) with colorectal cancer doubles your risk. Lynch syndrome and familial adenomatous polyposis (FAP) carry very high lifetime risk and require surveillance from an early age.
- পূর্ববর্তী পলিপ (Previous polyps) — adenomatous polyps removed from the colon have a risk of recurring and eventually becoming malignant; regular colonoscopy surveillance is essential.
- Inflammatory bowel disease — Crohn’s disease and ulcerative colitis significantly increase long-term colorectal cancer risk, particularly with disease lasting more than 8–10 years.
- Diabetes — Type 2 diabetes is associated with a 30% increased risk of colorectal cancer, partly through insulin resistance.
কোলন ক্যান্সারের স্তর / Colorectal Cancer Stages — Why Early Detection Saves Lives
Colorectal cancer is staged from Stage 1 to Stage 4 based on how far it has spread. The stage at diagnosis is the single most important factor determining treatment and survival. This is why early detection is so critical:
| Stage / স্তর | Description / বিবরণ | 5-Year Survival / বেঁচে থাকার হার |
|---|---|---|
| Stage 1 | Cancer confined to inner layers of colon wall. No spread to lymph nodes or other organs. মলান্ত্রের ভেতরের স্তরেই সীমাবদ্ধ। | 90%+ — surgery alone cures most cases |
| Stage 2 | Cancer has grown through colon wall into surrounding tissue but NOT spread to lymph nodes. মলান্ত্রের দেয়াল পেরিয়েছে। | 75–85% — surgery usually curative |
| Stage 3 | Cancer has spread to nearby lymph nodes. লিম্ফ নোডে ছড়িয়েছে। Surgery + chemotherapy required. | 40–65% — treatment required, curable in many cases |
| Stage 4 | Cancer has spread to distant organs — liver, lungs, peritoneum. দূরের অঙ্গে ছড়িয়েছে। | Less than 15% — palliative and targeted treatment |
কোলন ক্যান্সার কীভাবে নির্ণয় করা হয়? / How is Colorectal Cancer Diagnosed?
If you have symptoms that concern you or your doctor, the following tests are used to investigate:
| Test / পরীক্ষা | What It Does / কী করে |
|---|---|
| Colonoscopy (কোলোনোস্কোপি) | Gold standard — a flexible camera examines the entire large intestine. Can both diagnose AND remove polyps in the same procedure. Available in Dhaka. |
| Flexible sigmoidoscopy | Camera examination of the lower colon and rectum only — quicker, no full bowel prep, but misses right-sided cancers. |
| CT colonography (virtual colonoscopy) | CT scan reconstructing the inside of the colon. Less invasive but cannot remove polyps; requires follow-up colonoscopy if abnormality found. |
| CT scan (CT স্ক্যান) | Can detect large tumours and assess spread — but CANNOT detect early cancer or polyps. NOT a substitute for colonoscopy for diagnosis. |
| MRI pelvis | Essential for staging rectal cancer before surgery — maps the tumour’s relation to the sphincters and surrounding structures. |
| FIT test (Faecal Immunochemical Test) | Stool test detecting hidden blood. Cheap, non-invasive, used for population screening. A positive result requires follow-up colonoscopy. |
| Blood tests: CEA, CBC, LFTs | CEA (carcinoembryonic antigen) is a tumour marker — elevated in some colorectal cancers. CBC detects anaemia from blood loss. LFTs assess liver involvement. |
| Biopsy | Tissue sample taken during colonoscopy — definitive diagnosis of cancer vs benign polyp. |
কোলন ক্যান্সারের চিকিৎসা / Colorectal Cancer Treatment in Bangladesh — What Are the Options?
Treatment depends on stage, location (colon vs rectum), the patient’s general health and whether surgery is feasible. Dr. Nazrul Islam provides surgical treatment for colorectal cancer in Dhaka. Survival rates for each stage are published by the American Cancer Society ↗.
Surgery / অস্ত্রোপচার — The Primary Treatment
Surgery is the mainstay of curative treatment for Stage 1–3 colorectal cancer and selected Stage 4 cases. The type of operation depends on the location of the cancer:
- Right hemicolectomy — removal of the right side of the colon for cancers of the caecum, ascending colon and hepatic flexure
- Left hemicolectomy / sigmoid colectomy — removal of the left side of the colon and sigmoid for left-sided cancers
- Anterior resection — for rectal cancer in the upper and middle rectum; the rectum is removed and the colon joined to the remaining rectum (anastomosis). Most patients retain normal bowel function.
- Abdominoperineal resection (APR) — for cancers of the very low rectum close to the anal sphincter; requires a permanent colostomy (stoma bag)
- Laparoscopic (keyhole) surgery — minimally invasive approach with smaller incisions, faster recovery and equivalent cancer outcomes to open surgery
- Endoscopic polypectomy — removal of pre-cancerous polyps during colonoscopy before they become cancer — the most effective prevention
Chemotherapy / কেমোথেরাপি
Used after surgery (adjuvant chemotherapy) for Stage 3 colon cancer to kill remaining cancer cells and reduce recurrence risk. Standard regimens include FOLFOX or CAPOX. Also used as palliative treatment for Stage 4 disease.
Radiotherapy / রেডিওথেরাপি
Used primarily for rectal cancer — usually given BEFORE surgery (neoadjuvant) to shrink the tumour and reduce the chance of local recurrence. The combination of radiotherapy + chemotherapy followed by surgery (chemoradiotherapy) is the international standard for locally advanced rectal cancer. Not routinely used for colon cancer.
Targeted Therapy and Immunotherapy
For Stage 4 colorectal cancer, targeted biological agents (bevacizumab, cetuximab) and immunotherapy (pembrolizumab for MSI-H/dMMR tumours) are increasingly used in Bangladesh’s major oncology centres alongside chemotherapy.
কোলন ক্যান্সার স্ক্রিনিং / Colorectal Cancer Screening in Dhaka — Who Should Get Tested and When?
Colorectal cancer screening finds cancer or pre-cancerous polyps BEFORE symptoms develop — when it is most curable. This is the most important section for patients without symptoms who have risk factors:
| Who Should Be Screened / কার স্ক্রিনিং করা উচিত | When to Start / কখন শুরু করবেন |
|---|---|
| Average risk — no family history, no symptoms | Start at age 40–45. Colonoscopy every 10 years if normal. |
| Family history of colorectal cancer (1st-degree relative) | Start 10 years before the age at which the relative was diagnosed, or at age 40 — whichever is earlier. Colonoscopy every 5 years. |
| Lynch syndrome or FAP (hereditary syndromes) | Start at age 20–25. Annual or biennial colonoscopy for life. |
| Previous adenomatous polyps removed | Colonoscopy every 3–5 years depending on polyp type and number. |
| Inflammatory bowel disease (IBD — Crohn’s, UC) | Annual colonoscopy after 8–10 years of disease. |
| Unexplained rectal bleeding at ANY age | Immediate colonoscopy — do not wait for screening age. |
| Symptoms suggesting cancer at ANY age | Urgent colonoscopy — investigation and, if polyp found, treatment in one procedure. |
কোলন ক্যান্সার প্রতিরোধ / How to Prevent Colorectal Cancer — Evidence-Based Steps
Up to 50% of colorectal cancers could be prevented with lifestyle changes. These measures are supported by strong evidence:
- আঁশযুক্ত খাবার বাড়ান (Increase dietary fibre) — vegetables, fruits, legumes (ডাল), whole grains. Every 10g/day increase in fibre reduces colorectal cancer risk by ~10%.
- লাল মাংস কমান (Reduce red and processed meat) — limit beef and mutton to maximum 2 servings/week. Avoid processed meats (sausage, কিমা, smoked meats) as much as possible.
- পান-সুপারি এড়িয়ে চলুন (Avoid betel nut) — a proven Group 1 carcinogen. Stopping this one habit reduces risk of multiple gastrointestinal cancers.
- নিয়মিত শারীরিক ব্যায়াম (Regular physical activity) — 30 minutes of moderate exercise 5 days/week reduces colorectal cancer risk by 24%.
- ওজন নিয়ন্ত্রণ (Maintain healthy weight) — obesity increases risk; losing excess weight reduces it.
- ধূমপান ও মদ্যপান পরিহার (Avoid smoking and alcohol).
- নিয়মিত স্ক্রিনিং (Regular screening) — colonoscopy every 10 years from age 40–45 for average-risk individuals. Polyps removed at colonoscopy prevent cancer from developing.
- পারিবারিক ইতিহাস জানুন (Know your family history) — inform Dr. Nazrul of any first-degree relative with colorectal cancer. Earlier and more frequent screening may be advised.
Frequently Asked Questions / সচরাচর জিজ্ঞাসা —
These questions are written exactly as people speak them to Google Assistant, Siri and Alexa — and to their doctors. Each answer begins with a short direct response that voice assistants can read aloud.
What are the early symptoms of colon cancer? / কোলন ক্যান্সারের প্রাথমিক লক্ষণ কী?
Quick answer: The most important early symptoms are blood in the stool, a change in bowel habit lasting more than 3 weeks, and unexplained fatigue from anaemia — all of which are frequently dismissed as পাইলস or digestive problems.
Early-stage colon cancer often causes very subtle symptoms. The 8 warning signs are: (1) rectal bleeding, (2) persistent change in bowel habit, (3) abdominal pain or discomfort, (4) unexplained weight loss, (5) fatigue and anaemia, (6) mucus in the stool, (7) persistent bloating, and (8) feeling of incomplete bowel emptying. Crucially, Stage 1 colon cancer sometimes has NO symptoms at all — which is why screening is so important for people over 40.
Is colon cancer curable? / কোলন ক্যান্সার কি ভালো হয়?
Quick answer: Yes — colon cancer is highly curable when caught early. Stage 1 has a 90%+ cure rate with surgery alone. Even Stage 3 is curable in 40–65% of cases with surgery and chemotherapy.
The curability of colon cancer depends entirely on the stage at diagnosis. Stage 1: 90%+ 5-year survival. Stage 2: 75–85%. Stage 3: 40–65%. Stage 4: less than 15%. The same cancer that is 90% curable at Stage 1 becomes 85% fatal by Stage 4. This is why early detection through awareness of symptoms and regular screening is so critical.
Is rectal cancer painful? / রেকটাল ক্যান্সার কি ব্যথাদায়ক?
Quick answer: Early rectal cancer is often painless — this is one reason it is diagnosed late. Pain typically indicates more advanced disease with the tumour pressing on surrounding structures.
Rectal cancer in its early stages is frequently painless. The most common symptom is rectal bleeding — which is also often painless. As the cancer grows, patients may experience a feeling of rectal pressure or incomplete emptying (tenesmus), dull aching pain in the lower pelvis, and pain during bowel movements. The absence of pain does NOT mean the cancer is not serious.
Does colon cancer cause constipation? / কোলন ক্যান্সার কি কোষ্ঠকাঠিন্য করে?
Quick answer: Yes — a growing colon tumour can partially block the bowel, causing new constipation or alternating constipation and diarrhoea. New constipation in a person over 40 that was not previously present is always a red flag.
Left-sided colon cancers and rectal cancers are more likely to cause constipation because the left side of the colon has a narrower diameter. A tumour growing here can cause pencil-thin stools, a feeling of incomplete emptying, or complete bowel obstruction in advanced cases. New persistent constipation (কোষ্ঠকাঠিন্য) in a person over 40, especially if associated with any bleeding or weight loss, requires investigation.
Can a CT scan detect colon cancer? / CT স্ক্যান দিয়ে কি কোলন ক্যান্সার ধরা পড়ে?
Quick answer: A CT scan can detect large or advanced colon cancer and assess spread to other organs — but it CANNOT detect early-stage cancer or pre-cancerous polyps. Colonoscopy is the required test for early detection.
CT scans are useful for staging (finding out if cancer has spread to the liver or lungs), planning surgery, and monitoring treatment response. For early detection and screening, colonoscopy is the gold standard — it can find polyps smaller than 5mm and remove them in the same procedure. If you have symptoms of colon cancer and your doctor has only ordered a CT scan without colonoscopy, ask specifically about colonoscopy.
Do women get colon cancer? / মহিলারা কি কোলন ক্যান্সারে আক্রান্ত হন?
Quick answer: Yes — colorectal cancer affects both men and women. While it is slightly more common in men overall, women are at equal risk after age 50, and the warning signs are identical.
In Bangladesh, both men and women develop colorectal cancer, and the symptoms are the same: rectal bleeding, change in bowel habit, abdominal pain, weight loss and fatigue. Women sometimes delay seeking help because they attribute symptoms to gynaecological causes. Any woman with persistent rectal bleeding, especially over age 40, should have a proper colorectal examination.
How do I know if I have colon cancer or piles? / পাইলস না কোলন ক্যান্সার — কীভাবে বুঝব?
Quick answer: You cannot tell the difference without an examination. Both cause rectal bleeding. The only way to know for certain is a proper examination by a colorectal surgeon — this takes 5 minutes and could save your life.
Bright red blood on toilet paper or dripping into the bowl after a soft stool is more typical of পাইলস. Dark red blood mixed within the stool, bleeding with weight loss or fatigue, or any new bowel habit change alongside bleeding is more concerning for cancer. However — both conditions can coexist, and NO amount of online research substitutes for a 5-minute examination. See Dr. Nazrul Islam in Dhaka for a definitive answer.
How to prevent colon cancer? / কোলন ক্যান্সার কীভাবে প্রতিরোধ করা যায়?
Quick answer: The most important preventive steps are: eat more vegetables and fibre, reduce red and processed meat, avoid betel nut (পান-সুপারি), exercise regularly, maintain a healthy weight, and get a colonoscopy from age 40 onwards.
Up to 50% of colorectal cancers are preventable. In Bangladesh, the most impactful changes are: stopping পান-সুপারি, reducing red meat intake, increasing vegetables and legumes in the daily diet, and getting a colonoscopy from age 40. Colonoscopy is uniquely preventive — polyps found during the procedure are removed before they can become cancer. A single colonoscopy every 10 years from age 40 dramatically reduces lifetime colorectal cancer risk.
কোলন ক্যান্সারের চিকিৎসা বাংলাদেশে কোথায় পাওয়া যায়?
Quick answer: ঢাকায় ডা. মুহাম্মদ নজরুল ইসলাম-এর ক্লিনিকে কোলন ও রেকটাল ক্যান্সারের অস্ত্রোপচার ও চিকিৎসা পাওয়া যায়। সিরিয়ালের জন্য কল করুন: +88019 7684 2234
Bangladesh has several centres providing colorectal cancer treatment in Dhaka. Dr. Muhammad Nazrul Islam — FCPS (Surgery), MS (Colorectal Surgery), FACS — provides colorectal cancer surgery and assessment at his Dhaka clinic. Chemotherapy and radiotherapy are available at oncology departments of major hospitals including DMCH, BSMMU and private cancer centres. For surgical assessment and colonoscopy, book an appointment online or call +88019 7684 2234.
What is the survival rate for colorectal cancer in Bangladesh?
Quick answer: Overall colorectal cancer survival in Bangladesh is lower than in Western countries — primarily because most patients are diagnosed at Stage 3 or Stage 4. When caught at Stage 1, survival is 90%+. When caught at Stage 4, it is less than 15%.
Based on available data and the pattern seen at Dr. Nazrul’s clinic, the majority of patients present late — at Stage 3 or 4 — because of delayed diagnosis. Global data shows that when detected early (Stage 1), 90% of patients are alive 5 years later. The key to improving Bangladesh’s colorectal cancer outcomes is earlier diagnosis through awareness and screening.
কোলন ক্যান্সারের কোনো লক্ষণ আছে? / Any Warning Signs of Colon Cancer?
Colorectal cancer is highly curable when caught early — Stage 1 has a 90%+ survival rate; Stage 4 has less than 15%. The difference is time. If you have rectal bleeding, unexplained weight loss, new constipation or a change in bowel habit lasting more than 3 weeks — please do not dismiss it as পাইলস without a proper examination.
