Rectal cancer signs & symptoms | Guide for Bangladeshi patients
Rectal cancer is a serious illness that starts in the rectum, the last part of the large intestine. Like many other cancers, spotting it early can make a huge difference in how well the treatment works. In Bangladesh, many people first
think it’s “piles” or simple constipation or dysentery and delay a check-up. That delay matters. In 2022, about 5,700 Bangladeshis were diagnosed with cancers of the colon and rectum. The problem is, many people confuse the early
signs with common issues like piles, constipation or gas and don’t seek help in time. By knowing the warning signs, you can take action sooner and get the right care.
In this blog, we’ll walk you through the common signs and symptoms of rectal cancer, how they might show up in daily life, and why you should never ignore them. We will also share when to see a specialist and how early diagnosis can
truly save lives.
Rectal cancer occurs when cells in the lining of the rectum begin to grow out of control. Over time, they can form a lump or tumor and may spread to other parts of the body. Anyone can develop rectal cancer,
but the chances are higher if you are over 40, have a family history of colorectal disease, or have long-term bowel problems like ulcerative colitis or Crohn’s disease.
Common signs & symptoms of rectal cancer
Noticing the early warning signs of rectal cancer can make a big difference in treatment success. Many symptoms can seem like simple digestive issues, but they shouldn’t be ignored. Here are the most common signs to watch for and discuss
with your doctor.
Changes in bowel habits: Ongoing constipation, diarrhea, or a feeling that your bowel isn’t fully empty after passing stool.
Blood in the stool: Bright red blood on toilet paper or dark, tar-like stools.
Narrow or ribbon-shaped stools: Stools that look thinner than usual.
Persistent abdominal discomfort: Cramping, bloating, or lower belly pain that doesn’t go away.
Unexplained weight loss: Losing weight without changing your diet or exercise routine.
Ongoing fatigue or weakness: Often caused by anemia from slow internal bleeding.
A lump or fullness in the rectal area: Sometimes noticed during cleaning or medical check-ups.
Causes of rectal cancer
Rectal cancer happens when healthy cells in the rectum change and start growing out of control. Over time, these cells can form a lump (tumor) and may spread to other parts of the body. While the exact cause isn’t always clear, certain
factors can increase the risk:
Genetic changes: Inherited gene mutations passed down in families.
Family history: Having close relatives with colorectal cancer or polyps.
Unhealthy diet: Eating a lot of processed meat and very little fiber.
Inflammatory bowel diseases: Long-term conditions like ulcerative colitis or Crohn’s disease.
Lifestyle factors: Smoking, heavy alcohol use, lack of exercise, and obesity.
Age: Risk increases after age 40, though it can occur earlier.
Rectal cancer treatment in Bangladesh
Rectal cancer treatment in Bangladesh has advanced greatly in recent years, offering patients access to modern techniques and expert care. The right treatment depends on the stage of the cancer, overall health, and individual needs.
In most cases, a combination of surgery, medication, radiotherapy and supportive care is used to achieve the best results.
Common treatment options include:
Surgery: The main treatment for most rectal cancers aims to remove the tumor and affected tissue.
Radiation therapy: Often used before or after surgery to shrink tumors and reduce recurrence risk.
Chemotherapy: Uses medicine to destroy cancer cells or stop them from spreading.
Targeted therapy: Newer drugs that attack specific cancer cell changes, used in certain cases.
Palliative care: Helps manage symptoms and improve quality of life for advanced stages.

Consult with a colorectal surgeon in Bangladesh
If you notice rectal bleeding, a change in bowel habit, or persistent anal pain, don’t wait it out. For piles, fissure, fistulas, rectal cancer evaluation, and advanced minimally invasive treatment, you can book a consultation
with Prof. Dr. Tariq Akhtar Khan, a master colorectal surgeon with extensive experience in Bangladesh. Appointments are patient-friendly, private, and handled with dignity.
No. Piles are common, but bleeding can also come from fissures, infections, polyps, or rectal cancer. If bleeding lasts more than a few days, keeps coming back, or comes with weight loss, weakness, or bowel habit change—see a colorectal surgeon.
Book a visit if you have bleeding, new constipation/diarrhea for 2–3 weeks, pencil-thin stools, persistent pain, mucus discharge, or a family history of colorectal cancer. Go urgently if bleeding is heavy, you feel faint, or you can’t pass stool/gas.
Yes. Many Bangladeshi patients present in their 20s–40s. Don’t wait because of age. Any ongoing bleeding or bowel change needs a proper check-up and, if advised, a colonoscopy.
Treatment depends on stage and location: surgery (often minimally invasive), plus radiotherapy and/or chemotherapy when needed. Early cases may avoid major surgery.
