Small Intestine, Large Intestine — Understanding Which Part Is Affected

The intestines are the long tube through which food passes after leaving your stomach. They have two main sections — and cancers in each behave very differently:

• The small intestine — about 5 to 6 metres long; divided into three parts (the duodenum just after the stomach, the jejunum in the middle, and the ileum at the end). It absorbs most of the nutrients from digested food. Cancer here is rare — it makes up only about 1 to 3% of all bowel cancers — but it includes several very different types that are often diagnosed late because they are so hard to spot.
• The large intestine (colon) — the shorter, wider section that absorbs water before waste passes out of the body. Colon cancer is one of the most common cancers in the world and in India, and is much better understood than small bowel cancer.
• The rectum — the last 12 to 15 centimetres before the anus. Rectal cancer shares risk factors with colon cancer but is treated very differently. CION has a dedicated rectal cancer treatment page with full information on that pathway.

Some intestinal cancers are straightforward to diagnose; others can hide undetected for years because the area they grow in cannot be seen by a standard camera examination. The right diagnostic pathway — and the right treatment — depends entirely on which part of the intestine is affected.

What Increases the Risk of Intestinal Cancer?

Risk Factors for Small Intestine Cancer

Unlike colon cancer, small intestine cancer is not mainly linked to diet. The biggest risk factors are conditions that cause long-term inflammation or irritation of the small bowel lining, and inherited family conditions that affect the whole digestive tract:

• Crohn's disease — a long-term inflammatory bowel condition that significantly raises the risk of cancer in the small intestine, particularly in the last section (the ileum).
• Celiac disease — an immune reaction to gluten that damages the small intestine; if left untreated for years, it is associated with a rare type of bowel lymphoma (a cancer of the immune cells lining the gut).
• Lynch syndrome — an inherited condition caused by a faulty gene that runs in families; it significantly increases the lifetime risk of cancers in both the small bowel and the colon. A simple blood test can check for the faulty gene.
• Familial Adenomatous Polyposis (FAP) — an inherited condition causing hundreds of polyps (small growths) to develop throughout the bowel, particularly in the colon but also in the first part of the small intestine (the duodenum). These polyps can turn cancerous if not monitored and removed.
• Peutz-Jeghers syndrome — a rare inherited condition causing polyps to grow throughout the small and large intestine; also causes distinctive brown spots on the lips and inside the mouth. People with this condition need regular bowel monitoring from a young age.

Risk Factors for Colon Cancer

• Diet high in red and processed meat (beef, lamb, sausages, bacon) and low in fibre — consistently linked to higher colon cancer risk.
• Being overweight, inactive, or spending most of the day sitting.
• Long-term inflammatory bowel disease — ulcerative colitis or Crohn's disease that affects the large intestine.
• Bowel polyps — small benign growths in the colon lining; most colon cancers begin this way over many years; colonoscopy finds and removes them before they turn cancerous.
• A close family member (parent, sibling, or child) who has had colon cancer.
• Lynch syndrome and FAP — inherited conditions causing a very high lifetime colon cancer risk.
• Being over 50 years old — risk increases significantly with age; colonoscopy screening is recommended from this age.
• Smoking and drinking alcohol heavily over many years.

If you have a family member diagnosed with colorectal cancer — particularly before age 60 — speak to a CION oncologist about genetic testing for Lynch syndrome. Identifying this hereditary condition can guide screening for you and other family members before cancer develops.

What Are the Warning Signs of Intestinal Cancer?

The symptoms depend on which part of the intestine is affected. Many overlap with far more common and less serious conditions — which is one reason both types of intestinal cancer can be missed early on.

Small Intestine Cancer Warning Signs

• Stomach cramping or pain that keeps coming back — often vague, around the middle of the abdomen.
• Feeling sick (nausea) and vomiting — particularly if the cancer has grown large enough to partially block the bowel.
• Blood in the stool — may appear as dark red blood or as very dark, tarry-looking stools from bleeding higher up in the gut.
• Unexplained weight loss — losing weight without trying, often alongside a drop in appetite.
• Tiredness and weakness from anaemia — slow bleeding from a tumour can cause a low blood count that leaves patients feeling permanently exhausted even without visible bleeding.
• Yellowing of the skin and eyes (jaundice) — specifically for cancers that grow near the opening where the bile duct enters the small intestine, which can block the flow of bile.
• Flushing, loose stools, and stomach cramps — sudden redness of the face and neck can be a sign of a type of small intestine cancer called a neuroendocrine tumour, which releases hormones into the bloodstream.

Colon Cancer Warning Signs

• A persistent change in your bowel habits — diarrhoea, constipation, or stools that are narrower than usual, lasting more than 2 to 4 weeks.
• Blood in or on the stool.
• Persistent bloating, gas, or stomach discomfort.
• Feeling that your bowel has not emptied completely after a motion.
• Unexplained weight loss and tiredness.
• Anaemia (a low blood count) without an obvious cause — from slow, hidden bleeding from a tumour.

Why Small Intestine Cancer Is Hard to Find — And How We Find It

Colon cancer is relatively straightforward to diagnose: a camera examination of the large bowel (colonoscopy) can see the entire colon, and a small tissue sample is taken at the same time. Small intestine cancer is far harder to detect — and this is why it is so often found late.

A standard stomach camera reaches only the very first section of the small intestine. A standard colonoscopy reaches the colon and only a very short section of the last part of the small intestine. The 5 to 6 metres in between — where most small bowel cancers grow — cannot be seen by either. Two specialist tools bridge this gap:

Swallowing a Camera Pill (Capsule Endoscopy)

The patient swallows a small capsule — about the size of a large vitamin tablet — that contains a tiny camera and a transmitter. As the capsule travels naturally through the small intestine over the course of the day, it takes thousands of photographs of the bowel lining, which are transmitted wirelessly to a recording device worn on the patient's belt. The images are reviewed by a specialist who looks for any suspicious lesion, area of bleeding, or abnormal growth. The process is painless, does not require sedation, and the capsule passes naturally.

Getting a Sample from the Small Bowel (Double Balloon Enteroscopy)

When the camera pill identifies a suspicious area, a second specialist procedure is used to actually reach that part of the small intestine, look at it directly, and take a tissue sample for testing. This uses a specially designed flexible tube with two small balloons that grip the bowel wall and allow the scope to be pushed progressively deeper — from either the mouth or the rectum — until the target area is reached. It is done under sedation and allows the doctor to take a biopsy from any location in the small bowel. It is currently the best available tool for confirming small intestine cancer.

A Specialised CT Scan

A specially designed CT scan, taken after the patient drinks a large amount of liquid that fills and expands the small bowel, gives doctors a detailed image of the small intestinal wall. This helps identify tumour masses, check nearby lymph nodes, and assess whether the cancer has spread.

Diagnosing Colon Cancer

Colon cancer diagnosis is more straightforward: a colonoscopy camera examines the entire colon and takes a tissue sample from any suspicious area. A CT scan of the chest and abdomen checks whether cancer has spread. A blood test called CEA — which measures a substance that colon cancer cells release into the bloodstream — helps monitor how well treatment is working and checks for recurrence after surgery.

The Four Main Types of Small Intestine Cancer

Small intestine cancer is not one disease — it is four distinct conditions that happen to grow in the same part of the body. Getting the right treatment depends on correctly identifying which type is present from the pathology report.

Treatment for Small Intestine Cancer at CION

Surgery

Surgery is the only way to cure small intestine cancer that has not spread beyond the bowel. CION's surgical oncology team performs the right operation based on where the cancer is located:

• For cancers in the middle or lower small intestine — the affected section of bowel is removed along with a clear margin of healthy bowel on each side and the nearby lymph nodes. The two remaining ends of the intestine are then joined back together. Depending on the patient, this can be done through a large incision or through smaller keyhole cuts (laparoscopically).
• For cancers in the first section of the small intestine (the duodenum) — this area is very close to the head of the pancreas and the bile duct opening, so a more complex operation called a Whipple procedure is usually required. This is the same operation performed for pancreatic cancer in that area, and it involves removing the duodenum, the head of the pancreas, part of the bile duct, and the gallbladder, before reconnecting the digestive system. It is one of the most complex abdominal operations performed in oncology and requires an experienced surgical oncology team.

Chemotherapy After Surgery

After surgery, chemotherapy is recommended for patients with higher-risk tumours — where the cancer had grown through the full thickness of the bowel wall, or where nearby lymph nodes were involved. A combination of chemotherapy medicines is given as a drip every two weeks (FOLFOX), or as a similar combination where one of the medicines is an oral tablet taken at home (CAPOX). The aim is to destroy any microscopic cancer cells that may have been left behind and reduce the chance of the cancer coming back. CION's medical oncology team delivers this in a comfortable day-care setting, with regular monitoring throughout.

Treatment for Slow-Growing Neuroendocrine Tumours (NETs)

• Surgery — the first treatment for tumours that can be removed; even when the cancer has spread to the liver, removing as much of it as possible helps control hormone symptoms and improves survival.
• Monthly injections (octreotide or lanreotide) — for tumours that cannot be fully removed or that have spread; these once-monthly injections keep hormone symptoms under control (stopping or dramatically reducing flushing and diarrhoea) and slow the tumour's growth. Many patients remain on them for years with a good quality of life.
• Everolimus — a daily tablet that slows tumour growth further; used when the monthly injections alone are no longer sufficient.
• Targeted radiation treatment — for patients whose tumour cells have specific receptors on their surface, a specialist treatment can deliver radioactivity directly to tumour cells wherever they are in the body; arranged through CION's specialist referral network.

Colon Cancer Treatment at CION

Colon cancer — cancer of the large intestine — is one of the most treatable gastrointestinal cancers when found early. CION's colorectal oncology team manages all stages of colon cancer.

Surgery to Remove Colon Cancer

Surgery is the main treatment for colon cancer that has not spread to distant organs. The operation involves removing the section of colon containing the tumour along with a healthy margin on each side and the nearby lymph nodes, then reconnecting the remaining colon. The type of operation depends on which part of the colon is affected.

• Keyhole (laparoscopic) surgery — the preferred approach for eligible patients; smaller cuts, less pain, faster recovery, and equivalent cancer outcomes to open surgery.
• Open surgery — used when the cancer is large, in a difficult location, or when a previous abdominal surgery makes keyhole access more complex.
• Emergency stenting — for patients with a blocked colon caused by cancer; a small metal tube is placed inside the bowel to open the blockage, avoiding emergency surgery and allowing the patient to be stabilised before a planned operation.
• Removal of the entire large bowel — occasionally needed for patients with an inherited condition causing cancer throughout the colon (such as FAP or Lynch syndrome) or for cancers in multiple sites.

Chemotherapy and Targeted Treatment for Colon Cancer

After surgery for more advanced colon cancer, a 6-month course of chemotherapy (given as a drip every 2 weeks or as tablets combined with a shorter drip) significantly reduces the chance of the cancer coming back. For colon cancer that has spread to other organs — most commonly the liver or lungs — chemotherapy is the main ongoing treatment, often combined with a targeted medicine chosen based on a molecular test done on the tumour tissue.

• Molecular testing of the tumour — a test done on the tissue removed by surgery or biopsy; it checks for specific gene changes that determine which additional medicines are likely to work. Patients whose tumour does not carry a certain gene change can benefit from a targeted medicine that blocks cancer cell growth signals. Patients whose tumour shows a defect in how its DNA repairs itself (MSI-H/dMMR) may respond very well to immunotherapy rather than standard chemotherapy.
• Anti-blood vessel medicines — added to chemotherapy to cut off the blood supply the tumour needs to grow.
• Immunotherapy — for the specific group of patients whose tumour carries a DNA repair defect; this has been shown to work better than standard chemotherapy as a first treatment in this group.

For rectal cancer specifically — including the decision about whether chemotherapy and radiation are given before surgery, and whether surgery can be avoided entirely in some patients — see CION's dedicated Rectal Cancer Treatment page.

Is Your Bowel Cancer Hereditary? — Protecting Your Family

A meaningful proportion of intestinal cancers — both small bowel and colon — run in families because of inherited gene changes. At CION, we offer genetic testing to patients who are diagnosed with bowel cancer at a young age, have had multiple bowel cancers, or have several family members affected. If a hereditary condition is confirmed, close family members can be tested and monitored — sometimes catching cancer early enough to prevent it altogether.

• Lynch syndrome — the most common hereditary bowel cancer condition; caused by a faulty gene inherited from a parent; significantly raises lifetime risk of colon cancer, small bowel cancer, and several other cancers. A simple test of the tumour tissue can flag this at the time of diagnosis, after which a blood test confirms whether the gene fault is inherited. Family members who carry the gene can start regular bowel camera monitoring years earlier than the general population.
• Familial Adenomatous Polyposis (FAP) — causes hundreds of small polyp growths in the colon from early adulthood; without management, these almost always become cancerous. Also causes polyps in the first part of the small intestine that need monitoring. People with FAP are usually identified in childhood or early adulthood through family testing.
• Peutz-Jeghers syndrome — causes multiple polyps throughout the intestinal tract, together with distinctive dark spots on the lips and inside the mouth; requires lifelong monitoring of the bowel at specialist centres.
• Celiac disease — not a genetic cancer syndrome in itself, but long-standing untreated celiac disease is associated with a small increased risk of a rare type of intestinal lymphoma; the risk largely disappears with strict adherence to a gluten-free diet.

If you have been diagnosed with bowel cancer before the age of 50, if multiple family members have had bowel or related cancers, or if you have one of the conditions above, speak to a CION oncologist about genetic counselling and testing for yourself and your family.

Every Case Reviewed by a Team Before Treatment Begins

Intestinal cancer covers a wide range of very different diseases. The treatment decisions — particularly for small intestine cancer, where the type of cancer fundamentally changes the treatment — require specialist input from surgeons, medical oncologists, and gastroenterologists together. At CION, every case is reviewed by our multidisciplinary team before any recommendation is made:

• Identifying the exact type of small intestine cancer from the pathology report — each type has a completely different treatment plan.
• Arranging a camera pill examination and specialist bowel scope for lesions that cannot be reached by standard endoscopy.
• Choosing the right surgical approach — standard bowel resection or the more complex Whipple procedure for cancers in the first part of the small intestine.
• Molecular testing of the tumour to identify which chemotherapy and targeted medicines will work best.
• Monthly injection therapy for slow-growing neuroendocrine tumours — managing symptoms and slowing tumour growth.
• Genetic testing offered to appropriate patients and discussion of family screening implications.
• Colon cancer staging and chemotherapy sequencing across the multidisciplinary team.
• Link to CION's Rectal Cancer Treatment pathway for rectal-specific cases.
• NCCN and ESMO evidence-based protocol alignment across all subtypes.
• Digital coordination across all 7 Hyderabad locations.
