The small intestine is the longest part of the GIT. Any uncontrolled growth in the small intestine is cancer in that part. Cancers of the small intestine are rare.
The small intestine has three parts:
Because the intestine stretches easily, small lumps can sit there quietly without causing trouble for months. If you catch it early, removing the growth gives the best chance to cure.
The exact cause is not always known, but certain factors may increase the risk:
Many people who get these tumors have none of these risk factors.
Before planning an operation, your surgeon checks how deep the tumor has reached:
Small tumors are usually asymptomatic. Symptoms appear when they block the bowel or bleed.
Surgery is the mainstay of treatment.
Operating through small keyhole cuts makes a huge difference. Robotic tools give surgeons clear 3D vision and wristed instruments that turn smoothly in tight spaces. This level of control cuts down on bleeding, protects healthy tissue, means less pain after surgery, and helps your bowels wake up and work sooner.
Depending on the biopsy results, surgery is often backed by cancer medications:
Recovery after surgery is usually fast. Patients walk the next day and are home within a few days. Routine checkups, blood tests, and scans make sure your nutrition stays on track and any recurrence is spotted right away.
When operating on small intestine tumors, our focus is taking the mass out cleanly while protecting your normal digestion and nutrient absorption. Because these growths can be tricky to find, many patients come to us with vague belly ache or low iron that was overlooked for months. Using high-definition robotic tools lets us take out the tumor and surrounding lymph nodes through small incisions without disturbing nearby blood vessels. Most of our patients are up and walking right away, eating soft meals, and ready to go home in 3 to 4 days.
You might just feel a bit off: mild cramps after eating, feeling bloated, mild nausea, losing weight without trying, or feeling unusually tired because your iron levels have dropped.
Not very often at all. It is much less common than cancers of the colon, rectum, or stomach.
You will likely have a CT scan, swallow a tiny camera pill (capsule endoscopy), or have a specialist look inside with a long flexible scope to take a small tissue sample.
If the tumor has not spread, having an experienced surgeon cut it out completely alongside the nearby lymph nodes is the most effective approach.
The surgeon removes the diseased piece of intestine and its lymph nodes, then stitches the healthy ends back together so your food can move normally.
No. In the majority of cases the healthy ends of bowel are joined together.
Yes. If you catch it early and remove the whole growth cleanly, many people go on to live cancer-free lives.
It depends on the stage of the tumor.
See a specialist if you have lasting belly pain, dark blood in your stool, repeated bowel blockages, low iron that will not budge, or an unexplained lump seen on a scan.
