Small intestine cancer, also known as small bowel cancer, affects the small intestine, which is the part of the digestive system located between the stomach and the large intestine. Although this type of cancer is rare, it can be severe. The small intestine is responsible for digesting food and absorbing nutrients, so cancer in this area can lead to significant health issues. Symptoms of small intestine cancer can include stomach pain, unexplained weight loss, nausea, vomiting, and changes in bowel habits. Some people may also notice blood in their stool or experience jaundice, which causes the skin and eyes to turn yellow.
Doctors use various tests, such as imaging scans and biopsies, to diagnose small intestine cancer. Treatment often involves surgery to remove the tumour, along with chemotherapy to target any remaining cancer cells. Early detection is key, as it can significantly improve treatment outcomes. Observing unusual symptoms and having regular medical check-ups can help catch small intestine cancer early. Although rare, being aware of this type of cancer is essential for maintaining digestive health.
The signs and symptoms of small intestine cancer can resemble other digestive problems. Common symptoms include:
Abdominal pain or discomfort: Persistent pain or cramping in the stomach area.
Unexplained weight loss: Losing weight without trying.
Nausea and vomiting: Feeling sick or vomiting, especially after eating.
Changes in bowel habits: Diarrhoea, constipation, or changes in stool consistency.
Blood in stool: Dark or red blood may appear, indicating possible bleeding in the digestive tract.
Fatigue: Feeling extremely tired or weak without an apparent cause.
If you experience any of these symptoms, especially if they last, it's essential to see a doctor.
The exact causes of small intestine cancer are not fully understood, but several factors may contribute, including:
Genetic mutations: Changes in genes can raise cancer risk.
Inherited conditions: Disorders like familial adenomatous polyposis (FAP) and Lynch syndrome are associated with higher risks.
Chronic inflammation: Conditions like Crohn's disease can lead to long-term inflammation, increasing cancer risk.
Diet: A diet high in fat and low in fibre may raise the risk.
Smoking and alcohol: Both are linked to various cancers, including small intestine cancer.
Persistent digestive symptoms: If you experience ongoing abdominal pain, unexplained weight loss, or blood in your stool.
Severe nausea or vomiting: If it affects your ability to eat or drink.
Fatigue or weakness that does not improve with rest.
New or worsening symptoms: Any change in health that is concerning.
Several factors may increase your risk of developing small intestine cancer:
Age: More common in people over 60.
Family history: Having a family history of small intestine or other cancers increases risk.
Certain medical conditions: celiac disease, Crohn's disease, or Peutz-Jeghers syndrome.
Diet and lifestyle: High-fat diets and sedentary lifestyles can contribute.
To diagnose small intestine cancer, doctors may perform several tests:
Physical examination: Checking for abdominal swelling or tenderness.
Imaging tests:
CT scans offer detailed images of the abdomen to identify tumours.
MRI scans: These help view soft tissues in the small intestine.
X-rays: Can reveal blockages or other problems.
Endoscopy: Inserting a thin tube with a camera through the mouth or rectum to examine the small intestine and collect biopsies.
Biopsy: Removing a small tissue sample to check for cancer cells.
Blood tests: Used to detect anaemia or other indicators of cancer.
Do's:
Stay informed: Learn about your condition and treatment options.
Follow your doctor's advice: Attend all medical appointments and stick to your treatment plan.
Eat a balanced diet: Focus on nutritious foods to keep your strength.
Stay active: Engage in gentle physical activity as recommended by your doctor.
Seek support: Talk to friends, family, or support groups for emotional help.
Don'ts:
Don't ignore symptoms: Report any new or worsening symptoms to your doctor.
Avoid smoking and excessive alcohol: Both can increase cancer risk and interfere with treatment.
Don't skip follow-up appointments: Regular check-ups are essential for monitoring your health.
Don't rely solely on alternative treatments: Always consult your doctor before trying new therapies.
