Is there any treatment for small bowel cancer? Answers gastro surgeon

Symptoms of small bowel cancer vary depending upon the type and severity of the tumour. So whenever you consult a GI surgeon, your doctor will ask you about your health conditions and conduct blood tests and imaging tests like endoscopy, CT scan and X-rays to identify the severity of your cancer.

The treatment you will be given will depend upon the stage of your cancer

  • Surgery

If small portion of your intestine gets affected, your cancer doctor will remove the part of the intestine that contains cancer and rejoin the cut ends of the intestine.

  • Chemotherapy

During this treatment, your doctor will use strong chemical drugs to destroy the cancer cells. Your doctor may also suggest chemotherapy to kill the remaining cancer cells

  • Radiation

Radiation therapy is prescribed when surgical methods fail to remove the cancer cells. This therapy uses high energy X-rays to kill the cancer and prevent them from growing.


If you are diagnosed with small bowel cancer, don’t panic. Early detection will help the doctors find the best possible treatment options depending upon the stage of your cancer.
