Gastrointestinal (GI) Cancers

Gastrointestinal cancers begin in the lining of the digestive tract and related organs. These cancers can affect any part of the system—from the oesophagus to the intestines—and may also include the stomach, pancreas, liver, and bile ducts. Bowel and colorectal cancers are also classified under the GI cancer category.

These cancers occur when abnormal cells grow in an uncontrolled way and form a tumour, which can interfere with the normal function of the digestive system.

How is it Diagnosed?

The signs and symptoms of gastrointestinal cancers vary depending on the specific area involved. For example:

Oesophageal cancer may cause difficulty swallowing

Stomach cancer may lead to persistent reflux or indigestion

Pancreatic cancer could cause back pain or jaundice

Liver cancer may present as pain or swelling in the upper right side of the abdomen

Diagnosis may include a combination of:

Blood tests to check for liver function or tumour markers

Imaging such as CT, MRI or PET scans

Endoscopy to visualise the inside of the digestive tract

Biopsy to confirm if cancer cells are present

At SATH, these diagnostic services are coordinated with our on-site pathology and imaging partners for timely results and comprehensive care.

Treatment Options

Treatment for gastrointestinal cancers is tailored to the type and stage of the disease and may involve:

Surgical removal of the tumour

Chemotherapy

Targeted therapies or immunotherapy

Radiation therapy when appropriate

Treatment is coordinated by our multidisciplinary care team, which includes medical oncologists, surgeons, radiation oncologists, nurses, and allied health professionals. This team works together to develop a personalised plan for each patient.
