Symptoms of Gastrointestinal (GI) Cancer

Gastrointestinal (GI) cancer can develop in different parts of the digestive system, and symptoms may vary depending on the location and stage of the cancer. Common symptoms may include:

• Abdominal pain.
• Feeling full in the upper abdomen after eating a small meal.
• Heartburn or indigestion.
• Nausea and vomiting.
• Poor appetite.
• Unexplained weight loss.
• Black-coloured or red blood in the stool.
• Constipation.

How Is GI Cancer Diagnosed?

Endoscopy and Colonoscopy

Endoscopy and colonoscopy allow doctors to visualize different parts of the gastrointestinal tract. These procedures can help identify abnormal areas, growths, or lesions and allow tissue samples (biopsies) to be collected for further examination.

Depending on the suspected type and location of cancer, additional investigations such as imaging scans and laboratory tests may also be recommended.

Treatment of GI Cancer

The treatment of gastrointestinal cancer depends on the type, location, stage, and other characteristics of the cancer, as well as the patient's overall health.

Surgery is an important treatment modality for many localized gastrointestinal cancers when the tumor can be safely removed.

Depending on the individual case, chemotherapy, targeted therapy, or radiation therapy may be recommended before or after surgery. These treatments may be used to shrink a tumor before surgery, reduce the risk of recurrence after surgery, or control cancer that cannot be treated with surgery alone.

Treatment of Advanced GI Cancer

In advanced or metastatic gastrointestinal cancers, treatment is generally focused on controlling the disease, relieving symptoms, maintaining quality of life, and extending survival. Depending on the cancer type and its specific characteristics, treatment may include chemotherapy, immunotherapy, targeted therapy, or combinations of these treatments.

The treatment approach for advanced GI cancer varies from person to person. Some advanced cancers may be treatable for prolonged periods, while others may not be curable. A medical oncologist can recommend an appropriate treatment plan based on the individual diagnosis and test results.

Conclusion

Gastrointestinal cancers can cause symptoms such as abdominal pain, indigestion, changes in appetite, unexplained weight loss, and blood in the stool. Endoscopy or colonoscopy, along with biopsy and other investigations, can help establish a diagnosis. Treatment may involve surgery, chemotherapy, radiation therapy, targeted therapy, or immunotherapy depending on the type and stage of the cancer.
