You notice persistent stomach discomfort, unexplained weight loss, difficulty swallowing, blood in your stool, or a change in your bowel habits. Tests are done, and suddenly the word “cancer” enters the conversation.

Naturally, the next question is: “Do I need a GI Cancer Surgeon?”

A GI cancer surgeon specialises in surgical treatment of cancers affecting the digestive system. This can include cancers of the stomach, oesophagus, colon, rectum, liver, pancreas, and other gastrointestinal organs.

What Does a GI Cancer Surgeon Do?

GI cancer surgery is more specialised than routine abdominal surgery because cancer treatment may involve removing the tumour along with surrounding tissue and, in some cases, nearby lymph nodes.

A surgeon also works as part of a wider cancer-care team when appropriate. Treatment may involve surgery, chemotherapy, radiation, targeted treatment, immunotherapy, or a combination of approaches depending on the cancer.

Main Specialties

Our main specialties may include:

• Stomach cancer surgery

• Colorectal cancer surgery

• Oesophageal cancer surgery

• Liver cancer surgery

• Pancreatic cancer surgery

• Gallbladder and bile-duct cancer surgery

• Laparoscopic GI cancer surgery

• Complex abdominal cancer surgery

• Lymph-node assessment and removal

• Multidisciplinary cancer treatment planning

The exact approach depends on the type, location, stage, and characteristics of the cancer.

Don't Let the Word “Cancer” Rush Your Decisions

A cancer diagnosis can make people feel that everything has to happen immediately.

Some cancers do require prompt treatment, but rushing without understanding the diagnosis can also leave patients confused about their options.

Before treatment, ask your medical team about the pathology report, stage, treatment goals, available approaches, and whether additional scans or specialist opinions are needed.

Understand the Diagnosis First

A suspicious scan does not always provide the complete picture.

A biopsy and pathology assessment may be needed to identify the exact type of cancer. Staging investigations can then help determine whether surgery is appropriate and how it fits into the overall treatment plan.

GI Cancer Surgery Is Becoming More Sophisticated

Surgical treatment for gastrointestinal cancers has developed considerably, with open, laparoscopic, and robotic approaches available for selected patients and procedures.

The appropriate technique depends on the cancer and the surgeon's assessment. Minimally invasive surgery is not automatically suitable for every tumour.

A 2024 global cancer analysis estimated approximately 20 million new cancer cases worldwide in 2022, with cancer remaining a major global health burden. The figures reinforce the importance of early evaluation and coordinated cancer care, but they do not predict the outcome for any individual patient.

A Real-World Scenario

Consider a patient who has experienced unexplained weight loss and persistent stomach discomfort for several months. Investigations eventually identify a stomach tumour.

Instead of immediately searching for an operation, the patient undergoes appropriate staging and specialist evaluation. The cancer team then determines whether surgery, systemic treatment, radiation, or a combination should come first.

The important lesson is simple: cancer surgery should be planned around the cancer—not around the patient's fear of the diagnosis.

The Contrarian Advice: Don't Judge Surgery by the Size of the Incision

Patients often assume that robotic or laparoscopic surgery must be better because the cuts are smaller.

That is too simplistic.

For cancer surgery, the priority is appropriate cancer treatment and safe removal of the disease. In some cases, minimally invasive surgery may be suitable. In others, open surgery may provide the appropriate access.

The surgical approach should be determined by the tumour, anatomy, stage, previous treatments, and the expertise available.

Questions Worth Asking Your Surgeon

Before treatment, consider asking:

• What type and stage of cancer do I have?

• Is surgery necessary?

• What is the goal of the operation?

• Will I need chemotherapy or radiation?

• Is laparoscopic or robotic surgery appropriate?

• How much of the digestive organ needs to be removed?

• What will recovery look like?

• What are the possible complications?

Getting clear answers can make the treatment journey easier to understand.

Dr. Sanjay Verma: Care That Starts With Understanding

Dr. Sanjay Verma represents the patient-centred approach people often seek when facing complex surgical decisions. A consultation should give patients an opportunity to understand their diagnosis, treatment options, surgical goals, possible risks, expected recovery, and the role of other cancer treatments before proceeding.

Recovery Depends on the Cancer Operation

There is no universal recovery period for GI cancer surgery.

A smaller laparoscopic procedure and a major stomach, bowel, liver, or pancreatic operation can have very different recovery timelines. Hospital stay, diet, activity levels, wound care, and follow-up will depend on the procedure performed.

Cancer treatment may also continue after surgery. Follow-up appointments and additional therapy may be recommended based on the final pathology and the overall treatment plan.

Frequently Asked Questions

What does a GI cancer surgeon treat?

A GI cancer surgeon treats cancers affecting parts of the digestive system, including the stomach, oesophagus, colon, rectum, liver, pancreas, gallbladder, and bile ducts.

Is surgery always required for gastrointestinal cancer?

No. Treatment depends on the type and stage of cancer and the individual patient's circumstances. Surgery may be combined with chemotherapy, radiation, targeted therapy, immunotherapy, or other treatments.

Should I get a second opinion before cancer surgery?

A second opinion can help you better understand the diagnosis and available treatment approaches, particularly when surgery is complex or multiple treatment options are being considered.

Focus on the Next Right Step

A GI cancer diagnosis can feel overwhelming, but you do not have to understand the entire treatment journey in one day.

If you or a family member has been diagnosed with gastrointestinal cancer or has a suspicious finding requiring specialist evaluation, consult a qualified GI Cancer Surgeon in Saket and discuss the diagnosis, staging, treatment options, and surgical plan carefully.

Speak with Dr. Sanjay Verma, bring your pathology reports and scans, and make sure you understand the proposed treatment before moving forward.
