Colorectal Surgeon Mumbai: Expert Colon and Rectal Cancer Care by Dr. Ganesh Nagarajan
Colorectal cancer affects the colon or rectum and can develop with symptoms that are sometimes mistaken for common digestive problems. Persistent changes in bowel habits, blood in the stool, abdominal discomfort, unexplained weight loss, and fatigue should not be ignored. Early evaluation can help identify the cause and determine the most appropriate treatment.
If you are looking for a colorectal surgeon mumbai, Dr. Ganesh Nagarajan at Cancer Surgery Clinic offers specialized expertise in gastrointestinal (GI), hepatobiliary, and pancreatic cancer surgery, including the surgical management of colorectal malignancies. His approach combines detailed evaluation, individualized treatment planning, and consideration of advanced surgical techniques when clinically appropriate.
Understanding Colorectal Cancer
Colorectal cancer begins in the large intestine, which includes the colon and rectum. Although these organs are connected, the location and stage of a tumour influence how it is treated.
Colon cancer treatment often involves surgery to remove the affected section of the colon and nearby lymph nodes. Depending on the stage and other tumour characteristics, chemotherapy may also be recommended.
Rectal cancer requires particularly careful planning because the rectum lies within the pelvis, close to nerves and muscles involved in bowel control. Some patients may need chemotherapy and radiation before surgery to help reduce the tumour and improve treatment outcomes.
A personalized treatment plan is essential because no two colorectal cancer cases are exactly alike.
Symptoms That Need Medical Attention
Colorectal cancer can present with several symptoms, although these may also occur with non-cancerous conditions. Persistent or unexplained symptoms should be assessed by a qualified medical professional.
Common warning signs include:
Blood in or on the stool
Constipation, diarrhoea, or a lasting change in bowel habits
Recurrent abdominal pain, cramps, or bloating
A feeling that the bowel has not emptied completely
Unexplained weight loss or reduced appetite
Persistent fatigue or weakness, sometimes associated with anaemia
Rectal discomfort, urgency, or changes in stool appearance
Having these symptoms does not automatically mean a person has cancer. However, timely investigation is important, especially for people with a family history of colorectal cancer, a history of polyps, or certain inflammatory bowel conditions.
How Is Colorectal Cancer Diagnosed?
Accurate diagnosis helps the specialist understand the tumour’s location, type, and extent before recommending treatment.
Colonoscopy and biopsy: Colonoscopy allows the doctor to examine the colon and rectum. If an abnormal growth is found, a tissue sample may be collected for laboratory analysis.
Imaging investigations: CT scans help assess whether the disease has spread to other areas. MRI is particularly useful for evaluating the local extent of rectal cancer. Other tests may be recommended depending on the individual case.
Staging and treatment planning: Once the findings are available, the medical team determines the stage of the cancer and considers the appropriate treatment sequence. Surgery, chemotherapy, and radiation may be used individually or in combination, depending on the diagnosis.
Treatment Options for Colon and Rectal Cancer
Treatment depends on the tumour’s location, stage, size, and relationship with surrounding structures, as well as the patient’s overall health.
1. Colectomy for Colon Cancer
A colectomy involves removing part or, in selected cases, all of the colon. The affected bowel segment and relevant surrounding lymph nodes are removed to achieve appropriate cancer clearance. The remaining healthy bowel may then be reconnected when it is safe and suitable.
The exact operation may be called a partial colectomy, segmental resection, or hemicolectomy, depending on the portion of the colon involved.
2. Surgery for Rectal Cancer
Rectal cancer surgery varies according to the tumour’s position and extent. Some selected early cancers may be suitable for local excision. Other patients may need procedures such as low anterior resection or abdominoperineal resection.
Where possible, the treatment plan considers preservation of bowel function and the muscles responsible for continence. Some operations require a temporary or permanent stoma, depending on the tumour and surgical findings. The surgeon should explain the likely options before treatment.
3. Laparoscopic and Robotic Surgery
For suitable patients, laparoscopic or robotic-assisted surgery may be an option. These approaches use smaller incisions and specialized instruments to remove the tumour.
Robotic surgery provides magnified vision and articulated instrument movement, which can be particularly useful when operating in the confined pelvic space. Potential benefits of minimally invasive approaches may include smaller incisions, less wound-related discomfort, and a shorter recovery period in appropriate cases.
However, robotic or laparoscopic surgery is not suitable for every tumour. The priority is safe, complete cancer removal, and the surgical approach should be selected according to the patient’s needs rather than the technology alone.

What to Expect During a Consultation
During a consultation, bring previous reports, colonoscopy findings, biopsy results, imaging scans, and a list of current medications. The specialist will review the available information, ask about symptoms and medical history, and explain whether additional investigations are needed.
Patients who have already received a cancer diagnosis can discuss the stage of the disease, the purpose of the proposed operation, possible risks, recovery expectations, and whether additional treatment may be required. A second opinion can also be helpful when a diagnosis or treatment plan is complex.
Choosing a colorectal surgeon mumbai means looking beyond the procedure itself. Consider the surgeon’s relevant experience, the treatment options available, communication with the care team, and the plan for follow-up and recovery.
