Rectal Cancer Treatment in Delhi
Expert Evaluation, Staging & Personalized Treatment for Rectal Cancer
Rectal cancer is a cancer that develops in the tissues of the rectum, the lower part of the large intestine. Symptoms can include blood in the stool, changes in bowel habits, abdominal discomfort, unexplained weight loss, and fatigue.
Because the rectum is located close to important pelvic structures, accurate staging and careful treatment planning are particularly important.
Dr. Sri Aurobindo Prasad Das, specialist in Surgical Gastroenterology and Liver Transplantation, provides comprehensive evaluation and personalized treatment planning for patients with suspected or diagnosed rectal cancer.
Get your reports reviewed and understand the appropriate treatment options for your condition.
What Is Colon Cancer?
Rectal cancer develops when abnormal cells in the lining or tissues of the rectum grow uncontrollably and form a tumor.The rectum is the final portion of the large intestine and plays an important role in storing stool before it leaves the body.Rectal cancer may be localized to the rectum or may involve nearby lymph nodes or distant organs.
Treatment depends on several factors, including:
- Location of the tumor
- Size and extent of the tumor
- Depth of invasion
- Lymph node involvement
- Whether the cancer has spread
- Relationship of the tumor to the anal sphincter
- Molecular and pathological characteristics
- Overall health of the patient
Symptoms of Rectal Cancer
Rectal cancer can cause symptoms such as:
Blood in the stool
Rectal bleeding
Constipation or diarrhoea
Narrower-than-usual stools
Abdominal pain or cramps
Persistent bloating
Unexplained weight loss
Loss of appetite
Fatigue or weakness
Unexplained anemia
When Should You Consult a Specialist?
Consider specialist evaluation if you have:
Blood in the stool or rectal bleeding
Persistent changes in bowel habits
Unexplained weight loss
Recurrent abdominal or rectal discomfort
Unexplained anemia
Persistent constipation
A feeling of incomplete bowel emptying
A biopsy confirming rectal cancer
How Is Rectal Cancer Diagnosed?
A combination of examinations, endoscopy, biopsy, and imaging may be required.
Digital Rectal Examination
Colonoscopy
Biopsy
MRI of the Pelvis
CT Scan
CEA Blood Test
Colon Cancer Staging
Staging determines how far the cancer has progressed.
Doctors generally evaluate:
T – Primary Tumor
How deeply the tumor has grown through the rectal wall and into surrounding tissues.
N – Lymph Nodes
Whether nearby lymph nodes contain cancer cells.
M – Metastasis
Whether the cancer has spread to distant organs such as the liver or lungs.
Rectal Cancer Treatment
There is no single treatment suitable for every patient.
Treatment is individualized according to:
- Cancer stage
- Tumor location
- Tumor size
- Relationship to the anal sphincter
- Lymph node involvement
- Molecular characteristics
- Whether the cancer has spread
- Overall health of the patient
Treatment may include:
- Surgery
- Chemotherapy
- Radiation therapy
- Chemoradiation
- Total neoadjuvant therapy (TNT) in selected patients
- Targeted therapy
- Immunotherapy for selected tumors
- Active surveillance in carefully selected situations
Rectal Cancer Surgery
Surgery remains an important part of treatment for many patients with rectal cancer. The type of surgery depends on the tumor's location, stage, size, involvement of surrounding structures, and response to preoperative treatment.
Local Excision
Selected early-stage tumors may be removed through the anus without a major abdominal operation.
This approach is suitable only for carefully selected tumors.
Low Anterior Resection
Low anterior resection (LAR) removes the cancer-containing portion of the rectum while attempting to preserve the anal sphincter when medically appropriate.
The remaining bowel may then be connected to the remaining rectum or anus.
Total Mesorectal Excision
Total mesorectal excision (TME) is an important surgical technique for many rectal cancers. It involves careful removal of the rectum and surrounding mesorectal tissue containing relevant lymphatic structures.
The exact procedure depends on the location and stage of the tumor.
Abdominoperineal Resection
For some low rectal tumors, particularly when the anal sphincter or nearby structures are involved, abdominoperineal resection (APR) may be required.
This operation involves removal of the rectum and anus and requires a permanent colostomy. The need for this procedure is determined after detailed assessment and staging.
Chemotherapy for Rectal Cancer
Chemotherapy uses anti-cancer medicines to destroy or control cancer cells. It may be used:
Before Surgery
Chemotherapy may be given before surgery, sometimes together with radiation therapy, to shrink or control the tumor and treat potential microscopic disease.
After Surgery
Chemotherapy may be recommended after surgery depending on the stage and treatment already received.
As Part of Total Neoadjuvant Therapy
For selected locally advanced rectal cancers, chemotherapy and radiation may be administered before surgery as part of a treatment strategy called total neoadjuvant therapy (TNT).
Radiation Therapy for Rectal Cancer
Radiation therapy is used more frequently in rectal cancer than in colon cancer.
It may be given before surgery, often together with chemotherapy, to reduce the risk of local recurrence and help make certain tumors easier to remove.
Radiation may also be used in selected patients after surgery or to relieve symptoms caused by advanced disease.
Total Neoadjuvant Therapy (TNT)
Potential goals include:
- Treating microscopic disease early
- Reducing the size or extent of the primary tumor
- Improving the possibility of complete tumor removal
- Helping determine how the tumor responds to treatment
- Potentially improving local disease control
Immunotherapy & Targeted Treatment
Some rectal cancers have molecular characteristics that can influence treatment.
Depending on pathology and biomarker testing, selected patients may be considered for:
- Immunotherapy
- Targeted therapy
- Other systemic treatments
For example, tumors with certain mismatch repair or microsatellite instability characteristics may respond differently to immunotherapy.
Treatment should be selected based on the individual’s pathology, molecular profile, cancer stage, and previous treatment.
Treatment for Advanced Rectal Cancer
When rectal cancer spreads to distant organs such as the liver or lungs, treatment becomes more complex.Depending on the extent and location of metastatic disease, treatment may include:
- Chemotherapy
- Targeted therapy
- Immunotherapy for selected patients
- Radiation therapy
- Surgery in carefully selected cases
- Local treatment of metastatic disease
- Procedures to control bleeding or obstruction
- Supportive and palliative care

Frequently Asked Questions
Warning signs can include rectal bleeding, blood in the stool, persistent changes in bowel habits, narrower stools, abdominal discomfort, unexplained weight loss, fatigue, and a feeling of incomplete bowel emptying. These symptoms can also occur with other conditions.
The possibility of successful treatment depends on the stage, tumor characteristics, whether the cancer has spread, response to treatment, and overall health. Some localized rectal cancers can be treated with curative intent.
Not necessarily. Treatment depends on the stage and characteristics of the cancer. Some very early tumors may be treated with local excision, while other cancers require more extensive surgery. Some patients may also receive systemic or radiation-based treatment as part of their overall plan.
Selected patients may undergo non-operative management after an excellent response to preoperative treatment, with careful surveillance. This approach is appropriate only for selected patients and requires close specialist follow-up.
In selected patients, sphincter-preserving surgery may be possible. It depends on the tumor's location, extent, response to treatment, and whether adequate cancer-free margins can be achieved.
Not every patient requires a colostomy. Some patients can have the bowel reconnected after tumor removal. A temporary or permanent stoma may be necessary in selected cases depending on the tumor location, operation, and individual circumstances.
Depending on your case, evaluation may include colonoscopy and biopsy, MRI of the pelvis, CT imaging, blood tests, CEA testing, and molecular or pathological investigations.
Yes. Rectal cancer can spread to distant organs, including the liver and lungs. Selected patients with limited metastatic disease may be evaluated for surgery or other local treatments as part of a multidisciplinary approach.
