In a landmark achievement in advanced cancer care, doctors at All India Institute of Medical Sciences (AIIMS), New Delhi have successfully removed a nearly 20-kilogram Stage IV colon cancer tumour from a 43-year-old woman, offering her a new lease of life and underscoring India’s growing expertise in complex oncological surgeries.


The patient, Ms Munmun, a resident of Durgapur in West Bengal, was suffering from advanced metastatic colon cancer that had spread to multiple organs, including the liver, uterus, ovary and peritoneum. She reported to AIIMS in July 2024 with severe abdominal distension, after which an extensive evaluation revealed the life-threatening nature of the disease.


Following diagnosis, the patient underwent systemic chemotherapy, receiving six cycles of FOLFOX with bevacizumab, followed by one cycle of FOLFIRI, which resulted in a partial metabolic response on PET-CT.


Complex Two-Stage Surgery Led by Prof. M.D. Ray
On January 12, 2026, a highly specialised multidisciplinary team led by Prof. M.D. Ray, Department of Surgical Oncology, AIIMS Delhi, performed an extensive cytoreductive surgery, achieving complete tumour removal. Nearly 19.9 kilograms of tumour mass, along with affected organs, were successfully excised.


To complete the comprehensive cancer treatment, a second-stage procedure involving HIPEC (Hyperthermic Intraperitoneal Chemotherapy) was carried out on January 15, 2026, significantly reducing the risk of residual microscopic disease.


Following surgery, the patient was shifted from the Intensive Care Unit to the general ward and is recovering satisfactorily. She will continue on maintenance therapy and targeted treatment as part of her post-operative care plan.


Lifestyle Factors Behind Rising Colon Cancer Cases
Speaking on the occasion, Prof. M.D. Ray drew attention to the alarming rise in colon cancer cases, linking it strongly to lifestyle choices.


“Colon cancer is increasingly associated with unhealthy habits such as excessive consumption of red meat and fast food, chronic constipation, irregular bowel movements and a sedentary lifestyle. Continuous physical irritation of the colon significantly raises cancer risk,” he said.


Prof. Ray also highlighted the often-neglected role of mental health in cancer treatment outcomes.
“Patients with strong mental resilience respond better to treatment. I strongly encourage yoga, meditation and regular physical activity, as they reduce stress, strengthen immunity and support overall recovery,” he added.


AIIMS Delhi’s Excellence in Advanced Cancer Care
The successful surgery once again showcases AIIMS Delhi’s leadership in handling complex, late-stage cancers, combining cutting-edge surgical expertise, medical oncology, and holistic supportive care under one roof.


Doctors at the institute emphasised that while advanced medical interventions can save lives, prevention remains the most effective weapon against cancer. Reducing red meat intake, adopting a balanced diet, maintaining physical activity, managing stress through yoga and meditation, and seeking timely medical advice for digestive symptoms can significantly lower the risk of colorectal cancer.


This remarkable case stands not only as a medical milestone but also as a national public health message, reinforcing the importance of early diagnosis, lifestyle awareness and holistic cancer care in India’s fight against cancer.
