Introduction

When people hear the word cancer, surgery may not be the first treatment that comes to mind. Yet, cancer surgeons (oncosurgeons) play a pivotal role in diagnosing, treating, and guiding patients throughout their cancer journey.

For decades, oncosurgeons have stood at the forefront of the fight against cancer. Thanks to their relentless efforts, cancer is no longer viewed as a “death sentence” but rather a chronic condition that can be managed effectively with modern treatment.

“At Moolchand Hospital, our superb physicians deliver outcomes that matter—combining cutting-edge technology, integrity, and compassionate care,” says Dr. Bimlesh Thakur, Consultant – Surgical Oncology.

The Role of an Oncosurgeon

An oncosurgeon is a specialist who performs surgery to diagnose, treat, and sometimes prevent cancer. Their responsibilities include:

• Diagnosis: Performing biopsies and tissue sampling to confirm cancer.
• Treatment Planning: Removing tumors with precision while preserving healthy organs and surrounding tissues.
• Prevention: Performing surgeries for patients at high genetic or familial risk (e.g., BRCA1/BRCA2 mutation carriers).
• Comprehensive Cancer Care: Collaborating with medical oncologists, radiation oncologists, radiologists, and physicians for a multidisciplinary approach.

“Surgical oncology is not just about removing a tumor—it’s about restoring life, function, and hope,” says Dr. Thakur.

Why Surgical Oncology Matters

Surgery remains one of the most effective and often curative cancer treatments.

• Early and quality surgery can completely remove certain cancers.
• Improves quality of life by reducing pain or relieving blockages.
• Guides further treatment by providing insight for tailored chemotherapy or radiation therapy.

In cases such as breast cancer, head and neck cancer, and gynaecologic cancers, early surgery is often the key to a complete cure.
