Advanced Radiation Oncology Treatments Offered

Radixact X9 Tomotherapy

The Radixact X9 delivers radiation in a continuous spiral, rotating fully around the patient while the treatment couch advances through the ring. This helical motion allows beams to approach the tumor from every angle, shaping the dose tightly around complex or irregularly distributed tumors while limiting exposure to surrounding tissue.

An integrated CT scanner captures images before each session, letting clinicians verify positioning and adapt to any changes in anatomy or tumor size. A real-time motion tracking system adjusts delivery mid-treatment if the target shifts. It is particularly suited for extended-field cases such as recurrent head and neck cancers.

Versa HD

The Versa HD is a high-performance linear accelerator designed to deliver precise, high-dose radiation across a broad range of cancer types and treatment approaches. Its flattening-filter-free beam mode increases dose rate substantially, reducing overall treatment time and helping maintain accuracy during techniques that require breath-holding.

The system supports stereotactic radiosurgery, SBRT, IMRT, and VMAT, making it adaptable to both complex intracranial targets and larger tumors in the body. Built-in surface-guided radiation therapy and cone-beam CT imaging allow clinicians to verify the patient's position before and during treatment, accounting for movement without interrupting the session unnecessarily

Advanced Radiation Therapy Infrastructure

State-of-the-art radiation machines: The flagship TomoTherapy platform delivers radiation in a helical pattern, enabling 360-degree tumor targeting. The hospital also has the Versa HD platform, which enables precise targeting and radiation delivery for a wide range of cancers.

Real-time imaging and adaptive planning: Daily image-guided radiation therapy (IGRT) verifies tumor position before every session, while Ethos Adaptive Radiation Therapy dynamically adjusts treatment plans based on patient response.

High-precision dose delivery systems: Advanced platforms enable highly conformal dose delivery, minimizing exposure to surrounding healthy tissues and improving treatment accuracy.

Cancers Treated with Radiation Therapy

At HCG, radiation therapy is recommended for a wide range of cancers.

  • Brain and spine tumors: Advanced techniques like SRS for small brain metastases and SBRT for spine lesions enable precise, high-dose treatment.
  • Head and neck cancers: Concurrent chemoradiation is commonly used for locally advanced stages (Stage III-IVA) to improve outcomes.
  • Breast and Prostate cancers: Includes whole breast radiation after lumpectomy, post-mastectomy therapy for node-positive cases, and prostate treatments using IMRT, SBRT, or brachytherapy based on risk level.
  • Lung and gastrointestinal cancers: SBRT for early-stage inoperable lung cancer, chemoradiation for advanced lung cases, and targeted therapy for esophageal and rectal cancers.

Why Choose HCG as a Radiation Oncology Hospital in Kolkata?

Every radiation plan at HCG Kolkata gets reviewed by the entire expert team. Radiation oncologists, medical oncologists, surgeons, radiologists, and pathologists gather together before treatment starts. That review determines the dose, schedule, and technique. It isn't a formality. It's how the course gets matched to the actual disease.

For patients evaluating a radiation oncology hospital in Kolkata, here's what the center offers:

  • Experienced radiation oncologists trained in external beam, image-guided, stereotactic, and brachytherapy techniques.
  • Advanced radiation technology, including modern systems that enable precise tumor targeting and adaptive treatment planning.
  • Precision-targeted cancer treatment with daily imaging and dosimetry checks.
  • Patient safety through protocol-driven planning and real-time position verification.
  • NABH-accredited cancer hospital, ensuring adherence to established quality and safety standards.

Frequently Asked Questions

What is radiation oncology, and how does it help in cancer treatment?

+

Radiation oncology uses targeted high-energy radiation to kill cancer cells or stop them from multiplying. It's used as primary treatment, before or after surgery, or with chemotherapy per NCCN guidelines. Modern platforms shape the beam around the tumor so healthy tissue gets a lower dose. At HCG Kolkata, plans are built inside a tumor board.

When should a patient consult a radiation oncology hospital in Kolkata?

+

Anyone newly diagnosed with cancer should see a radiation oncologist as part of treatment planning. Early input means radiation is properly considered, not added later. It's also useful for recurrence, when chemotherapy alone isn't controlling the disease, when pain or bleeding needs palliation, or for a second opinion before starting.

Is Radixact TomoTherapy available in Kolkata for cancer treatment, and what makes it different from conventional radiotherapy?

+

Yes. HCG Kolkata has Radixact installed on-site. It delivers radiation in a helical pattern while using daily imaging to verify tumor position. The short answer to the difference is better targeting for complex tumor shapes and more room for spare critical organs. That matters for head and neck, prostate, and some thoracic cases.

My oncologist has recommended radiation therapy; how many sessions will I need, and what does each session actually feel like?

+

It depends on the cancer, dose, and technique. Standard external beam runs five days a week for 3 to 7 weeks. Stereotactic courses compress a high dose into one to five sessions. Each session is painless and takes 15 to 30 minutes, most of which is spent positioning you. Patients go home right after.

I have been told I need concurrent chemoradiation; is it safe to receive both at the same time?

+

Concurrent chemoradiation is a recognized approach for head and neck, cervical, esophageal, and locally advanced lung cancers. Giving both at once can work better than sequencing them. At HCG Kolkata, the teams track response and side effects closely and adjust supportive care so the regimen stays on schedule.

What side effects should I expect during radiation therapy, and how are they managed so I can still function day to day?

+

It depends on where the radiation is aimed. Fatigue and skin changes in the treated area are common, peaking in weeks 3 to 5. Head and neck radiation can cause dry mouth and swallowing trouble; pelvic radiation can affect the bowel or bladder. Most build gradually and settle 2 to 4 weeks after the last session with supportive care.

Can I get a second opinion on my radiation plan before starting treatment in Kolkata?

+

Yes. Patients with a plan elsewhere can request an independent review from HCG Kolkata's radiation oncology team. The second opinion may confirm the plan, suggest adjustments, or recommend a different approach. Asking doesn't commit you to switching hospitals. Bring scans, pathology, and treatment records so the review is thorough.

Is radiation therapy safe and precise at HCG Cancer Hospital?

+

Yes. Every plan at HCG Kolkata is built around ICRU-compliant target contouring, physicist-led dosimetry per AAPM standards, and daily image-guided verification before each session. Tumor board review approves the plan before treatment starts. Side effects still happen, but dose to healthy tissue is kept as low as clinically feasible.
