Advanced Radiation Therapy in Noida, Delhi, India

Precision Cancer Treatment with Cutting-Edge Technology

Radiation therapy (Radiotherapy) is a cornerstone of modern cancer care, using high-energy X-ray beams to destroy the DNA of cancer cells and stop them from multiplying. At Metro Hospitals, our Radiation Oncology department utilizes the most advanced linear accelerators and specialized techniques to target tumors with sub-millimeter precision.

Our goal is to maximize the radiation dose to the tumor while strictly protecting the surrounding healthy organs, ensuring better outcomes and faster recovery.

Types of Radiation Therapy at Metro Hospitals

We offer a full spectrum of radiotherapy options, categorized into two main delivery methods:

1. External Beam Radiation Therapy (EBRT)

The most common form of treatment, where radiation is delivered from a machine outside the body. We specialize in:

• IMRT (Intensity-Modulated Radiation Therapy): Shapes the radiation beams to match the 3D volume of the tumor.
• IGRT (Image-Guided Radiation Therapy): Uses real-time imaging (CT/X-ray) before every session to ensure perfect alignment.
• SBRT (Stereotactic Body Radiation Therapy): Delivers ultra-high doses of radiation in just a few sessions for small, well-defined tumors.
• Respiratory Gating (DIBH): A specialized technique for Left-Sided Breast Cancer and Lung Cancer, where radiation is only delivered when the patient holds their breath to protect the heart and lungs.

2. Internal Radiation (Brachytherapy)

Radioactive sources are precisely placed within or near the tumor to deliver targeted and effective treatment.

• Temporary Brachytherapy: Used commonly for Cervical and Uterine cancers.
• IORT (Intraoperative Radiation Therapy): A concentrated dose delivered directly to the tumor bed during surgery.

Goals of Radiation Treatment

Depending on the stage of cancer, our specialists use radiation for:

• Curative Intent: To eradicate the cancer completely.
• Neoadjuvant Therapy: To shrink a tumor before surgery.
• Adjuvant Therapy: To kill any microscopic cells remaining after surgery.
• Palliative Care: To relieve pain and improve the quality of life in advanced stages.

What to Expect: The Procedure Pathway

Step 1: Planning (Simulation) A customized mold or mask is created to keep your body still. You will undergo a Planning CT Scan so our physicists can map the exact target area.

Step 2: Quality Assurance (QA) Before your first session, our medical physicists run a “dry run” on the machine to ensure the dose is 100% accurate.

Step 3: Treatment Sessions Actual radiation delivery takes only 2–5 minutes. The total session (including positioning and imaging) lasts about 15–20 minutes. Most treatments are daily, 5 days a week, for several weeks.

Step 4: Monitoring You will have weekly reviews with your Radiation Oncologist to manage side effects and monitor progress.

Expert-Verified FAQs

1. Is radiation therapy painful?

No, the treatment itself is completely painless—much like getting a standard X-ray. You do not feel the beams entering your body. Any discomfort, such as skin irritation or fatigue, typically develops gradually over several weeks and is manageable with supportive care.

2. Am I “radioactive” after the treatment?

For External Beam Radiation, no. Once the machine is turned off, there is no radiation in your body. It is perfectly safe to be around family, children, and pregnant women immediately after your session.

3. What are the common side effects?

Side effects are usually localized to the area being treated. For example, head and neck radiation may cause a dry mouth, while pelvic radiation might cause loose motions. Fatigue is the most common general side effect. Most of these are temporary and disappear after treatment ends.

4. How safe is Radiation Therapy at Metro Hospital?

We follow international safety protocols. Every treatment plan is checked by a Medical Physicist and verified by Image-Guided technology (IGRT) before the beam is turned on. This ensures that the risk to healthy tissue is kept at an absolute minimum.

5. Which cancers are most commonly treated with radiation?

Radiation is highly effective for Breast, Prostate, Lung, Brain, Head & Neck, Cervical, and Rectal cancers. Our team at Metro Hospitals Noida and Delhi uses it as a primary treatment or in combination with chemotherapy.
