15 Frequently Asked Questions : Radiotherapy and Modern Cancer Treatments in India for Zambian Patients

Q1 · What Is Radiotherapy?

Radiotherapy is a cancer treatment that uses ionizing radiation to damage cancer cells and prevent them from growing and dividing.

Radiation may be delivered:

External Beam Radiotherapy

Radiation is delivered from a machine outside the body and directed toward the tumour.

Brachytherapy

A radioactive source is placed inside or very close to the tumour so that radiation can be delivered directly to the treatment area. The source may be positioned through intracavitary, interstitial or surface techniques depending on the cancer.

Particle Therapy

Particle therapy, including proton therapy, uses high-energy particles to deliver radiation to selected tumours. It may be considered when reducing radiation exposure to nearby normal tissues is particularly important.

Radiotherapy may be used alone or together with surgery, chemotherapy, targeted therapy or immunotherapy.

Q2 · What Is the Cost of Radiotherapy and Modern Cancer Treatment in Zambia Compared with India?

The cost varies according to the radiation technique, number of treatment sessions, cancer type, treatment planning, hospital and whether chemotherapy or other treatment is given simultaneously.

For planning purposes, the comparison below uses:

• US$1 ≈ ZMW 19.5
• US$1 ≈ INR 96

Indicative Cost Comparison

Current Indian 2026 pricing information gives approximately INR 60,000–150,000 for 3D- CRT, INR 120,000–190,000 for IMRT and INR 180,000–250,000 for IGRT at one cancer centre, while corporate-hospital estimates can be higher.

Another Indian cancer centre reports approximate ranges of INR 6,000–12,000 per session for 3D-CRT, INR 8,000–18,000 for IMRT/IGRT, INR 10,000–20,000 for VMAT, INR 20,000–40,000+ for SBRT and INR 20,000–50,000+ for SRS, although the total course cost depends on the number of sessions.

For proton therapy, current published Indian estimates from Apollo Proton Cancer Centre are approximately INR 25–50 lakh, depending on cancer type, stage, number of sessions and treatment requirements.

Important: The Zambia figures are indicative private-healthcare planning ranges rather than fixed quotations from a particular Zambian hospital. The India figures are also indicative. The final quotation should be obtained after review of the patient's diagnosis and treatment plan.

Q3 · Which Major Indian Cities Can Zambian Patients Consider for Radiotherapy and Modern Cancer Treatment?

The city should be selected according to the patient's cancer type, required radiation technology, availability of the necessary equipment, oncology team and expected duration of treatment.

Q4 · Which Hospitals in India Can Zambian Patients Consider?

Important: This is a broad list for initial consideration. Not every hospital listed necessarily provides every advanced radiotherapy technology or proton therapy. The exact technology should be confirmed against the patient's treatment requirement.

Q5 · What Types of Modern Radiotherapy Are Available in India?

1. 3D-Conformal Radiotherapy — 3D-CRT

3D-CRT uses three-dimensional imaging to shape radiation fields around the tumour.

It can be used for many common cancers and remains an important external-beam technique.

2. Intensity-Modulated Radiotherapy — IMRT

IMRT allows the intensity of radiation beams to be varied across the treatment field.

It can help shape the radiation dose around complex tumour volumes and reduce radiation exposure to selected surrounding tissues.

3. Image-Guided Radiotherapy — IGRT

IGRT uses imaging during treatment to improve positioning and account for changes in tumour or patient anatomy. It may be particularly useful when tumours are near sensitive structures or when movement can affect treatment accuracy.

4. Volumetric Modulated Arc Therapy — VMAT

VMAT delivers radiation while the treatment machine rotates around the patient, allowing dose intensity and beam delivery to be modulated.

5. Stereotactic Body Radiotherapy — SBRT

SBRT delivers highly focused radiation in a small number of treatment sessions and may be used for selected tumours.

6. Stereotactic Radiosurgery — SRS

SRS delivers highly focused radiation to selected targets, particularly in certain brain and other intracranial conditions.

7. Brachytherapy

A radioactive source is placed inside or close to the tumour.

It is commonly considered for selected cancers including cervical, prostate, breast and other appropriately located tumours.

8. Proton Therapy

Proton therapy uses proton beams rather than conventional photon radiation. It may be considered for selected tumours where reducing radiation exposure to nearby normal tissues is particularly important.

Q6 · What Is the Difference Between IMRT, IGRT, VMAT, SBRT and Proton Therapy?

IMRT

Focuses on modulating radiation intensity to create a more conformal dose distribution.

IGRT

Focuses on imaging and treatment-position verification before or during radiation delivery.

VMAT

Delivers modulated radiation while the machine rotates around the patient.

SBRT

Uses highly precise radiation delivered in a relatively small number of sessions for appropriately selected tumours.

Proton Therapy

Uses proton particles and has different physical dose-distribution characteristics from conventional photon therapy.

These technologies are not interchangeable. The most sophisticated or expensive technology is not automatically appropriate for every cancer.

The radiation oncologist selects the technique according to tumour location, size, stage, nearby organs, previous radiation exposure and treatment objective. India's AIIMS radiation-oncology service lists 3D-CRT, IMRT, VMAT, IGRT, SRS/SBRT, brachytherapy and Gamma Knife among its modern radiation techniques.

Q7 · Which Cancers May Require Modern Radiotherapy?

Radiotherapy may be used in many cancer types, including:

• Breast cancer
• Prostate cancer
• Lung cancer
• Head and neck cancer
• Brain tumours
• Cervical cancer
• Uterine cancer
• Rectal cancer
• Oesophageal cancer
• Anal cancer
• Liver cancer
• Bone metastases
• Spinal metastases
• Selected pancreatic cancers
• Selected paediatric cancers
• Lymphomas
• Soft-tissue tumours

Radiotherapy may be used:

• Before surgery
• After surgery
• Together with chemotherapy
• As the primary treatment
• For local control
• For symptom relief

The appropriate technique depends on the specific cancer and treatment objective.

Q8 · What Medical Reports Should a Zambian Patient Send Before Travelling to India?

The patient should ideally provide:

• Oncologist report
• Radiation-oncology consultation, if available
• Biopsy report
• Histopathology report
• Immunohistochemistry
• Molecular/biomarker reports
• PET-CT
• CT scans and images
• MRI scans and images
• Previous operation report
• Previous chemotherapy records
• Previous radiotherapy records
• Previous radiation treatment plan, if applicable
• Treatment-response scans
• Blood-test reports
• Current medication list
• Previous discharge summaries

For patients who have already received radiation, the previous radiation dose, treatment fields, technique and treatment summary are particularly important because previous radiation can influence future treatment options.

Q9 · What Is the Typical Radiotherapy Treatment Process in India?

Step 1 – Radiation Oncology Consultation

The radiation oncologist reviews the diagnosis, pathology, scans and previous treatment.

Step 2 – Treatment Planning

The team determines:

• Whether radiotherapy is required
• Treatment intent
• Target area
• Dose
• Number of sessions
• Appropriate technology

Step 3 – CT Simulation

A CT simulation is generally performed to establish the patient's treatment position and create the radiation-treatment plan. India's AERB describes simulation as an important step for positioning, immobilization, field size and treatment planning.

Step 4 – Treatment Planning

Radiation oncologists, medical physicists and dosimetrists develop and verify the treatment plan.

Step 5 – Radiation Delivery

Treatment may be delivered using:

• 3D-CRT
• IMRT
• IGRT
• VMAT
• SBRT
• SRS
• Brachytherapy
• Proton therapy

Step 6 – On-Treatment Monitoring

The patient is reviewed periodically for side effects, nutrition, medication and treatment response.

Step 7 – Treatment Completion

A treatment summary is prepared and follow-up is scheduled.

Q10 · Are There Alternatives to Radiotherapy?

Yes. Radiotherapy is only one component of cancer treatment.

Depending on the cancer, alternatives or complementary treatments may include:

• Surgery
• Chemotherapy
• Targeted therapy
• Immunotherapy
• Hormone therapy
• Ablation
• Embolization
• Active surveillance in selected cancers
• Palliative treatment

In many cancers, radiotherapy is combined with another treatment rather than used alone.

The choice should be based on pathology, stage and the patient's overall treatment plan.

Q11 · What Should a Zambian Patient Ask for in the Final Treatment Quotation?

Before travelling to India, the patient should request a written treatment estimate specifying:

Radiotherapy

• Radiation technique
• Machine/platform
• CT simulation
• Treatment planning
• Number of sessions
• Radiation dose
• Image guidance
• Immobilization devices
• Doctor fees
• Medical physicist/dosimetry charges
• Treatment delivery
• Follow-up

Brachytherapy

• Type of brachytherapy
• Number of applications
• Applicator/device charges
• Anaesthesia, if required
• Imaging
• Hospital stay

Proton Therapy

• Proton treatment planning
• Number of fractions
• Imaging
• Treatment delivery
• Associated consultations
• Accommodation/hospital services where applicable

Combined Treatment

If chemotherapy, targeted therapy or immunotherapy is being given together, ask for:

• Drug name
• Dose
• Number of cycles
• Cost per cycle
• Blood tests
• Supportive medicines
• Administration charges

Current Indian radiotherapy estimates show substantial differences between 3D-CRT, IMRT, IGRT, VMAT and stereotactic treatments, making an itemized quotation important.

Q12 · How Long Should a Zambian Patient Stay in India?

The required stay depends on the radiation technique and number of sessions.

Many conventional radiotherapy courses involve multiple daily sessions. A current Indian radiation-oncology source states that treatment commonly involves approximately 15–35 sessions, depending on cancer type and treatment plan.

Proton therapy can also involve several weeks of treatment depending on the cancer and prescribed course.

The final stay should be confirmed by the treating radiation oncologist.

Q13 · What Is Recovery Like After Radiotherapy and Modern Cancer Treatment?

Recovery varies according to the treatment area, dose, number of sessions and whether other treatments are given simultaneously.

Common Possible Effects

Some patients may experience:

• Fatigue
• Skin changes
• Reduced appetite
• Local irritation
• Swelling
• Treatment-area discomfort

Side effects depend strongly on the body region being treated.

Head and Neck Radiotherapy

Possible issues may include:

• Mouth/throat irritation
• Difficulty swallowing
• Taste changes
• Dry mouth
• Nutrition difficulties

Chest Radiotherapy

Possible effects may include:

• Fatigue
• Cough or irritation
• Skin changes

Abdominal/Pelvic Radiotherapy

Possible effects may include:

• Bowel changes
• Urinary symptoms
• Fatigue
• Skin irritation

Brachytherapy

Recovery depends on the treated area and the technique used.

Proton Therapy

Side effects can still occur because proton therapy remains a form of radiation treatment, although its physical dose distribution may help reduce radiation exposure to selected nearby tissues in appropriate cases.

Patients should follow the radiation team's instructions regarding nutrition, skin care, activity and follow-up.

Q14 · What Follow-up Care Is Required After Returning to Zambia?

Before leaving India, the patient should collect:
