Radiation Oncology

Radiation oncology is the medical unit that treats cancer with radiotherapy — precisely targeted radiation that destroys cancer cells while sparing as much healthy tissue as possible. At Acıbadem International, radiotherapy is never delivered in isolation: every patient’s plan is agreed within a multidisciplinary tumor board alongside medical oncology, surgery and imaging, so that radiation, drug therapy and surgery work together as one strategy against the cancer. For people travelling from abroad for cancer treatment, that combination of modern radiotherapy technology and genuinely coordinated care is exactly what gives the best chance of a good outcome.

This page explains what the radiation oncology unit covers, the cancers it treats, how treatment is planned, the techniques available, and how international patients are supported through what is often a demanding journey.

What the radiation oncology unit covers

Radiation oncology uses carefully planned, precisely delivered radiation to treat cancer, and the unit is organized so that the right technique is applied to each situation. Its main areas of work include:

• External beam radiotherapy — precisely targeted radiation delivered from outside the body.
• Advanced precision techniques — including intensity-modulated and image-guided radiotherapy.
• Stereotactic radiotherapy and radiosurgery — highly focused treatment for selected tumors.
• Radiotherapy as part of combined treatment — alongside surgery and drug therapy.
• Palliative radiotherapy — to relieve symptoms and improve comfort where appropriate.

Radiation is one of the three main pillars of cancer treatment, alongside surgery and drug therapy. Because the best results usually come from combining these in the right way, radiotherapy is planned within a multidisciplinary team rather than chosen in isolation.

Cancers we treat

The unit treats a wide range of cancers with radiotherapy, either as a primary treatment or as part of a combined plan. Common situations include:

• Breast cancer — often after surgery to reduce the risk of recurrence.
• Prostate cancer — where radiotherapy can be a primary treatment.
• Lung and other thoracic cancers.
• Head and neck cancers.
• Brain tumors — including with stereotactic techniques, alongside neurosurgery.
• Gastrointestinal, gynecological and many other cancers.

Many patients arrive with a cancer diagnosis from home and an urgent need for a clear, coordinated plan. The unit’s role is to determine whether and how radiotherapy fits into that plan, and to deliver it precisely and safely as part of the whole strategy.

How treatment is planned

Precision in radiotherapy begins long before the first treatment, with careful planning that is one of the most important parts of the process. Planning typically involves:

• Detailed imaging — CT, and often MRI or PET, to define exactly where the tumor is.
• Target definition — mapping precisely what should be treated and what should be protected.
• Dose planning — calculating how to deliver an effective dose to the tumor while sparing healthy tissue.
• Quality checks — verifying the plan before treatment begins.

This planning draws on the hospital group’s medical technologies, radiology and, where relevant, nuclear medicine, and the overall strategy is agreed by the tumor board. For international patients, the planning process and tumor-board review can begin from reports and imaging shared remotely, so that a clear plan is in place before travel.

Techniques and treatments

The unit uses modern radiotherapy techniques, choosing the approach that delivers the most effective, precise and safe treatment for each cancer.

External beam radiotherapy

The most common form of radiotherapy delivers precisely targeted radiation from outside the body over a planned course of sessions. Modern delivery is highly accurate, shaping the radiation to the tumor and limiting the dose to surrounding tissue.

Intensity-modulated and image-guided radiotherapy

Advanced techniques allow the radiation dose to be shaped very precisely around the tumor, and imaging during treatment helps ensure accuracy. Together, these reduce the dose to healthy tissue, which can improve safety and reduce side effects.

Stereotactic radiotherapy and radiosurgery

For selected tumors, highly focused techniques deliver a very precise, concentrated dose, sometimes in a small number of sessions. These approaches are used where they are appropriate, including for some brain tumors in cooperation with neurosurgery.

Radiotherapy within combined treatment

Radiotherapy is frequently combined with surgery and drug therapy — for example, after surgery to reduce recurrence, or alongside chemotherapy. The sequence and combination are decided by the tumor board so that each element supports the others. Specific treatments can be explored in the treatments library.

The multidisciplinary tumor board

The single most important feature of modern cancer care is the multidisciplinary tumor board — radiation oncologists, medical oncologists, surgeons, radiologists and pathologists reviewing each case together and agreeing the best plan. This matters because most cancers are best treated with a combination of approaches in the right sequence, and no single specialty should decide that alone. At Acıbadem International, radiotherapy is always planned within this team, so the treatment a patient receives reflects combined expert judgment. For international patients, this coordinated approach — and the reassurance of a clear, considered plan — is precisely what cancer care should provide.

Technology and precision

Radiation oncology is among the most technology-driven fields in medicine, because effective, safe radiotherapy depends on extraordinary precision. The unit uses detailed imaging to define the target, advanced planning to shape the dose, and image-guided delivery to treat accurately, all aimed at destroying cancer while protecting healthy tissue. But technology serves a coordinated strategy: the decision of whether, when and how to use radiotherapy is made by the tumor board, so precision in delivery is matched by sound judgment in planning. This combination is what underpins good radiotherapy outcomes.

Managing side effects and supportive care

Radiotherapy is generally well tolerated, but it can cause side effects depending on the area treated, and the unit pays careful attention to managing these. Patients are informed in advance about what to expect, monitored during treatment, and supported with measures to ease side effects and maintain wellbeing. Supportive care — including attention to nutrition and, where helpful, other specialties — is part of the approach, because treating the cancer well also means caring for the patient throughout. The unit is honest and clear about side effects so that patients are prepared rather than anxious.

Your multidisciplinary team

Your care may involve a radiation oncologist, medical physicists, radiation therapists, a medical oncologist, surgeons and specialist nurses, all working within the tumor board. The physicians who lead this unit are listed on the doctors page, and treatment is delivered across Acıbadem’s accredited hospitals, which maintain international quality and safety standards.

The international patient journey

Radiotherapy follows a planned course, so travel needs careful coordination. The unit is organized to make this clear and supportive for international patients.

1. Remote review of your case

You begin by sharing your diagnosis, pathology and imaging. The team reviews them, often within the tumor board, and provides an opinion on whether and how radiotherapy fits into your plan. A second opinion is available — entirely remotely, before you commit to travel.

2. A clear plan and timeline

If treatment in Turkey makes sense, you receive a plan describing the recommended approach, how the course would be delivered, how long you would need to stay, and what to expect. Because radiotherapy is delivered over a planned course, the timeline is set out clearly.

3. Coordinated treatment

A dedicated coordinator arranges your planning scans, treatment course, accommodation, interpreting and travel logistics. Your plan is confirmed and quality-checked before treatment begins.

4. Follow-up

You receive clear documentation and a follow-up plan to continue at home, and the team remains reachable for questions. To begin, request an online consultation.

Why patients choose Acıbadem for radiotherapy

Acıbadem International offers experienced radiation oncologists, modern radiotherapy technology, a true multidisciplinary tumor board, and well-coordinated international patient support — all within accredited hospitals. For patients travelling for cancer treatment, the combination of precise technology and genuinely coordinated care is what sets the experience apart: the radiotherapy a patient receives is part of one strategy agreed by the whole cancer team, not an isolated treatment. The unit aims to treat cancer as effectively and safely as possible, with the depth of a leading medical system behind it.

What to expect and practical notes

A course of radiotherapy is usually delivered over a planned series of sessions, and your coordinator plans your stay around the full course. The unit is honest about what treatment involves, including possible side effects, so you are prepared. Importantly, radiotherapy is recommended only where it genuinely benefits the patient as part of the overall plan; the decision is made by the tumor board, not in isolation. Throughout, the aim is to deliver effective treatment precisely while caring for your wellbeing, with clear information at every step.

Coordinated care across the cancer journey

Cancer treatment almost always involves more than one approach, and treatment within a large hospital group means the right experts work together. Radiotherapy is planned alongside medical oncology and surgery; imaging is supported by radiology and nuclear medicine; and brain tumors are treated in cooperation with neurosurgery. Supportive care, nutrition and rehabilitation are available within the same group. This joined-up approach means a patient’s cancer journey is managed as a connected whole, which matters enormously in treatment as complex and high-stakes as cancer care.

Understanding how radiotherapy works

Radiotherapy works by delivering carefully measured doses of radiation to a tumor, damaging the cancer cells so that they cannot continue to grow and divide, while healthy cells in the surrounding area are given the best possible chance to recover. The treatment is invisible and painless at the time it is given, much like having an imaging scan, and it is usually delivered in a series of sessions spread over a planned period. This fractionation — dividing the total dose into smaller daily treatments — is deliberate, allowing healthy tissue to recover between sessions while the cumulative effect on the tumor builds. Understanding this helps patients see why a course of radiotherapy takes the form it does, and why attending each planned session matters. The unit explains the approach for each patient clearly, so that what can feel like an abstract or daunting treatment becomes something understandable and manageable. For many cancers, radiotherapy is a powerful and well-established treatment, used either on its own or as part of a combined strategy.

Why precision matters so much

The central challenge of radiotherapy is to deliver enough radiation to control the cancer while protecting the healthy tissue nearby, and this is why precision is everything. Modern planning begins with detailed imaging that defines exactly where the tumor is and what surrounds it, allowing the team to shape the radiation to the target and limit the dose elsewhere. During treatment, imaging helps confirm that the radiation is delivered accurately each time. The more precisely radiation can be focused, the more effectively the tumor can be treated and the lower the risk to healthy tissue — which is why advanced techniques such as intensity-modulated and image-guided radiotherapy represent such an important advance. The unit’s investment in precision is not technology for its own sake; it is directly in the service of treating cancer effectively while caring for the patient’s wider wellbeing, and it is one of the reasons modern radiotherapy is so much more refined than in the past.

What a course of treatment is like

For most patients, a course of external beam radiotherapy involves attending for short, regular sessions over a planned period, with each individual session typically taking only a short time. Before the course begins, a planning session and scans are carried out to design the treatment precisely, and the plan is checked carefully for accuracy. During the course, the patient is monitored, and any side effects are managed as they arise. Because the treatment is delivered over time, the unit plans an international patient’s stay around the full course and explains the timeline clearly in advance. While radiotherapy is demanding in its own way, many patients are able to maintain much of their daily routine during treatment, and the team supports them throughout. Knowing what to expect — the planning, the sessions, the monitoring and the follow-up — helps patients approach the course with confidence rather than uncertainty.

Radiotherapy in common cancers

Radiotherapy plays an important role in many of the most common cancers. In breast cancer, it is frequently used after surgery to reduce the risk of the cancer returning, as part of a carefully sequenced plan. In prostate cancer, radiotherapy can be a primary treatment, offering an effective option that does not involve surgery. It also has key roles in lung, head and neck, gynecological, gastrointestinal and many other cancers, sometimes as the main treatment and sometimes combined with surgery or drug therapy. In each case, the decision about whether and how to use radiotherapy is made within the multidisciplinary tumor board, so that it forms part of the best overall strategy for that particular cancer and that particular patient. This individualized, team-based planning is what ensures radiotherapy is used to greatest effect.
