When a patient is diagnosed with a tumour in the brain, the word “surgery” can be frightening. Many people immediately think about an operation, a surgical incision and a long recovery period.
However, Stereotactic Radiosurgery (SRS) is different.
Despite the word surgery in its name, SRS is a highly focused form of radiation treatment and does not involve a conventional surgical incision. It uses carefully planned radiation beams to deliver treatment to a precisely defined target.
For patients searching for SRS Therapy for Cancer Treatment in Dwarka, understanding how the treatment works—and, just as importantly, when it should be used—is essential.
SRS is not a treatment that is suitable for every cancer patient. It is generally considered for carefully selected lesions, particularly certain tumours or metastases involving the brain and other areas where highly precise radiation can be useful.
Dr Mohit Kadian, Consultant in Radiation Oncology, is part of the Radiation Oncology team at Venkateshwar Hospital in Dwarka. The hospital lists frameless Stereotactic Radiosurgery (SRS) among its specialised radiation services, along with SBRT, VMAT, IGRT/IMRT and PET/MRI fusion-based radiation planning.
SRS stands for Stereotactic Radiosurgery.
It is a precision radiation treatment in which multiple radiation beams are carefully directed toward a specific target. The beams are planned so that the prescribed radiation dose is concentrated at the treatment site.
Unlike conventional brain surgery, SRS does not require the surgeon to make an incision.
The objective is to treat the targeted lesion while limiting unnecessary radiation exposure to surrounding healthy tissues as much as possible.
SRS is most commonly associated with selected conditions involving the brain, although stereotactic radiation approaches can also be used in other areas of the body.
The term “radiosurgery” can therefore be slightly misleading for someone hearing it for the first time.
There is no surgical cutting involved.
The SRS process starts well before the patient enters the treatment room.
The radiation oncologist first needs to understand exactly what is being treated.
This usually involves reviewing:
Once the target has been identified, the treatment team creates a highly detailed radiation plan.
The patient's position is carefully reproduced during treatment, and image guidance can be used to verify positioning.
The radiation is then delivered according to the approved treatment plan.
Venkateshwar Hospital lists a Versa HD linear accelerator, a hexapod table for precise positioning and MRI-based radiotherapy simulation technology as part of its radiation oncology technology.
No.
SRS is a non-invasive radiation treatment.
There is no conventional surgical incision, no removal of the tumour with a surgical instrument and no open operation.
The name “radiosurgery” reflects the precision and high-dose nature of the treatment rather than the use of a surgical blade.
For some patients, this can mean a very different treatment experience from traditional neurosurgery.
However, SRS is still a serious medical treatment. It requires careful patient selection, detailed planning and appropriate follow-up.
SRS is particularly relevant to selected brain metastases.
A brain metastasis occurs when cancer that started elsewhere in the body spreads to the brain.
Depending on the number, size and location of the lesions, SRS may be considered as part of the patient's overall cancer treatment.
The decision can also depend on the type of primary cancer, whether disease is present elsewhere and what other treatments the patient is receiving.
SRS may also have a role in selected non-cancerous intracranial conditions, such as certain benign tumours.
For cancer patients, however, the treatment plan needs to be developed around the complete cancer history rather than focusing on the brain lesion alone.
Brain metastases can occur in patients with cancers such as lung cancer, breast cancer, melanoma and several other tumour types.
Treatment options may include surgery, SRS, whole-brain radiation therapy, systemic treatment or a combination of approaches.
SRS can be particularly useful when a lesion is well defined and appropriate for focused radiation.
The number of brain lesions is one factor doctors consider, but it is not the only factor.
Other important considerations include:
This is why two patients with apparently similar brain metastases may receive completely different treatment recommendations.
SRS is not exclusively a cancer treatment.
Selected benign intracranial tumours can also be treated with stereotactic radiation.
Examples may include:
Whether SRS is appropriate depends on the tumour's size, location, growth pattern and relationship with nearby structures.
For some patients, observation may be appropriate. For others, surgery may be preferred. Radiation may be considered in selected situations.
A consultation with the relevant specialist is therefore important before deciding on treatment.
The brain contains many delicate structures in a relatively small space.
A lesion may be close to the:
This makes treatment planning particularly important.
The radiation oncologist needs to determine how to deliver the prescribed dose while taking surrounding organs and tissues into consideration.
Venkateshwar Hospital's Neuro Oncology department describes a multidisciplinary team involving neurosurgeons, radiation oncologists and medical oncologists, supported by imaging and radiation technology including 3 Tesla MRI, PET-CT, CT and Versa HD radiation equipment.
This multidisciplinary approach can be particularly useful when treating complex brain tumours.
A patient's first appointment is usually not a treatment session.
There is a planning process.
The radiation oncologist reviews the patient's diagnosis, medical history and previous treatment.
MRI and other imaging studies are reviewed to understand the lesion's location and characteristics.
Depending on the treatment approach, imaging and positioning procedures are performed to establish the patient's treatment setup.
The treatment target is outlined, along with important surrounding structures that need to be protected.
A detailed plan is created to determine the direction, intensity and geometry of the radiation beams.
The plan is checked before treatment.
Once the plan has been approved, the patient is positioned and the radiation is delivered with image guidance as appropriate.
This preparation is one reason SRS should not be thought of as simply “one radiation session.”
The planning behind that session is a major part of the treatment.
The word SRS is commonly associated with single-session treatment.
However, stereotactic radiation can also be divided into multiple sessions in selected circumstances.
When stereotactic treatment is delivered over several sessions, it may be referred to as Stereotactic Radiotherapy (SRT) or fractionated stereotactic radiotherapy.
The choice between single-session SRS and multiple-session stereotactic treatment depends on factors such as:
Therefore, a patient should not assume that every SRS treatment will involve exactly one visit.
For appropriately selected patients, SRS offers several potential advantages.
The radiation is carefully directed toward a defined target.
There is no open surgical wound.
Some patients can complete stereotactic treatment in one session, while others may require a small number of sessions.
Modern imaging and computerised planning allow the treatment team to account for nearby structures.
In selected cases, a tumour may be located in an area where conventional surgery carries significant risks. SRS may be considered as an alternative or complementary treatment.
However, these benefits do not mean SRS is automatically the best option for everyone.
Sometimes it can be an alternative, but not always.
Surgery may be preferred when a tumour is large, causing significant pressure on the brain or when tissue needs to be obtained for diagnosis.
SRS may be considered for smaller, well-defined lesions in appropriate locations.
There are also cases where surgery and radiation are used together.
For example, a patient may undergo surgery to remove a larger lesion and subsequently receive focused radiation to the surgical cavity or another residual target.
The best approach depends on the individual diagnosis.
Both treatments use radiation, but their delivery can be quite different.
Conventional radiotherapy generally spreads the prescribed dose over a larger number of sessions.
SRS uses highly focused treatment to deliver a concentrated dose to a precisely defined target, often in one session.
The choice depends on the clinical situation.
A patient with multiple or extensive areas of disease may require a different radiation approach.
Similarly, a lesion that is too large or too close to a sensitive structure may not be suitable for single-session SRS.
SRS is designed to limit unnecessary exposure to healthy tissue, but side effects can still occur.
The risk depends on:
Some patients may experience fatigue, headache, nausea or temporary symptoms associated with swelling around the treated area.
Rare or delayed complications are also possible.
Patients should discuss the risks specific to their treatment plan with their radiation oncologist.
A general online description cannot predict how an individual patient will respond.
The radiation itself is not generally felt.
Because there is no conventional surgical incision, patients do not experience the type of pain associated with an open operation.
However, patients may experience discomfort from the positioning or immobilisation equipment used during treatment.
The treatment team explains the procedure beforehand and helps ensure that the patient is positioned appropriately.
Treatment does not necessarily end when the radiation session is over.
Follow-up is important.
Depending on the condition, the patient may require:
For patients with metastatic cancer, SRS is often one component of a broader treatment strategy.
The medical oncologist may continue chemotherapy, targeted therapy or immunotherapy depending on the primary cancer and overall treatment plan.
Yes, in selected cases.
Cancer treatment is increasingly multidisciplinary.
A patient may receive:
Surgery + SRS
or
Systemic therapy + SRS
or
SRS + other forms of radiation
depending on the diagnosis.
The timing of treatments matters, particularly when patients are receiving systemic therapies.
This is why communication between the radiation oncologist, medical oncologist, neurosurgeon and other specialists can be important.

Dr Mohit Kadian is listed as a Consultant in Radiation Oncology at Venkateshwar Hospital. The hospital's Radiation Oncology department lists him among its specialist team and identifies frameless Stereotactic Radiosurgery (SRS) as one of its specialised services.
For a patient considering SRS, however, choosing a doctor should involve more than searching for a treatment name.
The key question is whether the doctor can evaluate the complete clinical picture and determine whether SRS is appropriate.
This includes reviewing the patient's scans, diagnosis, previous treatment and the exact location and characteristics of the lesion.
If you have been referred for SRS, try to bring all relevant medical records.
These may include:
If possible, bring the actual imaging files rather than only the written reports.
The images can be important when the radiation oncologist is assessing whether a lesion is suitable for stereotactic treatment.
A consultation is an opportunity to understand why SRS has been recommended.
Ask what features of the tumour make it suitable for stereotactic treatment.
Understanding the alternatives helps you make an informed decision.
Ask about the proposed treatment schedule.
This can help explain the treatment planning process.
Ask about both short-term and delayed effects.
Ask when follow-up imaging is expected and what changes doctors will look for.
If you are receiving systemic treatment, ask how it will be coordinated with radiation.
SRS, or Stereotactic Radiosurgery, is a highly precise radiation treatment that delivers focused radiation to a defined target, particularly within the brain or skull base. It does not involve conventional surgery.
Yes. Venkateshwar Hospital in Dwarka lists frameless Stereotactic Radiosurgery (SRS) among its specialised Radiation Oncology services.
Yes. Dr Mohit Kadian is listed by Venkateshwar Hospital as a Consultant in Radiation Oncology.
No. SRS can also be used for selected benign brain and skull-base conditions. Its suitability depends on the specific diagnosis.
No. SRS is radiation treatment and does not involve a conventional surgical incision.
The radiation itself is generally not painful. Patients may experience some discomfort from positioning or immobilisation equipment.
Traditional SRS is generally associated with a single treatment session, but stereotactic radiation can also be delivered over several sessions in selected cases.
Yes. SRS can be considered for selected patients with brain metastases. The decision depends on the number, size and location of lesions, the primary cancer and the patient's overall condition.
Yes. In selected situations, focused radiation may be recommended after surgery to treat residual disease or the surgical cavity.
Yes. Side effects can occur, although the risks vary according to the treatment location, radiation dose, lesion characteristics and patient factors.
The radiation delivery may be relatively short, but the overall appointment can take longer because positioning and image verification are important parts of the procedure.
SRS generally refers to stereotactic radiation delivered in a single session, while SRT refers to stereotactic treatment delivered over multiple sessions.
It can be used alongside systemic cancer treatments in selected situations. The timing and combination should be decided by the treating oncology team.
For someone searching for SRS Therapy for Cancer Treatment in Dwarka, the availability of advanced technology is certainly important—but it should not be the only consideration.
SRS is a specialised treatment that depends heavily on accurate imaging, careful target definition, treatment planning, precise positioning and appropriate patient selection.
The right treatment may be SRS for one patient, surgery for another and conventional radiation or systemic treatment for someone else.
