What Patients Should Know Before Choosing a Specialist

A cancer diagnosis can change the atmosphere in a family almost overnight. Suddenly, medical reports, scans, pathology results and treatment options become part of everyday conversations. One of the questions that often comes up after a cancer diagnosis is: “Which radiation oncologist should we consult?”

For patients and families living in West Delhi, the search for the Best Radiation Oncologist in Dwarka is understandable. Radiation therapy can be an important part of cancer treatment, but it is also a highly specialised field. The right treatment depends on the type of cancer, its stage, location, previous treatment and the overall health of the patient.

In Dwarka, Dr Mohit Kadian is a Consultant in Radiation Oncology at Venkateshwar Hospital. His official hospital profile states that he has more than 10 years of experience in Radiation Oncology and is trained in modern radiation therapy techniques including IMRT, IGRT, VMAT, stereotactic SBRT, SRS and SRT.

But when someone searches for the “best” specialist, experience and technology are only part of the story. Patients also need a doctor who can explain the treatment clearly, understand the individual case and help them make informed decisions.

What does a radiation oncologist actually do?

A radiation oncologist is a doctor who specialises in treating cancer with radiation therapy.

Radiation can be used in different ways depending on the cancer. In some patients, it is intended to eliminate cancer cells as part of curative treatment. In others, radiation may be recommended after surgery to reduce the risk of cancer returning. It may also be combined with chemotherapy or other treatments.

For patients with advanced cancer, radiation can sometimes be used to control a tumour or relieve symptoms such as pain, bleeding or pressure caused by a tumour.

This means that radiation oncology is not simply about deciding how much radiation to give.

The radiation oncologist has to understand the complete clinical picture before recommending treatment.

That may include reviewing biopsy reports, pathology, CT scans, MRI, PET-CT, surgical records and previous cancer treatment.

Why the right specialist matters

There is no single radiation treatment that works for every cancer patient.

A person with breast cancer may have a completely different radiation plan from someone with prostate cancer. A patient with a head and neck tumour may require a different approach from someone with a lung or brain tumour.

Even two people with the same type of cancer can receive different radiation plans.

The reason is simple: the tumour may be in a different location, have a different size, be close to different organs or have responded differently to previous treatment.

A radiation oncologist therefore has to balance two objectives:

Treat the cancer effectively while protecting healthy tissues as much as reasonably possible.

This is where careful treatment planning becomes important.

Dr Mohit Kadian: Radiation Oncology in Dwarka

For people searching for the Best Radiation Oncologist in Dwarka, Dr Mohit Kadian is currently listed by Venkateshwar Hospital as a Consultant in Radiation Oncology. His listed qualifications are MBBS and MD. The hospital profile states that he completed his MBBS and MD at Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi.

According to the same profile, Dr Kadian previously worked in the Radiation Oncology department at Medanta – The Medicity, Gurugram, and has been involved in postgraduate teaching at Safdarjung Hospital. His profile also mentions publications in national and international journals and professional membership of the Association of Radiation Oncologists of India.

His stated training includes modern high-precision radiation techniques such as:

  • IMRT
  • IGRT
  • VMAT
  • Stereotactic SBRT
  • SRS
  • SRT

The significance of these techniques is not simply that they are technologically advanced. Their value lies in how they can be used in appropriate patients to plan and deliver radiation more precisely.

Understanding modern radiation therapy

Patients often hear terms such as IMRT, IGRT, VMAT or SRS during an oncology consultation and understandably wonder what they mean.

IMRT

Intensity-Modulated Radiation Therapy (IMRT) allows radiation intensity to be varied across different treatment fields.

The aim is to shape the radiation dose around the tumour while reducing unnecessary exposure to nearby healthy tissues where possible.

IGRT

Image-Guided Radiation Therapy (IGRT) incorporates imaging into the treatment process. Imaging can help the radiation team verify positioning and ensure that the treatment is delivered as planned.

VMAT

Volumetric Modulated Arc Therapy (VMAT) delivers radiation while the treatment machine rotates around the patient. The radiation dose and delivery parameters can be adjusted during the rotation.

SRS and SRT

Stereotactic techniques provide highly precise radiation treatment to selected targets, particularly in situations involving the brain and central nervous system.

SBRT

Stereotactic Body Radiation Therapy (SBRT) is used for selected tumours outside the brain. It delivers highly focused radiation over a relatively small number of treatment sessions.

Not every patient requires these techniques.

That is an important point to remember.

A good radiation oncologist does not select a technique simply because it is the newest option. The treatment has to make clinical sense for the individual patient.

What happens during the first consultation?

For many patients, the first oncology appointment can feel overwhelming.

There may be a lot of information to process, particularly if the diagnosis is recent.

A radiation oncology consultation generally involves understanding the patient's diagnosis and reviewing available medical records.

It is useful to carry:

  • Biopsy or pathology reports
  • CT scan reports and images
  • MRI reports and images
  • PET-CT reports, where applicable
  • Previous operation records
  • Chemotherapy records
  • Previous radiation therapy records
  • Recent blood investigations
  • Current medication details
  • Discharge summaries

If scans are available on a CD, USB drive or through an online medical imaging system, those should also be made available to the doctor.

The more complete the information, the easier it is for the radiation oncologist to understand the patient's treatment history.

Does every cancer patient need radiation?

No.

Radiation therapy is an important cancer treatment, but it is not required for every patient.

Whether radiation is recommended depends on the type and stage of cancer, the location of the tumour, the treatment objective and other individual factors.

For example, some cancers are primarily treated with surgery, while others may be treated with chemotherapy, targeted therapy, immunotherapy or hormone therapy. Radiation may be used alone or in combination with these treatments in selected situations.

This is why seeing a radiation oncologist does not necessarily mean that you will have to undergo radiation.

The purpose of the consultation is to determine whether radiation has a role in your treatment.

Radiation after surgery

Some patients are referred to a radiation oncologist after surgery.

The reason may be that the pathology report shows features suggesting that postoperative radiation could reduce the risk of cancer returning in the treated area.

The decision is based on the cancer type and individual pathological findings.

This is one reason patients should not assume that surgery means treatment is finished.

The pathology report can provide important information that influences the next stage of treatment.

Radiation with chemotherapy

In certain cancers, chemotherapy and radiation may be used together.

This is sometimes referred to as concurrent chemoradiation.

The purpose can be to improve the effectiveness of local treatment, although the exact approach depends on the disease.

Patients should ask their oncology team why combined treatment is being recommended and what side effects may occur.

Advanced radiation does not mean “no side effects”

One of the most common misconceptions about modern radiation therapy is that advanced technology completely eliminates side effects.

It does not.

Radiation can affect healthy tissues near the treatment area, and side effects vary according to the body part being treated.

For example, a patient receiving radiation to the head and neck may experience different effects from someone receiving treatment to the pelvis.

Fatigue is possible with radiation therapy, while other effects may include skin changes or symptoms related to the organs close to the treatment area.

Modern planning techniques are designed to improve precision and help manage radiation exposure to normal tissues, but every treatment still involves potential risks.

Your radiation oncologist should explain the side effects that are particularly relevant to your treatment.

How many radiation sessions are required?

This is one of the first questions most patients ask.

Unfortunately, there is no universal answer.

Some radiation courses involve treatment over several weeks. Selected patients may receive shorter schedules, including stereotactic treatments.

The number of sessions depends on:

  • Cancer type
  • Cancer stage
  • Tumour size
  • Tumour location
  • Treatment goal
  • Previous treatments
  • Radiation technique
  • Nearby organs and tissues

Therefore, a patient should be cautious about online claims that a particular cancer always requires a fixed number of sessions.

Your treatment schedule should be personalised.

Why location matters during cancer treatment

Cancer treatment is not always a one-day appointment.

Depending on the treatment plan, patients may need multiple visits for consultations, simulation, treatment planning, radiation delivery and follow-up.

This makes accessibility an important practical consideration.

For patients living in Dwarka Sector 6, Sector 10, Sector 12, Sector 13, Sector 17, Sector 18 and Sector 18A, seeking oncology care within Dwarka can reduce some of the travel involved.

The same can apply to patients coming from nearby areas such as Palam, Dabri, Janakpuri, Uttam Nagar, Vikaspuri and Najafgarh.

Venkateshwar Hospital is located in the Sector 18/18A area of Dwarka, New Delhi.

A local Dwarka-based oncology consultation can therefore be particularly convenient for patients who may need repeated hospital visits.

What should you look for when choosing a radiation oncologist?

If you are comparing specialists, consider more than online rankings.

Qualifications

Look for appropriate medical qualifications and specialist training in Radiation Oncology.

Relevant experience

Experience with the type of cancer being treated can be important.

Treatment planning expertise

Modern radiation therapy requires detailed planning. Ask about the techniques relevant to your diagnosis.

Communication

Instead, focus on practical questions:

Why do I need radiation?

Understanding the purpose of treatment is the first step.

What will radiation achieve?

Ask whether the goal is cure, reducing recurrence risk, controlling the tumour or relieving symptoms.

Which radiation technique will you use?

Ask why that particular technique has been selected.

How many sessions will I need?

Ask for an approximate treatment schedule.

What side effects should I expect?

Ask about both short-term and possible long-term effects.

Will I need other treatments?

Radiation may be part of a larger treatment plan.

How will we know whether the treatment has worked?

Ask about follow-up imaging and clinical evaluation.
