What is Radiation Therapy?

Radiotherapy or radiation therapy is a crucial medical treatment used in the management of various diseases, primarily cancer. This therapy employs high-energy radiation to target and destroy cancer cells or to shrink tumors. 

Why is Radiation Therapy Done?

Radiation therapy is performed for several reasons. Radiation therapy in Chennai is done for the following purposes:

1. Cancer Treatment: The primary goal of radiation therapy is to treat cancer. It can be used as the sole treatment method or in combination with surgery, chemotherapy, or immunotherapy, depending on the type and stage of cancer. Radiation therapy is often chosen when cancer is localized or when surgery is not an option.

2. Tumor Shrinkage: Radiation therapy can be used before surgery to shrink tumors, making them easier to remove. This is known as neoadjuvant therapy.

3. Palliative Care: In cases where cancer cannot be completely cured, radiation therapy can provide palliative care. It helps alleviate symptoms and improve the quality of life by reducing tumor size and relieving pain and discomfort at an affordable radiation therapy cost in Chennai.

4. Adjuvant Therapy: After surgery to remove a tumor, radiation therapy may be administered to destroy any remaining cancer cells and reduce the risk of cancer recurrence.

Procedure of Radiation Therapy

The process involved for radiation therapy in Chennai typically involves several steps including:

Consultation and Planning

The process begins with a consultation with a radiation oncologist, who specializes in radiation therapy. During the radiation therapy in Chennai, an oncologist reviews the patient’s medical history, conducts physical examinations, and assesses diagnostic imaging such as CT scans and MRI. A treatment plan is then developed based on the cancer type, stage, location, and the patient’s overall health.


During simulation, the patient is positioned precisely on the treatment table to ensure accurate targeting of the tumor. Immobilization devices like molds or masks may be used to keep the patient in the same position for each treatment session. Imaging techniques such as CT or MRI scans are performed at a reasonable radiation therapy cost in Chennai to map the tumor’s exact location.

Treatment Planning

Using the simulation data, the radiation oncology team calculates the optimal radiation dose and treatment angles to maximize the dose to the tumor while sparing surrounding healthy tissue. Advanced computer software is employed to design the treatment plan.

Radiation Delivery

Radiation therapy in Chennai can be delivered in various ways, including external beam radiation and internal radiation (brachytherapy). External beam radiation is the most common method, involving a machine called a linear accelerator that directs radiation beams at the tumor from various angles. The patient typically receives treatments over several weeks, with daily sessions lasting only a few minutes.

Benefits of Radiation Therapy in Chennai

There are various benefits of radiation therapy in Chennai. They include:

  • Targeted Treatment: Radiation therapy precisely targets the tumor, minimizing damage to nearby healthy tissue.
  • Curative Potential: Radiation therapy can cure cancer in some cases, especially when the disease is localized.
  • Palliative Care: For advanced cancers, radiation therapy can significantly improve the patient’s quality of life by reducing pain and other symptoms.
  • Combined Therapy: It can be used in conjunction with surgery and chemotherapy to increase treatment effectiveness.
  • Non-Invasive: Unlike surgery, radiation therapy is a non-invasive treatment option making the radiation therapy cost in Chennai cost-effective. 

Risks and Side Effects

Radiation therapy in Chennai is an effective cancer treatment, but it does come with potential risks and side effects that include:

Advanced Radiation Therapy Techniques

  • Stereotactic Radiosurgery (SRS): Precisely targets small brain tumors or abnormalities in a single, high-dose session.
  • Stereotactic Body Radiation Therapy (SBRT): Delivers highly focused radiation to extracranial tumors, completing treatment in a few sessions.
  • Proton Therapy: Utilizes protons instead of photons for precise cancer targeting, reducing damage to surrounding healthy tissues.
  • Intensity-Modulated Radiation Therapy (IMRT): Adjusts radiation beam intensity in multiple directions, customizing doses to the tumor’s shape.
  • Image-Guided Radiation Therapy (IGRT): Incorporates imaging during treatment to enhance accuracy and adjust for patient positioning changes.
  • Volumetric Modulated Arc Therapy (VMAT): Optimizes radiation delivery with continuous motion, improving treatment efficiency and precision.

Results and Follow-up

The effectiveness of radiation therapy in Chennai varies depending on factors such as the type and stage of cancer. Some expected outcomes include:

  • Tumor Shrinkage: In many cases, radiation therapy leads to a reduction in tumor size.
  • Pain Relief: Patients often experience reduced pain and improved overall well-being.
  • Cure: Radiation therapy can lead to a complete cure in some cases, especially when cancer is localized.
  • Adjunct to Other Therapies: It complements surgery and chemotherapy by targeting residual cancer cells.
  • Long-term Monitoring: After treatment, patients are closely monitored to assess the treatment’s success and manage any side effects or complications.


To conclude, radiation therapy in Chennai at Vinita Hospital offers curative potential and enhanced quality of life for advanced cases. While it presents risks and side effects, its benefits usually outweigh them, when part of a comprehensive plan.

Radiation therapy, also known as radiotherapy, is a medical treatment that uses high-energy radiation to target and destroy cancer cells. Radiation therapy can be categorized into three primary types:

External Beam Radiation Therapy (EBRT):

  • In EBRT, a machine called a linear accelerator directs high-energy X-rays or other types of radiation (such as protons) from outside the body toward the tumor.
  • The patient typically undergoes daily treatments over the course of several weeks, with each treatment session lasting only a few minutes.
  • The radiation is carefully calculated and aimed to maximize its effect on the tumor while minimizing damage to surrounding healthy tissue.

Internal Radiation Therapy (Brachytherapy):

  • Brachytherapy involves the placement of a radioactive source directly inside or very close to the tumor.
  • This allows for the delivery of a high dose of radiation to the tumor while sparing nearby healthy tissues.
  • Brachytherapy can be used in various forms, such as intracavitary (within body cavities like the uterus or esophagus), interstitial (within tissues), or surface applications.

Systemic Radiation Therapy:

  • Systemic radiation therapy involves the use of radioactive substances that can be taken orally or intravenously.
  • These radioactive drugs, also known as radiopharmaceuticals, are absorbed by cancer cells throughout the body.
  • This treatment is primarily used for certain types of metastatic cancers, where cancer has spread to multiple locations in the body.

The success rate of radiation therapy varies widely depending on several factors, including the type and stage of cancer, the location of the tumor, the overall health of the patient, and the effectiveness of the radiation treatment plan. It’s important to note that success in radiation therapy is typically measured in terms of its ability to achieve specific treatment goals, which may include:

  • Cure: In some cases, radiation therapy can be curative, meaning it completely eliminates the cancer. The success rate in achieving a cure depends on the type of cancer and its stage at the time of diagnosis. Certain early-stage cancers, such as some skin cancers and early-stage prostate cancer, can have high cure rates with radiation therapy.
  • Local Control: Radiation therapy is often used to control or shrink tumors, even if a complete cure is not possible. Success in this context means preventing the tumor from growing or causing symptoms. The success rate for local control can vary widely depending on the cancer type and stage but is generally high for many cancers.
  • Palliation: In cases where cancer is advanced and a cure is not feasible, radiation therapy can be used to relieve symptoms, such as pain, bleeding, or obstruction. Success in palliative radiation therapy means improving the patient’s quality of life and providing relief from cancer-related symptoms.
  • Adjuvant or Neoadjuvant Therapy: Radiation therapy is sometimes used in combination with surgery or other treatments. Success in this context means enhancing the effectiveness of other treatments and improving overall outcomes.

Radiation treatment itself is generally not painful. During a radiation therapy session, the patient typically lies still on a treatment table, and the radiation machine is carefully calibrated to target the cancerous cells while minimizing exposure to healthy surrounding tissues.

However, there are some potential side effects associated with radiation therapy, and these side effects can vary depending on several factors, including the type and location of the cancer, the dose of radiation, the duration of treatment, and the individual’s sensitivity to radiation. Here are some typical side effects that can occur as a result of radiation therapy:

  • Fatigue: Many patients experience fatigue during and after a course of radiation therapy. This fatigue can range from mild to severe and may be cumulative over the course of treatment.
  • Skin Changes: Radiation can cause skin reactions in the treatment area, such as redness, itching, and peeling. In some cases, the skin may become more sensitive or tender.
  • Hair Loss: If the radiation is targeted at an area with hair, such as the head or face, temporary hair loss in the treatment area may occur.
  • Swelling: Radiation therapy can cause localized swelling, especially if it’s used near or on a limb.
  • Nausea and Digestive Issues: Depending on the location of the radiation treatment, some patients may experience nausea, vomiting, or digestive discomfort.
  • Changes in Appetite: Radiation to the head and neck area can affect a person’s ability to swallow or taste food, potentially leading to changes in appetite.
  • Long-Term Effects: In some cases, radiation therapy may result in long-term side effects, such as changes in the function of the treated organ or an increased risk of developing other health issues in the future.
