Cancer Treatment With Radiation Therapy

How Does Radiation Therapy Work?

Radiation therapy is the foundation of modern cancer treatment. It employs high-energy particles or waves to target and destroy cancer cells, by carefully directing radiation to cancerous areas. This therapy aims to minimise damage to surrounding healthy tissues. Types of radiation therapy, such as external beam radiation and brachytherapy, utilise different technologies to achieve precise results. Advances like image-guided radiation therapy and intensity-modulated radiotherapy further enhance the accuracy and effectiveness of treatments.

How do Oncologists use Radiation Therapy?

Oncologists, or radiation oncologists specifically, use radiological imaging techniques to plan and deliver radiation therapy made for each patient’s unique cancer profile. This meticulous planning ensures the radiation dose maximally impacts the cancer cells while sparing normal tissues as much as possible. Techniques such as intensity-modulated radiotherapy allow oncologists to modulate the radiation dose, adapting the intensity to the shape and size of tumours.

Types of Radiation Therapy

Radiation therapy, a pivotal component of radiation oncology, encompasses several types designed to cater to different cancer treatment scenarios.

1.External Beam Radiation Therapy (EBRT): This is the most prevalent form of radiation oncology. Utilising advanced cancer treatment machinery, EBRT directs high-energy rays from outside the body directly to the cancerous tissues. It is versatile and can be adapted for various types of cancer, making it a fundamental technique in radiation oncology treatment.

2. Brachytherapy: Known for its efficacy in treating cancers close to the skin or in body cavities, brachytherapy involves implanting radioactive sources directly into or near the tumour. This method minimises exposure to healthy tissues and is commonly used for cancers of the prostate, cervix, and breast. It is a prime example of targeted radiation therapy types.

3.Stereotactic Radiotherapy: This technique is especially beneficial for treating small, well-defined tumours in the brain and other parts of the body. It can deliver radiation with pinpoint accuracy, which is crucial for minimising damage to surrounding healthy tissues. This form of therapy showcases the sophistication of radiological imaging techniques used in radiation oncology.

4.Proton Therapy: Unlike traditional radiation therapy which uses X-rays, proton therapy employs protons to treat cancer. The primary advantage of proton therapy is its ability to deliver precise conical beams that deposit the bulk of their energy directly in the tumour, reducing the radiation therapy cost in terms of side effects and damage to nearby healthy tissues.

Each of these radiation therapy types plays a critical role in advanced cancer treatment, offering options curated to the patient’s specific needs.

Benefits of Radiation Therapy in Cancer Treatment

Radiation therapy offers several significant benefits that make it a foundation of modern cancer care:

1. Targeted Treatment: One of the most significant advantages of radiation therapy, particularly in techniques like brachytherapy and proton therapy, is its ability to precisely target tumours. This precision is vital for preserving healthy tissues and is a core principle of radiation oncology.

2. Versatility: Radiation therapy is remarkably versatile, able to be used as a standalone treatment or in combination with other treatments such as surgery and chemotherapy. This adaptability makes it applicable to a wide range of cancers and stages, enhancing its role in radiation therapy. 

3. Palliation: For advanced cancers, radiation therapy can be used to relieve symptoms, such as pain or obstruction, thus improving the quality of life for patients. This soothing aspect is crucial in radiation therapy treatment. Radiation therapy treatment in Agartala, Tripura is gaining a lot of popularity.  

4. Cost-effectiveness: While radiation therapy cost may vary, the ability to target specific areas reduces long-term costs associated with side effects and secondary treatments. Technologies like image-guided radiation therapy enhance this cost-effectiveness by improving accuracy.

Side Effects And Management

While radiation therapy is a potent tool against cancer, it comes with potential side effects such as fatigue, skin changes, and more specific issues depending on the treatment area. These effects can often be managed through coordinated care approaches, including skincare routines, nutritional guidance, and sometimes medications to alleviate symptoms.

Radiation therapy remains a critical element in the fight against cancer, offering hope and healing through advanced technological treatments. By understanding both its power and its challenges, patients and their families can better navigate the complexities of cancer care.


  • What does radiation therapy do to the body?

    During radiation therapy, targeted radiation is used to destroy cancer cells. The procedure can cause side effects like fatigue and localised skin changes, depending on the treatment area.

  • Is radiation therapy considered safe?

    Radiation therapy is a widely used and generally safe treatment for cancer. It usually has its safety measures in place to minimise risks and side effects.

  • Can you maintain a normal life during radiation therapy?

    Many patients continue their daily routines while undergoing radiation therapy, although adjustments may be needed based on energy levels and side effects. Nutrition plays a vital role during the process. 

  • What should you avoid eating during radiation therapy?

    It is advisable to avoid high-fat, spicy, or fibrous foods that may irritate the system during radiation therapy. A focus on mild, nutritious foods can help manage side effects.

  • What are the common side effects of radiation therapy?

    The two most prevalent side effects of radiation therapy are skin irritation around the treatment area and fatigue. They can be managed with appropriate care.
