Different types of Radiation Therapy, Cancer is a formidable adversary, affecting millions of lives worldwide. Fortunately, advances in medical science have given rise to a multitude of treatments, and radiation therapy stands as a powerful weapon in the oncologist’s arsenal. In this blog post, we’ll delve into the types of radiation therapy available to patients today. Whether you or a loved one is facing a cancer diagnosis, understanding these treatments can provide valuable insight into the options at your disposal.

External Beam Radiation Therapy

One of the most common types of radiation therapy is External Beam Radiation Therapy (EBRT). In EBRT, a machine directs high-energy X-ray beams or other types of radiation at the cancerous cells from outside the body. This non-invasive approach allows precise targeting of the tumour while minimising exposure to surrounding healthy tissues.

There are different types of radiation therapy, External Beam Radiation Therapy can be further divided into several subtypes. Image-guided radiation therapy (IGRT) employs imaging techniques like CT scans to ensure pinpoint accuracy in delivering radiation. Intensity-modulated radiation therapy (IMRT) refines the process even further by adjusting the intensity of the radiation beams to conform to the tumour’s shape, often reducing side effects.

Brachytherapy (Different Types of Radiation Therapy)

Brachytherapy, often referred to as internal radiation therapy, is one of the different types of radiation therapy. Unlike EBRT, where radiation comes from outside the body, brachytherapy involves placing a radioactive source directly inside or very close to the tumour. This approach offers a unique method for targeting cancer cells with radiation, and its utilisation depends on the specific circumstances and needs of the patient.

This method is highly effective for certain types of cancer, such as prostate, cervical, and gynaecological cancers. Various radiation therapy types of cancer treatments are available, and one of them is brachytherapy. The proximity of the radiation source in brachytherapy allows for a higher dose of radiation to be delivered to the tumour while sparing surrounding healthy tissues.

Brachytherapy can be administered temporarily, where the radiation source is removed after treatment, or permanently, where it remains in the body. It is essential for healthcare providers to determine the most suitable radiation therapy type based on the specific cancer diagnosis and individual patient needs.

Stereotactic Body Radiation Therapy (SBRT)

Stereotactic Body Radiation Therapy (SBRT) is a specialised form of external beam radiation therapy that delivers high doses of precisely targeted radiation in a few sessions. SBRT is commonly used for small, well-defined tumours in various parts of the body.

Different types of radiation therapy, one of the advantages of SBRT is its shorter treatment duration, often spanning just a few days, making it a suitable choice for patients with limited time or tolerance for a lengthy therapy course. The technique uses advanced imaging to pinpoint the tumour’s exact location, ensuring that radiation therapy is highly effective while minimising damage to healthy tissues. SBRT is frequently employed for lung, liver, and pancreatic cancers, among others.

Particle Therapy

Particle therapy, also known as proton therapy and carbon ion therapy, is a cutting-edge radiation treatment that employs charged particles like protons or carbon ions instead of traditional X-rays. These particles have the unique ability to deposit most of their energy precisely within the tumour, sparing healthy tissues.

There are different types of radiation therapy, Particle therapy is particularly advantageous for treating paediatric cancer patients, as it significantly reduces the risk of late effects and secondary cancers that can occur with traditional radiation therapy. Additionally, it can be highly effective for treating tumours located near critical organs, where minimising collateral damage is of paramount importance.

Combined Therapies and Emerging Trends

Different types of radiation therapy can be combined with other treatment modalities to achieve the best possible outcomes for patients. For instance, radiation therapy is frequently used in conjunction with surgery and chemotherapy to increase the chances of curing cancer or managing symptoms. This comprehensive approach underscores the importance of tailoring cancer treatment to the individual patient’s needs, considering various forms of radiation therapy to maximise the chances of successful outcomes.

Immunotherapy, a revolutionary treatment that harnesses the body’s own immune system to fight cancer, is also becoming a key player in the fight against various types of cancer. While there are different radiation therapy types of cancer treatments, radiation therapy can work in tandem with immunotherapy to enhance its effectiveness. This combination of treatment modalities can create a synergistic effect, offering new hope to patients with previously untreatable cancers. The integration of radiation therapy and immunotherapy showcases the evolving landscape of cancer treatment, providing innovative options for a wide range of cancer types.


Different types of radiation therapy offer a spectrum of options to cater to the diverse needs of cancer patients. From External Beam Radiation Therapy to Brachytherapy, Stereotactic Body Radiation Therapy, and Particle Therapy, each method has its unique strengths and applications. When dealing with cancer, knowledge is power, and understanding the various radiation therapy options is a significant step towards informed decision-making.

Frequently Asked Questions

External beam radiation therapy is a non-invasive treatment where a machine directs high-energy X-rays or other forms of radiation precisely at the tumour from outside the body. This method is used to treat a wide range of cancers and minimises damage to surrounding healthy tissue.

Brachytherapy is a type of radiation therapy where radioactive sources are placed directly inside or very close to the tumour. This localised treatment is effective for various cancers, such as prostate, cervical, and breast cancer. It delivers a high radiation dose while sparing nearby healthy tissue.

Proton therapy is a highly precise radiation treatment that uses charged particles called protons. It minimises damage to healthy tissue and is particularly useful for tumours near sensitive structures, like the brain and spinal cord. This therapy is an option for certain paediatric and adult cancers, providing excellent control and minimal side effects.
