Table of Contents

Cancer. Just the word itself can instil fear and uncertainty. But amidst the whirlwind of emotions, knowledge is power. When radiotherapy becomes part of your treatment plan, understanding its purpose, potential side effects, and financial considerations becomes crucial.

Radiotherapy plays a crucial role in battling cancer, both alone and in conjunction with other treatments. In this article, we’ll break down radiotherapy to give you a clearer understanding of what exactly the treatment entails, what cancers it can treat and more.

Radiotherapy involves directing high-energy beams straight at cancer cells, crippling their ability to grow and multiply. It utilises ionising radiation, such as X-rays, gamma rays, or protons, to damage cancer cells’ DNA, ultimately destroying them. This treatment is precise, targeting the tumour area while minimising harm to healthy tissues.

Here is a brief history of radiotherapy to help you understand how radiotherapy for cancer came into existence.

Inception:

1895: Wilhelm Conrad Roentgen accidentally discovers X-rays while experimenting with cathode rays. He dubs them “X-rays” due to their unknown nature.
1896: Within months, X-rays are used to treat skin conditions and, remarkably, even tumours. This marks the very first usage of radiation for medical purposes.

Exploration and Refinement:

Late 1890s: Marie and Pierre Curie discovered radium, another radiation source. Its potential for medical use, including cancer treatment, is quickly recognised.
Early 1900s: Pioneering physicians experimented with X-rays and radium, initially using crude applicators and often facing unintended side effects due to a limited understanding of radiation dosage and effects.
1920s-1950s: Advances in technology and understanding of radiation biology propel radiotherapy forward. Higher-energy X-ray machines and safer delivery methods have emerged.

Evolution and Specialisation:

1950s-1960s: Linear accelerators revolutionise radiotherapy with more precise and powerful beams. Cobalt-60 therapy becomes a mainstay.
1970s-1980s: Imaging techniques like CT scans improve targeting accuracy, paving the way for conformal radiotherapy that minimises damage to healthy tissues.
Present Day: Continuous advancements in technology and research bring forth diverse forms of radiotherapy, like brachytherapy, proton therapy, and stereotactic radiosurgery, offering even more targeted and effective treatment options.

Radiotherapy for Cancer

Radiotherapy for cancer developed gradually, not as a single invention but through continuous exploration and refinement by various scientists and physicians. X-rays and radium were the initial driving forces, followed by technological advancements and an understanding of radiation biology. Today, radiotherapy continues to evolve with new techniques and applications, offering greater hope and precision in cancer treatment.

Adjuvantly: To reduce the risk of cancer recurrence after other treatments like surgery or chemotherapy.
Palliatively: To alleviate pain and other symptoms caused by advanced cancer, improving quality of life.

There are various types of radiotherapy for cancer, each tailored to target specific tumours with precision and effectiveness. Let’s dive deeper into the versatility of radiotherapy:

Types:

Conformal radiotherapy: The radiation beam is adjusted to match the tumour shape precisely, minimising damage to surrounding healthy tissues.
Intensity-modulated radiotherapy (IMRT): Varies the radiation beam’s intensity within the tumour area, further minimising healthy tissue exposure.
Image-guided radiotherapy (IGRT): Uses real-time imaging during treatment to ensure accurate targeting and adjust if needed.

Beyond External Beams:

Brachytherapy places radioactive sources directly inside or near the tumour for a highly concentrated dose. It minimises radiation exposure to healthy tissues and is often used for cancers like cervix, prostate, and head and neck cancers.
Radioembolisation injects radioactive particles into blood vessels feeding the tumour, delivering targeted radiation from within. This is used for certain liver cancers and other tumours with specific blood supply characteristics.

Targeting Specific Cancers:

Proton therapy: Utilises protons, charged particles, which deliver their radiation dose more precisely within the tumour and less to surrounding tissues. This is particularly beneficial for treating tumours close to critical organs or in children, as their bodies are still developing.
Stereotactic radiosurgery (SRS): In this, a high dose of radiation is used in a single or few sessions with extreme precision, often used for small, inoperable tumours in the brain or other body parts.

Combined Efforts:

Radiotherapy often works hand-in-hand with other cancer treatments like –

Surgery: Shrinking tumours before surgery or eliminating microscopic remnants after surgery.
Chemotherapy: Enhancing the effectiveness of chemotherapy drugs or reducing side effects.
Immunotherapy: Boosting the immune system’s ability to fight cancer cells.

Expanding the Scope:

Beyond cancer: Radiotherapy can also treat non-cancerous conditions like benign tumours, keloids, and certain eye diseases.
Research frontiers: Ongoing research investigates the use of radiotherapy in combination with new drugs and technologies, further personalising treatment and improving outcomes.

Radiotherapy is a multifaceted treatment that can be used to treat cancer. Its precision, versatility, and ability to work synergistically with other modalities make it a crucial tool in the hands of oncologists, offering hope and improved outcomes for countless patients.
