Radiation therapy is a cornerstone in cancer treatment, offering precise and effective options to target tumours and improve patient outcomes. It uses high-energy particles or waves to destroy cancer cells while minimising harm to healthy tissues. With advancements in technology, radiation therapy can treat a wide range of cancers, either alone or in combination with other treatments like surgery or chemotherapy. This article serves as a guide to understanding how radiation therapy works, the types of cancers it treats, and what patients can expect during their journey.

What is Radiation Therapy?

Radiation therapy uses high-energy particles or waves, such as X-rays, gamma rays, or protons, to target and destroy cancer cells. By damaging the DNA of these cells, radiation prevents them from growing, dividing, and spreading. While it affects both cancerous and healthy cells, advancements in technology ensure minimal harm to surrounding tissues.

Types of Radiation Therapy

External Beam Radiation Therapy (EBRT): This type involves a machine, such as a linear accelerator, that directs radiation beams toward the tumour.

Intensity-Modulated Radiation Therapy (IMRT): Shapes radiation beams to match the tumour’s size and structure.
Image-Guided Radiation Therapy (IGRT): Uses imaging to improve precision.
Stereotactic Body Radiotherapy (SBRT): Delivers high doses in fewer sessions, commonly used for lung, liver, and brain cancers.

Internal Radiation Therapy (Brachytherapy): In this method, doctors place radioactive seeds, ribbons, or capsules inside or near the tumour. Brachytherapy is commonly used for prostate, cervical, and breast cancers.

Systemic Radiation Therapy: Patients swallow or receive injections of radioactive substances that travel through the bloodstream. This method effectively treats thyroid cancer and certain types of lymphoma.

How Does Radiation Therapy Treat Different Cancers?

Radiation therapy can treat various types of cancer, either as a standalone option or in combination with surgery, chemotherapy, or immunotherapy.

Breast Cancer: EBRT targets remaining cancer cells after surgery, reducing the risk of recurrence.
Lung Cancer: SBRT works well for small, localised tumours, while IMRT handles larger areas.
Prostate Cancer: Brachytherapy is highly effective, offering a focused treatment with minimal impact on surrounding tissues.
Head and Neck Cancers: Radiation therapy helps preserve critical functions like speech and swallowing by precisely targeting tumours.
Cervical and Endometrial Cancer: Brachytherapy treats localised tumours, often combined with external radiation.

The Treatment Process: What Patients Need to Know

Consultation and Planning

Patients meet with an oncologist and a radiation therapist to discuss their diagnosis and create a personalised treatment plan. Imaging techniques like CT, MRI, or PET scans map the tumour and surrounding tissues.

Simulation

During this step, specialists determine the optimal position for treatment. Patients may undergo a simulation session, where markers or moulds are used to ensure consistent positioning.

Treatment Sessions

External treatments typically last 15–30 minutes per session.
Internal therapy involves placing radioactive material, which may stay in the body temporarily or permanently.
Systemic therapy involves an oral or intravenous dose of radioactive material.

Follow-Up Care

Post-treatment, regular check-ups monitor progress, manage side effects, and address any concerns.

Managing Side Effects

Radiation therapy may cause side effects, depending on the treatment area and dose. Common issues include:

Skin Changes: Redness, dryness, and peeling.
Fatigue: Resulting from the body's repair processes.
Localised Pain or Swelling: Particularly in areas like the neck or abdomen.

To manage these effects:

Follow a skincare routine with gentle, non-irritating products.
Maintain a balanced diet to support recovery.
Discuss medications or therapies to alleviate pain and discomfort.

Advancements in Radiation Therapy

Modern techniques have improved radiation therapy’s effectiveness while minimising side effects:

Proton Therapy: Uses protons instead of X-rays, offering greater precision and reducing exposure to surrounding healthy tissues.
Adaptive Radiation Therapy: Adjusts treatment plans based on daily imaging results, ensuring accurate targeting.
FLASH Radiation Therapy: A promising innovation that delivers ultra-high doses in microseconds, potentially reducing side effects.

Emotional and Psychological Support for Patients

Cancer treatment extends beyond physical care. Patients often face anxiety, fear, and uncertainty during their journey. Open communication with medical teams, support groups, and counselling can help manage these emotions. Building a support network of family and friends plays a crucial role in emotional well-being.

Myths and Facts

Myth 1: Radiation therapy cures all types of cancer.
Fact: Radiation therapy is highly effective for many cancers but is often used alongside surgery, chemotherapy, or immunotherapy for the best outcomes.

Myth 2: Radiation therapy is always painful.
Fact: Radiation therapy itself is painless. Any discomfort usually stems from side effects like skin irritation, which vary between patients.

Myth 3: Radiation therapy only targets cancer cells.
Fact: Radiation therapy primarily targets cancer cells but may also affect nearby healthy cells. Advances in technology minimise damage to healthy tissue.

Myth 4: Once radiation therapy begins, treatment cannot be adjusted.
Fact: Doctors regularly monitor your response to radiation and can modify treatment plans as needed to improve effectiveness or reduce side effects.

Myth 5: You can’t work or perform daily activities during radiation therapy.
Fact: Many patients continue their usual routines with adjustments, though energy levels and other factors might require some accommodation.

Did You Know?

Radiation therapy contributes to the treatment of more than 50% of cancer patients, making it one of the most widely used cancer treatments worldwide.
Proton therapy can reduce radiation exposure to surrounding tissues by up to 60%, especially in cancers near critical organs like the brain or spine.

Conclusion

Radiation therapy offers a powerful weapon against cancer, tailored to individual needs and tumour types. Understanding the process and maintaining open communication with healthcare providers ensures patients feel informed and prepared. With technological advancements and a focus on comprehensive care, radiation therapy continues to improve outcomes for patients facing various cancers.
