Radiation Therapy: How It Works and What to Expect During Treatment

When someone mentions radiation therapy, often a cloud of uncertainty and fear starts to form. The term itself seems laden with daunting implications, especially if it’s part of a treatment conversation. However, radiation therapy is a well-established, effective method used for treating various types of cancer and some non-cous conditions. In this blog post, I’ll demystify the workings of radiation therapy and guide you through what to expect during the treatment process, especially tailored for readers in India.

Understanding Radiation Therapy

Radiation therapy, also known as radiotherapy, is a type of cancer treatment that utilizes high doses of radiation to kill cancer cells and shrink tumors. At its core, the principle is to use radiation to damage the DNA of cancer cells, which ultimately leads to cell death or hinders the cells’ ability to reproduce.

Types of Radiation Therapy

Radiation therapy can be categorized into two main types:

1. External Beam Radiation Therapy (EBRT): This is the most common form where a machine outside the body directs radiation towards cancer. The technology can tailor the radiation beams to the shape of a tumor, which minimizes the damage to surrounding healthy tissues. In India, machines like Linear Accelerators (LINAC) are commonly used for this purpose.
2. Internal Radiation Therapy (Brachytherapy): This involves placing a radioactive material inside your body near the cancer cells. It’s often used for cancers of the cervix, prostate, and breast. This method delivers a high dose of radiation to a small area, which means it’s less likely to affect healthy tissues.

How It Works: The Science Behind The Therapy

At a microscopic level, radiation therapy works by breaking the DNA of cells. This breakage prevents cancer cells from growing and dividing, eventually causing them to die. Importantly, the body naturally removes these dead cells. Radiation is particularly effective on rapidly dividing cells, such as cancer cells, but it can also affect normal cells leading to side effects.

What to Expect During Radiation Therapy

Undergoing radiation therapy can be a stress-inducing experience, filled with numerous doctor visits and unfamiliar medical terms. Here’s a breakdown of what to expect during the different phases of this treatment:

Before Treatment

• Consultation with Radiation Oncologist: Initially, you’ll meet a specialist who will review your medical records, perform a physical exam, and discuss the appropriateness of radiation therapy for your cancer type.
• Simulation: Before the actual treatment starts, a ‘simulation’ of the treatment is done. During this, imaging studies such as CT scans are used to determine the precise location and shape of the tumor. You might be asked to lie still on a table while a technician uses a machine to define your treatment fields.

During Treatment

• Treatment Sessions: Radiation therapy is usually given over several sessions. The number of sessions depends on the total dose required, and therapy is often administered over several weeks.
• Daily Routine: Each session typically lasts for 15 to 30 minutes, during which you must lie still under the radiation machine. The process itself is painless – radiation feels like getting an X-ray.
• Safety Measures: The therapy rooms are built to contain radiation; hence, there is no risk of radiation exposure to others from being near you after treatment.

Managing Side Effects

Radiation therapy can cause side effects, which vary depending on the treatment area. Some common side effects include fatigue, skin changes at the site of treatment, and loss of appetite. Here are some tips to manage them:

• Skin Care: Treat the skin exposed to radiation with gentle care. Use mild soap, avoid sun exposure, and consult your oncologist before applying any creams or ointifers.
• Nutrition: Maintaining adequate nutrition can help you cope with side effects like fatigue and loss of appetite. A dietitian can guide you to an appropriate diet plan.
• Rest: Listen to your body. If you feel tired, rest. It’s essential in helping your body recover during treatment cycles.

After Treatment

Following the completion of radiation therapy, regular follow-ups with your radiation oncologist are necessary. These visits are vital to monitor your recovery and manage any long-term side effects. Recovery time can vary greatly among individuals, depending on the treatment specifics and personal health.

Conclusion

Radiation therapy might sound intimidating, but it’s a sophisticated treatment modality backed by decades of research. Understanding its mechanics and what to expect can profoundly demystify the process and ease the anxiety associated with such treatments. If you or a loved one is about to undergo radiation therapy, remember that it’s okay to ask questions and seek support. Forming a comprehensive understanding of the therapy will not only prepare you for the journey ahead but also empower you to face it with resilience.

Remember, each step forward in treatment is a step toward recovery. Let education be your guide and support your path through this experience. For more detailed information or personal stories, consider joining support groups or consulting your health care provider. Every question asked is a leap closer to understanding and peace.
