When you hear the term radiation therapy, you may immediately think of cancer treatment. While it’s commonly associated with oncology, radiation therapy is used to treat a variety of conditions, including benign (non-cancerous) tumors, as well as certain types of cancer. But what exactly is it, and how does it work?
If you’re facing a medical situation where radiation therapy might be recommended, you likely have a lot of questions. In this post, we’ll break down everything you need to know about radiation therapy treatment, its purpose, the types available, and how a radiation oncologist in Hyderabad can help you through the process.
What is Radiation Therapy?
Simply put, radiation therapy is a medical treatment that uses high-energy radiation to target and destroy abnormal cells in the body. The most common use of radiation therapy is in the treatment of cancer. It works by damaging the DNA inside the targeted cells, preventing them from growing and dividing, which ultimately causes the cells to die off.
While it’s mostly used for cancer treatment, radiation therapy can also shrink tumors, treat non-cancerous growths, and even relieve pain associated with certain conditions like bone metastasis.
How Does Radiation Therapy Work?
Radiation therapy can be delivered in two main ways:
External Beam Radiation – This is the most common form of radiation therapy. It’s delivered from outside the body using a machine called a linear accelerator. The patient typically lies on a treatment table, and the machine is aimed at the tumor or area requiring treatment.
Internal Radiation Therapy (Brachytherapy) – In this approach, radiation sources are placed directly inside or very close to the tumor. This is commonly used for cancers of the prostate, cervix, and certain head and neck cancers.
Both methods are designed to target cancerous cells while minimizing damage to the surrounding healthy tissue.
Why is Radiation Therapy Used?
Radiation therapy is used to treat a variety of medical conditions, including:
Cancer Treatment: Radiation therapy is used to shrink tumors or destroy cancer cells. It may be used alone or in combination with other treatments like surgery, chemotherapy, or immunotherapy.
Palliative Care: In cases where cancer has spread and is no longer curable, radiation therapy can help reduce symptoms and improve quality of life by relieving pain, bleeding, or obstruction caused by tumors.
Pre-surgical Treatment: In some cases, radiation therapy may be given before surgery to shrink a tumor, making it easier to remove.
Post-surgical Treatment: Radiation may also be used after surgery to kill any remaining cancer cells that were not removed during the operation.
Types of Radiation Therapy
There are several types of radiation therapy, each serving a different purpose. Some of the most common include:
Intensity-Modulated Radiation Therapy (IMRT): A sophisticated form of external beam radiation therapy that allows doctors to shape the radiation beams to closely match the tumor’s shape, delivering precise doses of radiation to the tumor while sparing nearby healthy tissue.
Stereotactic Body Radiotherapy (SBRT): This is a high-precision form of radiation therapy that is typically used for treating small, well-defined tumors. It involves delivering very high doses of radiation to the tumor in fewer treatment sessions.
Proton Therapy: This type of therapy uses protons rather than X-rays to treat cancer. Proton therapy is especially useful for tumors located near vital organs or in children, as protons can be more precisely controlled.
Brachytherapy: This is used primarily for cancers of the prostate, cervix, and head and neck. The radiation source is placed directly inside or near the tumor, delivering a high dose of radiation to the cancer while minimizing exposure to healthy tissues.
What Should You Expect During Radiation Therapy?
If you or a loved one is preparing for radiation therapy, it’s natural to wonder what the process will be like. Here’s what to expect during your treatment journey:
Consultation and Planning: Your radiation oncologist in Hyderabad will first conduct a thorough assessment of your condition, including imaging tests like CT scans or MRIs to map out the precise location of the tumor. This helps to plan the most effective treatment approach.
Treatment Sessions: External beam radiation therapy usually involves daily treatments (5 days a week) for several weeks, depending on your condition. Each session lasts only a few minutes, but the setup time may be longer as the radiation oncologist ensures that the machine is properly aligned.
Post-Treatment Care: After each session, you can return home and resume normal activities. However, it’s important to follow any instructions from your doctor regarding skin care, hydration, and avoiding infections. Depending on the type of treatment, side effects may occur, which can be managed by your healthcare team.
Monitoring Progress: During and after your treatment, your radiation oncologist will monitor your progress through regular follow-up appointments and scans to ensure that the treatment is working effectively.
Benefits of Radiation Therapy
Localized Treatment: Radiation targets specific areas of the body, which allows it to be highly effective for treating localized cancers or tumors.
Minimized Side Effects: Modern techniques like IMRT and proton therapy allow for precise targeting, reducing the risk of damage to surrounding healthy tissues.
Complementary to Other Treatments: Radiation therapy can be used in conjunction with surgery or chemotherapy to improve outcomes and reduce the chance of cancer recurrence.
Side Effects of Radiation Therapy
While radiation therapy is highly effective, it can cause side effects, which vary depending on the treatment area. Some common side effects include:
Fatigue
Skin irritation or redness at the site of radiation
Hair loss (if treatment is near the scalp)
Nausea or difficulty swallowing (depending on the area treated)
Swelling or tenderness at the site of treatment
Most side effects are temporary and can be managed with medications or lifestyle adjustments.
