Radiation therapy is a highly effective treatment for various cancers, helping millions of patients worldwide. However, many patients worry about whether radiation therapy makes them radioactive. This concern is understandable, given the nature of radiation, but the reality is much more reassuring. In this blog, Dr. Vineeta Goel, senior director in radiation oncology at Fortis Hospital, Delhi, explains how radiation therapy works and whether it poses any risks to those around you.
Understanding Radiation Therapy
Radiation therapy uses high-energy rays or particles to destroy cancer cells. It is one of the most common treatments for cancer, often used alone or in combination with surgery and chemotherapy. There are two primary types of radiation therapy:
- External Beam Radiation Therapy (EBRT): This is the most commonly used type, where a machine directs radiation at the affected area from outside the body.
- Internal Radiation Therapy (Brachytherapy): This involves placing a radioactive source inside or near the tumor.
Does Radiation Therapy Make You Radioactive?
The answer depends on the type of radiation therapy you receive:
- External Beam Radiation Therapy (EBRT): No, EBRT does not make you radioactive. The radiation is delivered externally and does not remain in the body. Once your treatment session ends, you can safely interact with family and friends without posing any risk to them.
- Internal Radiation Therapy (Brachytherapy): This type of therapy may involve temporary or permanent radioactive implants. If temporary, the radiation source is removed after treatment, and there is no residual radioactivity. If permanent, the radiation levels decrease over time, and doctors provide guidelines to ensure safety for those around you.
Are There Any Safety Precautions?
For patients undergoing EBRT, no special precautions are necessary. However, for those receiving brachytherapy, some temporary safety measures may be required, such as:
- Limiting close contact with young children and pregnant women for a specific period.
- Following personalized safety instructions from the radiation oncologist.
Radiation Therapy: Myths vs. Facts
There are many misconceptions about radiation therapy. Let’s address some common ones:
- Myth: Patients become radioactive after any type of radiation therapy.
Fact: Only certain types of internal radiation therapy require temporary precautions.
- Myth: Radiation therapy is always dangerous for people around the patient.
Fact: External beam radiation therapy does not make you a radiation risk to others.
- Myth: Radiation therapy causes severe long-term harm.
Fact: Modern radiation techniques are precise, minimizing damage to healthy tissues and reducing side effects.
Consult an Expert for Personalized Guidance
If you are considering radiation therapy, it is essential to consult an experienced radiation oncologist who can guide you based on your specific diagnosis and treatment plan. Dr. Vineeta Goel, one of the best radiation oncologists in Delhi, has extensive experience in advanced radiation therapies and ensures patients receive the safest and most effective treatment.
Final Thoughts
Radiation therapy is a crucial tool in cancer treatment, and concerns about becoming radioactive should not be a reason to avoid it. Understanding the type of radiation therapy you receive and following medical guidance ensures both effective treatment and safety for those around you. If you have any concerns, always discuss them with your oncologist for accurate information and peace of mind.
