Radiotherapy Myths Busted: What Every Cancer Patient Should Know
Cancer is a word that brings with it many questions, fears, and unfortunately, myths.
Radiotherapy is the most misunderstood parts of cancer treatment. Despite being a powerful
and effective tool in fighting cancer, radiotherapy is often associated with misconceptions that
create unnecessary anxiety for patients and their families.
In this article, let us uncover the truth behind some of the most common myths about
radiotherapy, so patients can approach treatment with clarity and confidence.
Myth 1: Radiotherapy burns the skin like fire.
Fact:
Many patients worry that radiation will severely burn their skin. While it is true that some skin
changes like redness or dryness may occur (like a mild sunburn), modern radiotherapy
techniques like IMRT, VMAT, and IGRT are highly precise. They minimize exposure to healthy
tissue and significantly reduce the chances of skin damage. Most patients tolerate treatment
very well with only minor and manageable side effects.
Myth 2: Once you receive radiotherapy, you cannot get it again.
Fact:
This is not always true. Re-irradiation is possible, especially with advanced techniques and
careful planning. The decision depends on several factors including the type of cancer, the area
previously treated, the radiation dose received, and how much time has passed. Your radiation
oncologist will guide you on whether re-treatment is safe and beneficial in your case.
Myth 3: Radiation causes cancer to spread.
Fact:
This is a dangerous and false myth. Radiotherapy does not cause cancer to spread. In fact, it
is used to kill cancer cells, shrink tumors, and prevent recurrence or spread. Sometimes, if
a patient has already advanced cancer, it may appear to spread around the time of treatment —
but this is due to the natural course of the disease, not the radiation itself.
Myth 4: Radiotherapy is painful.
Fact:
Radiotherapy is a painless procedure. It is very similar to getting an X-ray. You will lie still on a
treatment table while a machine delivers targeted radiation beams to the cancer site. The actual
treatment takes just a few minutes, and you will not feel the radiation at all. Some patients
may experience fatigue or local side effects over time, but the session itself does not hurt.
Myth 5: Side effects of radiotherapy are worse than cancer itself.
Fact:
Every treatment has potential side effects, and radiation is no different. However, with proper
planning, advanced techniques, and supportive care, most side effects are manageable and
temporary. Your oncologist will work closely with you to reduce discomfort and protect your
quality of life during and after treatment.
Final Thoughts:
Radiotherapy plays a life-saving role in cancer treatment—whether used alone or in
combination with surgery or chemotherapy. Dispelling myths and understanding the truth is
essential for making informed decisions and reducing fear.
If you or your loved one is about to undergo radiotherapy, do not hesitate to ask your oncologist
questions. Knowledge reduces fear, and trust in your treatment can empower healing.
