Radiation therapy is a type of treatment that uses high doses of radiation to kill cancer cells and shrink tumors. This treatment can be delivered externally via a machine or internally through radioactive material placed inside the body. Despite its common use in oncology, several misconceptions about radiation use in therapy persist. Here is information on three common misconceptions about radiation therapy:
Myth 1: Radiation Therapy Causes Full-body Hair Loss
A prevalent myth is that undergoing radiation therapy will inevitably lead to the complete loss of hair all over the body. This is not accurate, as the effects of radiation are localized to the specific area being treated. Hair loss, or alopecia, only occurs if hair follicles are within the direct path of the radiation beam.
Radiation therapy is a primary treatment modality for many types of cancer, utilizing high-energy waves to target and destroy abnormal cells. This treatment works by damaging the DNA within cancer cells, which stops them from dividing or causes them to die. While the goal is to eliminate or shrink tumors, the technology spares as much healthy surrounding tissue as possible.
How Does This Therapy Impact Hair Loss?
Radiation therapy is precise, so hair follicles will be affected only in the area being treated. A person receiving radiation to the brain for a tumor may lose hair on their head, but a person receiving treatment for prostate cancer will not. The hair loss is limited to the treatment field, and it may be temporary or permanent depending on the radiation dose.
What Are the Side Effects?
Side effects from radiation therapy also depend on the part of the body receiving treatment. The high-energy beams used are focused on a precise target area, so effects are typically confined to that region. A patient receiving radiation to the abdomen may experience digestive issues, while a patient treated for breast cancer might notice skin changes in the chest area. Some other common side effects may include:
- Headaches
- Fatigue
- Diarrhea
- Appetite Reduction
Myth 2: This Therapy Always Causes Vomiting
Another common concern is that radiation therapy will consistently cause severe nausea and vomiting. While this can be a side effect, it is not a universal experience for every patient, and it is often manageable. The likelihood of experiencing nausea is related to the area of the body being treated.
Radiation directed at the abdomen, small intestine, or certain parts of the brain is more likely to cause these symptoms. The dose of radiation administered per session also plays a role, as higher doses can increase the chance of nausea. Medical teams often provide medication to help manage these side effects effectively.
Myth 3: This Therapy Is Painful
Many people believe the process of receiving radiation is painful. The experience can be compared to getting an X-ray; the patient does not feel the radiation as it enters the body. For this therapy, patients lie still on a table while a machine directs the radiation to the targeted area. While the treatment itself is not painful, some side effects that develop over time, such as skin irritation or mouth sores, can cause discomfort. These potential side effects are closely monitored by the healthcare team, who can provide strategies and treatments to alleviate them.
Learn More About Radiation Therapy
Misinformation can create unnecessary confusion surrounding cancer treatment. By addressing these common myths, patients and their families can develop a clearer understanding of what to expect from this therapy. To learn more about radiation, contact an oncology medical team to discuss your questions. They can provide personalized information based on an individual’s specific diagnosis and treatment plan.
