What to Expect When Having Radiation Therapy
Your radiation therapy team
A highly trained medical team will work together to provide you with the best possible care. This team may include these members:
Radiation oncologist. This doctor specializes in giving radiation therapy to treat cancer. A radiation oncologist oversees radiation therapy treatments. He or she works closely with other team members to develop the treatment plan.
Radiation oncology nurse. This nurse specializes in caring for patients receiving radiation therapy. A radiation oncology nurse plays many roles, including:
Answering questions about treatments
Monitoring your health during treatment
Helping you manage potential side effects
Medical radiation physicist. This professional has expertise in radiation equipment. He or she helps design treatment plans.
Dosimetrist. This professional helps the radiation oncologist calculate the right dose of radiation.
Radiation therapist or radiation therapy technologist. This professional operates the treatment machines and gives patients their scheduled treatments.
Other health care professionals. Others will help care for additional physical, emotional, and social needs during treatment. These professionals include:
Nutritionists or dietitians
Meeting with your radiation oncologist. The doctor will review your medical records, perform a physical exam, and recommend tests. Additionally, you will learn the potential risks and benefits of radiation therapy. This is also your opportunity to ask questions.
Giving permission for radiation therapy. If you choose to receive radiation therapy, your team will ask you to sign an informed consent form. Signing the document means:
Your team gave you information about your treatment options.
You choose to have radiation therapy.
You give permission for caregivers to deliver the treatment.
You understand the treatment is not guaranteed to give the intended results.
Simulating and planning treatment. The first radiation therapy session is a simulation. This is a practice run without giving radiation therapy. Your team will use imaging scans identify the tumor location. These may include:
Depending on the area being treated, you may receive a small mark on your skin. This will help your team aim the radiation beam at the tumor.
You may also be fitted for an immobilization device, which could include:
These help you stay in the same position throughout each treatment.
For radiation therapy to the head or neck, you may receive a thermoplastic mask. This is a mesh mask that is molded to your face and secured to the table. It gently holds your head in place.
Your radiation oncology team cares about your comfort. Talk with the team to find a comfortable and reproducible position for treatment. And tell your team if you experience anxiety lying still in an immobilization device. Your doctor can prescribe medication to help you relax for the treatment planning scan and the treatments.
After the simulation, your team will review your information and design a treatment plan. Sophisticated computer software helps the team develop the plan.
External-beam radiation therapy. External-beam radiation therapy delivers radiation from a machine outside the body. Each session is quick and painless, lasting about 15 minutes. Typically, patients have treatment sessions 5 times per week (Monday through Friday). This schedule continues for 3 to 9 weeks.
This type of radiation therapy targets only the tumor. However, it will affect some healthy tissue surrounding the tumor. The 2-day pause in treatment each week allows your body to repair this damage.
Internal radiation therapy, also called brachytherapy. This includes both temporary and permanent placement of radioactive sources in the tumor site. Typically, you receive repeated treatments across a number of days and weeks. These treatments may require a brief hospital stay. Also, you may need anesthesia to block the awareness of pain while the radioactive sources are placed in the body.
Most patients feel little to no discomfort during treatment. However, some may experience weakness or nausea from the anesthesia.
You will need to take precautions to protect others from radiation exposure. The need for such precautions ends when:
The permanent implant loses it radioactivity
The temporary implant is removed
Weekly reports. Your radiation oncologist will assess how well treatment is working, typically at least once a week. If needed, he or she may adjust your treatment plan.
Personal care. Many people experience the following during treatment:
Sensitive skin at the site of radiation exposure
Consider these ways to care for yourself:
Plan for extra rest.
Eat a healthy diet.
Seek emotional support.
Treat skin with lotions approved by your health care team.
Minimize exposure to the sun.
Once treatment ends, you will have follow-up appointments with the radiation oncologist. This involves:
Monitoring your recovery
Watching for treatment side effects, which may not happen immediately
As your body heals, you will need fewer follow-up visits.
Ask your doctor for a written record of your radiation treatment. This is a helpful resource as you manage your long-term health care.
