How to Prepare for Radiation Therapy
What to Expect from the Treatment Process
Patients referred to Coastal Radiation Oncology often wonder what radiation therapy involves. They are unsure about what to expect from the treatment sessions, the schedule of treatments or what types of side effects they might experience.
Each patient we care for undergoes a treatment plan that is unique to them and their specific diagnosis. Below is a list of steps that our patients can expect and prepare for prior to, during and following radiation therapy treatment:
Prior To Treatment
If we do need you to request the records, please be aware that it can take up to 15 days for medical offices to supply you with copies of your records, so filing a timely request is important. It is important to have this information readily available so that the start of your treatment is not delayed.
When your first arrive at our office, our receptionists will guide you in completing the necessary paperwork, answering your questions regarding insurance, and getting you in to see the physician in a timely manner.
The physician will spend time with you in order to fully explain the benefits and potential side effects of the treatment. He or she will most likely speak with your referring physician to ensure the continuity of your treatment, especially if you will be receiving chemotherapy at some point in your treatment. During this consultation appointment, you will have the opportunity to begin scheduling your radiation therapy.
Treatment and Planning Simulation
At the time of the scan, tiny tattoos or marks will likely be placed on your skin to allow precise replication of the CT position when actual treatments are given. These marks are the size of a tiny freckle, and are generally quite hard to detect unless, like our radiation therapists, you have placed these marks and are looking for them.
Certain tumor locations require a mesh facial mask or other immobilization devices to be fitted to ensure perfect immobilization so that we treat tumors near vital structures (such as the spinal cord or salivary glands) with a better chance of avoiding damage to the normal structures nearby. For some tumors of the head and neck region, a dentist may have made plastic molds for your teeth; these molds should be brought and put on for the CT scan and left in our office so they can be used at subsequent appointments.
After the CT scan is completed, the information is fed into a computer and a dosimetrist or physicist works with the physician to create a plan which delivers the most radiation to the tumor, and the least to surrounding tissues. This planning requires 5-7 working days. You will be given a tentative start date for your radiation treatment at the time of the CT scan. Mesh mask or other immobilization devices should be left in our office so they can be used at subsequent appointments.
When the treatment plan is completed and approved by the physician, you will return and be placed on the actual treatment table (linear accelerator). Tiny pen marks or tattoos ensure that you will be in perfect alignment every day for your therapy. If a mesh mask or other immobilization device was made, it will be put on as well.
At this time x-ray exposures will be taken to make sure the actual treatment position is exactly the same as the CT position, so the radiation goes exactly to the tumor. These exposures will be reviewed by the physician, and if approved the treatments will begin, usually the next day.
In a typical radiation treatment regime, you should expect to be treated daily, Monday through Friday for approximately 5-8 weeks, except for Accelerated Partial Breast Irradiation, which requires just 5 consecutive days, and other HDR procedures, which are usually done once per week for a specified amount of time. You will usually be in and out of the office in about half an hour for most external radiation treatments, barring any unforeseen scheduling problems. The actual treatment only takes a minute or two, but we need to make sure you are in the exact same position each day.
For some complicated cases, more advanced radiation treatments such as IMRT, IGRT, or SRS will be used, and these may take 20-30 minutes to complete.
As you continue through your therapy, the physician and physicist will be monitoring your treatment dose and will be made aware of any side effects that you might experience. Normally you will leave right after treatments, but at least once a week, you will be seen by a physician to review your treatments, answer questions, check for side effects and conduct an exam. The doctor can give advice on skin care, prescribe or renew medications and try to relieve concerns you may have. However, if you have problems at other times during the week, notify any office personnel, and you can be seen by the physician then as well.
You will then come back for additional follow-up visits as needed.
