An individual treatment plan is generated for your radiation treatment. This provides all the parameters that are loaded into the treatment machine, to make sure the machine is set to deliver the correct amount of radiation each day. It will also contain instructions on to how to position you each day during treatment. The Radiation Therapist will follow these instructions when positioning you. Images may be taken prior to treatment to check that you are in exactly the same position that was planned, by comparing the machine images to those of the planning scan.
In a center that has AlignRT, a red light will shine onto your skin. The Radiation Therapists will use this to position you each day, and so skin marks and tattoos will no longer be necessary. The AlignRT system will also monitor your position during treatment.
The procedure is used often for patients with left-breast cancer, plus some other conditions, to reduce the negative side-effects of radiation. To prepare, follow the advice of your physician, which is typically to practice holding your breath for up to 20-30 seconds at a time, usually 2-8 times per practice session. This is what happens during DIBH treatments, so if you are ready for it, it will be easier for you. Also, if you are ready for DIBH, it enables the technique to be carried out more quickly, so you spend less time on the treatment table. (Insert link to DIBH video)
Treatments typically take on average between 5 and 30 minutes. This depends on the complexity of the individual treatment plan. Most of the time in the treatment room will be spent making sure you are in the correct position for treatment. The beam on time is usually less than a minute each time. You will most likely have radiation delivered from multiple different machine angles.
The number of treatments will vary depending on your individual treatment plan. Radiation Therapy is delivered over a number of treatments. Each treatment is called a fraction. It is normal to have anything from 1 to 45 fractions depending on your type of cancer. Most people have treatment once a day, Monday-Friday with a break over the weekends.
Radiation Therapy only effects the area that is being treated. Therefore, if you are having your head treated, the hair in the area that is being treated on your head will fall out. If you are having your breast treated, you will not lose the hair on your head.
No, you are not radioactive after the treatment with External beam Radiation Therapy
