External Beam Radiation FAQ

External beam radiation is the most common form of radiation therapy used to treat cancer.  High energy radiation beams are directed from outside of the body into the tumor using a linear accelerator.

Will I be radioactive after treatment?

No, you will not be radioactive. It is OK to be around other people.

Will the treatments hurt?

No, you will not feel anything during your radiation treatments; they are painless.

How long will the treatments take?

The first two treatments will take between 25 to 45 minutes. Remaining treatments will take about 15 minutes. If you are receiving IMRT (Intensity Modulated Radiation Therapy) treatments, the first two days, plan to be in the department for one hour. Subsequent daily treatments will take 30 minutes.

How many treatments will I have to take?

The total number of treatments will depend upon the type of cancer, location and stage. On average you will be treated once per day, five days a week, for two to eight weeks. Your doctor will discuss this with you in more detail.

Will my hair fall out?

The radiation treatments may cause hair loss, but only within the area being treated. Your doctor will discuss this and any other possible side effects with you.
