How to do radiation therapy?

If you decide to have external beam radiation therapy, you will be scheduled for a treatment planning session called a simulation. At this time: 1 A radiation oncologist (a doctor who specializes in using radiation to treat cancer) and radiation therapist will figure out your treatment area. You may also hear the treatment area referred to as the treatment port or treatment field. These terms refer to the places in your body that will get radiation. You will be asked to lie very still while x-rays or scans are taken. 2 The radiation therapist will tattoo or draw small dots of colored ink on your skin to mark the treatment area. These dots will be needed throughout your course of radiation therapy. The radiation therapist will use them to make sure you are in exactly the same position for every treatment. The dots are about the size of a freckle. If the dots are tattooed, they will remain on your skin for the rest of your life. Ink markings will fade over time. Be careful not to remove them and tell the radiation therapist if they fade or lose color. 3 A body mold may be made of the part of the body that is being treated. This is a plastic or plaster form that keeps you from moving during treatment. It also helps make sure that you are in exactly the same position for each treatment

What is the span of time from your first radiation treatment to the last?

What is stereotactic radiation?

Stereotactic body radiation therapy is similar to stereotactic radiosurgery, but it is used for small, isolated tumors outside the brain and spinal cord, often in the liver or lung. It may be an option when you cannot have surgery due to age, health problems, or the location of the tumor.

How do proton beams work?

Protons are particles with a positive charge. Like photon beams, proton beams can also reach tumors deep in the body. However, proton beams do not scatter radiation on their path through the body and they stop once they reach the tumor. Doctors think that proton beams might reduce the amount of normal tissue that is exposed to radiation. Clinical trials are underway to compare radiation therapy using proton beams with that using photons beams. Some cancer centers are using proton beams in radiation therapy, but the high cost and size of the machines are limiting their use.

What type of radiation is used in x-rays?

Most radiation therapy machines use photon beams. Photons are also used in x-rays, but x-rays use lower doses. Photon beams can reach tumors deep in the body. As they travel through the body, photon beams scatter little bits of radiation along their path.

Why do people have side effects from radiation?

They usually happen because radiation therapy can injure healthy cells that are near the cancer cells it is destroying. Side effects depend on the part of your body being treated. It's important to keep in mind that they differ in degree from person to person.

How does a PET scan work?

During treatment, you will have repeated scans, such as CT, MRI, or PET scans. These scans are processed by computers to detect changes in the tumor’s size and location. The repeated imaging allows for your position or the radiation dose to be adjusted during treatment if needed.

What are the particles used in radiotherapy?

Most types of radiotherapy treatments use photons (such as x-rays), but tiny particles called electrons and protons can also be used. Photons and protons can treat cancers that are deep inside the body or those on or close to the skin (superficial cancers). Electrons are only used for superficial cancers.
