A form of radiation therapy to treat cancer
A machine rotates around your body to deliver a radiation dose that kill the cancer cells
This technique minimizes the damage to the surrounding organs
VMAT is convenient for patients who cannot lie down for extended periods.
How To Prepare for Volumetric Modulated Arc Therapy (VMAT)?
(Radiation Technique)
· Your doctor will generate 3D images of your body to identify the tumor and determine the radiation dose to destroy cancer.
· You may receive temporary or permanent markings on your body that locates the tumor
· You may also receive certain accessories (mold or mask) to hold your body in position during treatment
What to Expect During Volumetric Modulated Arc Therapy (VMAT)?
(Radiation Technique)
· Your doctor will position you and operate the machine from a separate room
· The machine slowly rotates around you, delivering radiation beams to target your tumor
· Each session usually requires one or two rotations to deliver the complete radiation dose
How long does volumetric modulated arc therapy (VMAT) treatment take?
(Radiation Technique)
Treatment sessions take about 20 minutes. It takes approximately two minutes for the machine to deliver the radiation.
Depending on the cause, you may need daily VMAT treatment sessions for several weeks.
What are the benefits of volumetric modulated arc therapy (VMAT)?
(Radiation Technique)
· Minimal damage to the surrounding tissues
· Each session lasts about two minutes or sometimes less
· Faster treatments improve the accuracy of radiation delivery
· Very accurate
· Shortens the treatment time
· Uses a lower overall dose of radiation
Are there any side effects for volumetric modulated arc therapy?
(Radiation Technique)
Since VMAT spares healthy tissue from harmful radiation, there are fewer side effects, like,
· Weakness
· Nausea
· Vomiting
· Diarrhea
· Hair Loss
· Skin irritation
What Types of Cancers Does VMAT Treat?
(Radiation Technique)
VMAT is a form of radiation therapy that treats certain cancers like,
· Skin Cancers
· Head and Neck Cancers
· Brain Cancers
· Gastrointestinal Cancers
· Lung Cancers
Only your doctor can suggest whether you need to undergo VMAT or not.
