Intensity Modulated Radiation Therapy (IMRT), a highly sophisticated type of radiation therapy, is becoming increasingly common in the treatment of cancer of the prostate, spine, breast, kidney, pancreas, liver, larynx, tongue and sinuses. Despite its effectiveness, IMRT poses a risk of side effects in some patients.
Function
IMRT uses computer-controlled small beams of light delivered from many angles to destroy cancer cells. Doctors tailor the configuration of the beams for the precise shape and size of an individual tumor, reports RadiologyInfo.org.
Benefits
Though its side effects are similar to traditional radiation therapy, IMRT's effects are usually less severe because the process allows for a greater amount of focus and concentration upon the tumor. This spares regular cells from the damaging effects of the radiation, according to the International Radiosurgery Association.
Types of Common Side Effects
IMRT frequently causes skin redness and irritation followed by dryness and peeling as treatment progresses. Other common side effects include fatigue, hair loss in the affected area, nausea and mouth inflammation, reports the Mayo Clinic.
Time Frame
Some side effects from IMRT begin within hours of the first treatment, while others take longer to develop. Some side effects, such as fatigue, linger for up to a year after the treatment ends.
Risks
There is a slight increased risk of developing cancer later in life after receiving radiation treatment, according to the Mayo Clinic.
