What is Intensity-Modulated Radiation Therapy (IMRT)?

  • A type of radiation treatment for cancer
  • Uses advanced imaging techniques to precisely shape and deliver radiation doses to a tumor or other area of the body.
  • This technique minimizes damage to the surrounding organs.

Why is Intensity Modulated Radiation Therapy (IMRT) Done? 

IMRT is a good option for treating tumors in sensitive areas where radiation exposure could affect sensitive organs.

IMRT is used to treat:

  • Prostate Cancer
  • Breast Cancer
  • Cervical Cancer
  • Lung Cancer
  • Colon Cancer
  • Stomach Cancer
  • Uterine Cancer

IMRT helps to reduce side effects and improve the effectiveness of treatment.

How to Prepare for Intensity-Modulated Radiation Therapy (IMRT)?

  • Your doctor will perform a CT scan to generate images of the tumor
  • You will be marked with small tattoos to help the machine accurately deliver energy beams
  • You may also receive certain accessories (mold or mask) to hold your body in position during treatment

What to Expect During Intensity-Modulated Radiation Therapy (IMRT)?

  • 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
  • The dosing schedule varies, and usually, you will receive treatment during short 30-minute sessions, over a few days to weeks, with treatment lasting up to several weeks

What are the Advantages of Intensity-Modulated Radiation Therapy?

1. Increased Precision: IMRT allows the radiation to be delivered with greater precision than conventional radiation, which allows for better targeting of the cancer cells while sparing healthy tissue. 

2. Reduced Side Effects: IMRT can help reduce side effects by more precisely targeting cancer cells and avoiding healthy tissue. 

3. Increased Dose: IMRT can deliver a higher dose of radiation than conventional radiation, which is beneficial in treating certain types of cancer. 

4. Reduced Treatment Time: IMRT can reduce the total treatment time, which is beneficial for patients who may have difficulty completing the full course of treatment.

5. Increased Comfort: IMRT allows for flexible treatment positions, which can be more comfortable for some patients.

What is the recovery time for IMRT? 

The recovery time for IMRT varies depending on the type and severity of the treatment. Generally, most people who have undergone IMRT can return to normal activities within a few days to a week after treatment. Your doctor can provide more specific information regarding your recovery time.

What is the Recovery Care for Intensity Modulated Radiation Therapy (IMRT)? 

  • During treatment and recovery, your body may require a lot of rest
  • Eat a healthy diet and stay hydrated to help your body heal
  • Wear loose-fitting and comfortable clothes
  • Use personal hygiene products that are free of harsh chemicals and perfumes
  • Avoid using heating pads or ice packs on skin that has been directly exposed to radiation
  • Apply sunscreen to the exposed skin to protect your skin from sun damage
  • Never miss follow-up visits to monitor for any potential side effects such as fatigue, skin changes, and nausea
