Intensity Modulated Radiation therapy cures cancer by radiation therapy by providing the dose to the tumor without affecting the tissues that surround that tumor. It has proven to be a great technique for the people who are having cancer in or near their vital organs. This treatment is beneficial for those tumors which are difficult to reach and are in a remote area of the body. It also involves an advantage of that it does not affect the normal tissue and hence if re-radiation therapy of the affected tumor is required, it can be easily done. It can cure any kind of tumor regardless of size, structure and location and shape. In this process, numerous small radiations of several intensities are directed to pass through the affected area. The first step involves the immobilization of the patient, then simulation through the radiator.
The CT scan is performed on the affected area, at regular intervals. Then the data is collected and recorded. This ensures the correctness and accuracy of the treatment so that there is no scope of any mistake in the treatment.
The average cost of Intensity Modulated Radiation Therapy (IMRT) ranges from USD 7500 in India compared to USD 8500 in Germany. The price of the Intensity Modulated Radiation therapy in the United States of America starts from USD 12,834.
Hence the treatment is done by linear accelerators with supreme accuracy to treat the tumor, which is done in various countries, but the doctor and hospital shall be chosen wisely.
Intensity-modulated radiotherapy (IMRT) is a type of conformal radiotherapy, a technology that enables the radiation oncologist to precisely target the tissues with cancer cells. . In this type of radiation therapy for cancer, the radiation beams closely take up the shape of the area that is being targeted.
IMRT is delivered through the standard radiotherapy machine, which is also known as the linear accelerator (LINAC). This machine has a device called multileaf collimator, which possesses lead leaves that can move independently to form a shape that best fits the target area.
Because the radiation beams can take up the shape of the target area, high dosage of radiation can be delivered to kill the cancer cells while minimizing exposure to the non-cancerous cells and tissues. IMRT proves to be highly effective in the case of head and neck cancer among other types of cancer.IMRT for prostate cancer is now available across all major hospitals around the world.
The efficiency of IMRT has already been tested for multiple cancers, including breast cancer. Latest advancements improving the efficacy of radiotherapy, however, continue to take place in the field of healthcare. This radiation treatment for cancer is already being used as a standard treatment for some cancer types.
Typically, the following steps are performed during the IMRT session:
A typical IMRT session lasts for about 15 to 30 minutes.
IMRTradiation therapy for cancer is a painless procedure. The patient does not feel anything during the radiotherapy session. However, there could be some level of discomfort due to posture or the use of masks and moulds. After this radiation treatment for cancer, the patient is made to lie on the table for a few minutes after the treatment to relax.
A few patients may experience increased frequency of urination or a sudden urge to urinate. Patients are advised to drink at least six to eight glasses of water every day to recover quickly from the session. Additionally, they should try to avoid excess consumption of spicy foods, caffeine, and alcohol during the recovery phase.
Recovery Process post-Intensity-modulated radiotherapy (IMRT)
Some patients may feel excessive tiredness and fatigue during the course of radiation treatment. Such patients should plan their daily activities and take several short naps during the day to manage their energy levels. Additionally, they are advised to take high protein and high-calorie foods during and after the treatment.
Patients should use a non-scented soap to clean the area that has been exposed to radiation. Additionally, they should keep their skin moisturized.
