Breakthrough in External Beam Cancer Treatment

External Beam Radiation is the most widely used technique to treat prostate cancer today. It works by administering radiation (a stream of energy carried by waves or particles) to the tumor site. The radiation beam comes from a machine called a linear accelerator (think of it like a controlled laser gun.) The radiation beam is then directed to destroy the malignant cancer cells. Of course, some normal cells are going to be caught in the crossfire, but the radiation oncologist’s goal is to keep it to a minimum and just terminate the malignant areas of the prostate.

How IMRT Works

 Accuracy is everything when it comes to external beam radiation. A new breakthrough technique called Intensity-Modulation Radiation Therapy or (IMRT) is at the forefront of this technology; delivering a certain and efficient method of radiation therapy. Here is how it works.

IMRT allows doctors to customize the radiation dose by modulating or varying, the amount of radiation dose given to different parts of the treatment area. This modulation is done in highly accurate, three-dimensional detail, according to the shape, size, and location of the tumor. This allows the radiation oncologist to spare the amount of normal tissue cells damaged in the process and target the malignant areas more accurately.

The Process

The IMRT process generally consist of several steps, including consultation, positioning, imaging, treatment planning, plan verification, and  treatment delivery. A dedicated team of medical professionals will guide you and work with you every step of the way.

IMRT offers new hope for cancer patients. However, it may not be the most appropriate treatment option for your situation. Your doctor will work with you to determine which treatment is best for you.
