Which of the following treatments is the latest for the treatment of all types of cancer?

Question

Accepted Answer

Intensity-modulated radiation therapy (I.M.R.T). Intensity-Modulated Radiation Therapy (IMRT) is the latest for the treatment of all types of cancer. It is a type of conformal radiotherapy. Conformal radiotherapy shapes the radiation beams to closely fit the area of cancer.The IMRT has a device called a multileaf collimator. The multileaf collimator is made up of thin leaves of lead which can move independently. They can form shapes that fit precisely around the treatment area. The lead leaves can move while the machine moves around the patient. This shapes the beam of radiation to the tumour. This means that the tumour receives a very high dose and normal healthy cells nearby receive a much lower dose. Each radiotherapy beam is divided into many small beamlets that can vary the intensity of radiation. This allows different doses of radiation to be given across the tumour. IMRT can be very helpful in head - neck -prostate cancer.
