Brachytherapy treats cancer by placing radioactive sources directly into or next to the area requiring treatment. This enables clinicians to deliver a high dose with minimal impact on surrounding healthy tissues.
Brachytherapy has proven to be a highly successful treatment for cancers of the prostate, cervix, endometrium, breast, skin, bronchus, esophagus, and head and neck, as well as soft tissue sarcomas and several other types of cancer.
Brachytherapy primarily uses two different techniques:
With any radiotherapy technique, the goal is the same: to conform the dose to the size and shape of the target while limiting side effects by sparing the surrounding healthy anatomy. In brachytherapy, radiation falls off very rapidly from the target area easily accomplishing this objective.
The oldest form of radiotherapy, brachytherapy now uses the latest in computer and radioactive source technology. Image guided brachytherapy (IGBT) combines advanced imaging techniques with advanced brachytherapy procedures allowing doctors to treat patients quickly and precisely.
Active in the brachytherapy market since 1994, Varian produces a full range of brachytherapy products including afterloaders, applicators, and treatment planning software.
