KnowraBrachytherapyLinked fromLinked fromThe 9 pages that link to Brachytherapy, each with the reason it gives.All 9Broader topic 2Related 3Narrower topic 1Compared with 3Radiation therapyBroader topic: Placing the source close to the target can concentrate dose in a small region.Radiation dosimetryRelated: Accurate dose calculations are essential because sources deliver steeply varying doses over short distances.Photodynamic therapyCompared with: It offers localized treatment for some sites but uses ionizing radiation instead of light-activated drugs.RadiumNarrower topic: Radium sources were early brachytherapy implants, later largely replaced by other radionuclides.Boron neutron capture therapyCompared with: Both localize radiation, but brachytherapy uses implanted sources rather than boron-loaded cells.Group 9 elementRelated: Iridium-192 is a widely used source for temporary brachytherapy implants.Organs at RiskCompared with: Source placement changes which nearby organs receive substantial radiation.Radioactive sourceBroader topic: Small sources deliver radiation directly to tumors while limiting exposure to surrounding tissue.Caesium-137Related: Caesium-137 has served in sealed sources for treating cancers, especially gynecological tumors.
