Introduction: Brachytherapy is a treatment in which sealed radioactive
sources are used to deliver high doses of radiation at close distance to the tumor with
rapid dose fall-off in the surrounding normal tissue resulting in high therapeutic ratio in
oncological disease management. It is effective in palliative treatment for patients with
symptoms of hemoptysis and dysnea resulting from endobronchial obstruction.
Conclusion: In spite of the rapid development of external beam radiation therapy
brachytherapy continues to remain an important mode of therapy and is often a default
treatment when external beam radiation option is limited.
