LDR Brachytherapy is a powerful form of internally delivered radiation therapy that destroys many types of cancers including cervical, esophageal, head and neck and lung, but it is most often used to treat prostate cancer. LDR Brachytherapy can be used as a standalone treatment or after a tumor has been surgically removed to eliminate any remaining cancerous cells.
LDR Brachytherapy targets tumors with radiation delivered through a catheter. Since the radiation does not pass through healthy tissue to treat the tumor, it is extremely precise and enables your Radiation Oncologist to target the radiation directly at the tumor site with less risk of damage to surrounding healthy tissue.
With Low Dose Rate Brachytherapy treatments, small seeds, each the size of a rice grain, are surgically implanted in the tumor site through a tiny applicator to slowly deliver radiation. Seeds are most commonly used for prostate cancer and for some forms of cervical, esophageal, head and neck and lung cancers. Patients may need to take some precautions after their treatment is over, particularly if they are around children or pregnant women. Over time, the pellets become non-radioactive.
LDR Brachytherapy is relatively pain-free, with patients reporting only mild levels of discomfort during the insertion and removal of the catheters and devices used to deliver the radiation source to the tumor site.
