Brachytherapy is actually over 100 years old. I had a newer form of Brachytherapy, your type is too, called, HIgh Dose Rate Intraopertive Radiation Therapy (HDR-IORT), twice, a year apart, to the cervical neck, which is done during surgery in a shielded OR, after maximum resection, which uses the same remoteafterloader device, some look like R2-D2, with iridium 192 radiation source, as HDR-Brachytherapy does, but differed in several ways. Mine was done with one high dose directly to the exposed tumor bed, as a radiation boost, which was followed by external beam radiation with IMRT, several weeks later. HDR-Brachtherapy can also be done as monthotherapy, or in addition too surgery and or with EBRT, and is usually done in several sessions in one or two days.

Good luck with everything, and look forward to your posts. Several other members here had brachytherapy also.
