The first and second inflatable ovoids are adapted for insertion within fornices of a patient. First and second retractors 130, 132 are adapted to be coupled to the ovoid assembly 110. The first retractor 130 is adapted to be positioned to retract the bladder of a patient during treatment. The second retractor 132 is adapted to be positioned to retract the rectum of a patient during treatment. The tandem 102 and the first and second inflatable ovoids 112, 114 are adapted to be coupled to a radioactive source to deliver an implant radiation dose suitable for cancer treatment at a cancerous cervical treatment site in a patient.
