What should you know about flexitron brachytherapy?

A specialist places an applicator in or beside the area being treated. The Flexitron unit connects to that applicator and moves the radioactive source into position only when the treatment begins. Treatment planning determines the source position and dwell time so the intended area receives radiation while nearby tissue is considered. The applicator is removed after the session unless your team has explained a different schedule. This approach can be used in areas such as the cervix, womb, vagina, or prostate, depending on the diagnosis and treatment plan.

You may have an examination, imaging, or another planning assessment before treatment. The team will explain preparation, positioning, pain relief, and whether you need an anaesthetic. Temporary effects can include local soreness, irritation, pressure, or tiredness; the exact pattern depends on the treated body area and any external radiotherapy or medicines given with it.

Follow the instructions about eating, drinking, medicines, and arrival time. Tell the team about pregnancy, allergies, blood-thinning medicines, implants, or difficulty lying in the required position. Arrange transport if sedation or anaesthesia is planned. After treatment, use the hygiene and activity guidance supplied by your radiation team. A remote afterloader normally returns the source to its shielded housing when the session ends, so ask whether any special contact instructions apply to your particular treatment.

Keep a written list of symptoms and medicines for follow-up. Do not insert products or have sexual activity until your team says the treated tissue has had time to recover.

Contact your oncology team promptly for worsening pain, heavy or persistent bleeding, fever, foul-smelling discharge, difficulty passing urine, or inability to open your bowels. Seek urgent help for severe bleeding, collapse, sudden breathing difficulty, or severe pain that does not settle with the plan you were given. These symptoms need assessment; they do not by themselves identify the cause.

Ask which body area will be treated, how the applicator is placed, whether sedation is needed, how many visits are planned, which side effects should be expected, and whom to call outside clinic hours. Ask when you can return to work, exercise, sexual activity, and usual washing routines.
