Vaginal Dilators After Pelvic Radiotherapy: Three Questions for Your Team

After cancer treatment, another set of instructions can feel difficult to take home, especially when it concerns a part of your body you are anxious about touching. Bring those concerns into the appointment before agreeing on a routine.

1. What is the aim for me?

Sussex’s patient guidance describes using dilators to reduce problems associated with vaginal scarring and support comfortable internal examinations and sex. Ask which concerns apply to your treatment and how the team will review your progress.¹

The research needs careful interpretation. A 2021 randomized trial in women treated for cervical cancer reported less worsening on a vaginal-narrowing scale among dilator users. Vaginal volume nevertheless decreased similarly across treatment groups. The authors described limited statistical power. These findings do not establish that dilators prevent every vaginal change after radiotherapy.²

If sexual activity is something you do not want to discuss today, say so. You can still ask about examinations and the practical details of your care.

2. When and how should I start?

Get your team’s start date, starting size, lubricant advice and schedule in writing. Sussex recommends waiting after treatment and allowing longer if soreness persists. It advises lubricating the device and inserting gently only as far as comfortable, without force.¹

Ask for a demonstration using the device outside your body. Take the written plan home so you can check the instructions without relying on what you remember from a busy visit.

3. What should make me call?

Sussex notes that light spotting can occur, but advises seeking clinical advice for heavy vaginal bleeding or pain. Ask whom to contact, including outside office hours. Check the dilator for damage before use and request a replacement if needed.¹

Write down the concern you want help with before calling. You can tell the nurse that the routine feels difficult, uncomfortable or upsetting and ask to discuss the plan again.
