Cervical cancer radiotherapy treats the cervix and nearby pelvic areas using carefully planned radiation. It is often given with chemotherapy, and many treatment plans include both external beam radiotherapy and brachytherapy.
This combination can sound like a lot. Your team should explain the order of treatment and what each part is meant to do.
Common Indications for Cervical Cancer Radiotherapy
Your doctor may recommend it for:
- Cervical cancer that is too large for surgery.
- Cancer involving nearby tissues.
- Cancer found in pelvic lymph nodes.
- Treatment after surgery in higher-risk cases.
- Bleeding or pain control.
- Cancer that has returned in the pelvis.
What exactly does cervical radiotherapy treat?
It treats the cervix, uterus area, nearby tissues, and sometimes pelvic lymph nodes. Brachytherapy gives an extra focused dose close to the cervix.
How should I prepare?
You may need a planning scan and daily bladder or bowel instructions. For brachytherapy, you may need fasting, admission, anaesthesia, or pain control.
Do I need to stop taking medication?
Do not stop medication without advice. Tell the team if you take blood thinners, diabetes medicine, HIV treatment, herbal medicines, or chemotherapy.
What happens when I arrive?
For external treatment, radiographers position you on the couch and check your setup. For brachytherapy, the team prepares you for an internal procedure.
How is the treatment performed?
External beam treatment comes from a machine outside the body. Brachytherapy places applicators inside the vagina and cervix area so radiation can be delivered close to the tumour.
How long does treatment take?
External sessions are usually short but repeated over several weeks. Brachytherapy appointments are longer because they include preparation, imaging, treatment, and recovery.
Is there any discomfort?
External treatment is painless. Brachytherapy can cause pressure, cramps, or soreness, so pain relief or anaesthesia is often planned.
Are there risks?
Side effects may include tiredness, diarrhoea, bladder irritation, pelvic cramps, skin changes, vaginal soreness, early menopause, fertility loss, and sexual changes. Your team should discuss these before treatment.
Can I have this treatment if I am pregnant?
Pregnancy Precaution
Tell your doctor immediately if you are pregnant or think you might be. Cervical cancer treatment during pregnancy needs specialist discussion because radiotherapy can harm the baby.
Fertility, menopause, and sexual health
Pelvic radiotherapy can permanently affect fertility and may cause early menopause and vaginal narrowing or dryness. If future pregnancy matters to you, ask about fertility preservation before treatment starts; not every option is possible once treatment is under way. Your team can also advise about sexual health, vaginal dilators when appropriate, and contraception.
When should I contact the team urgently?
Contact the team for heavy vaginal or rectal bleeding, fever, severe pelvic pain, inability to pass urine, repeated vomiting, dehydration, or uncontrolled diarrhoea. Seek emergency care if bleeding is heavy or you feel faint.

Conclusion
Cervical cancer radiotherapy is usually a planned course, not a single appointment. Ask your team to write down the external treatment days, brachytherapy dates, and what symptoms should make you call urgently.
