Pelvic Radiation Disease in the UK

Many of the 22,000 people treated each year with pelvic radiotherapy have debilitating side effects which reduce their quality of life, sometimes for many years or decades.

The Pelvic Radiation Disease Association (PRDA) estimates that at least 100,000 people in the UK experience ongoing problems due to the side effects of radiotherapy to the pelvic region.

In October 2022 the Pelvic Radiation Disease Association published the Pelvic Radiation Disease Best Practice Pathway to support healthcare professionals address the holistic needs of people affected by long-term side effects of pelvic radiotherapy.

The document will help to develop high quality, multi-disciplinary, person-centred pathways of care.

How PRDA supports health professionals:

1. A small range of free patient leaflets and posters are available for hospital clinics and GP surgeries.

2. We aim to keep professionals updated with clinical guidance and information on Pelvic Radiation Disease.

3. We can connect you with professionals in your area (mainly gastroenterologists) who are willing to accept referrals for suspected PRD – email

4. We can forward your requests for advice on any aspect of PRD to our Medical Advisory Panel members – email

5. We can connect you with patient speakers or representatives for educational events, patient forums and research study groups.

6. Our Research News page highlights key studies in the field of PRD.

7. Our Real life stories page and our Online Community provide insight into the lived experience of people affected by PRD. We have provided an example of a person experiencing PRD and how they have had to persevere to find support.

8. We are developing a collaborative network of professionals working with people affected by PRD. Please get in touch if you would like to find out more – email

PRDA’s definition of Pelvic Radiation Disease

Pelvic Radiation Disease (PRD) is defined as one or more ongoing symptoms of variable complexity that may affect people who have previously had radiotherapy to the pelvic region to treat their cancer. This includes pelvic radiotherapy for cancers of the colon, rectum, anus, prostate, testes, bladder, cervix and womb, but also total body radiotherapy and radiotherapy in the pelvic area for other primary and secondary cancers.

Pelvic Radiation Disease can affect one or more of:

Bladder Bone
Bowel Nerves
Sexual Organs Blood supply
Stomach and digestion Lymphatic system
Skin Mental health

Symptoms arise as a result of damage to internal organs or skin. Symptoms often settle in the few weeks after radiotherapy finishes but Pelvic Radiation Disease can be defined as symptoms starting or continuing 3 months or more after the end of radiotherapy. Sometimes they start many years or decades after radiotherapy.

The following Pelvic Radiation Disease symptoms range from mild to severe, and some are more common than others, but all tend to be under-recognised:

  • bowel and stomach difficulties* (almost any bowel or stomach symptom can be caused by radiotherapy but the most common symptoms are accidents, leakage or an inability to control the bowel or hang on, diarrhoea, need to rush to the toilet, bleeding from the bowel, poor appetite and malnutrition)
  • bladder difficulties (such as leakage or lack of control, need to rush to pass urine, bleeding)
  • sexual difficulties (such as painful intercourse for women or achieving and maintaining a satisfactory erection and/ or problems with ejaculation for men)
  • pain
  • fatigue
  • swelling (e.g. lymphoedema)
  • poor mobility
  • blood circulation disorders
  • anaemia
  • sore skin
  • nerve damage
  • bone fractures
  • hormonal changes (such as hot flushes)
  • infertility
  • sleep disturbance
  • memory problems
  • psychological difficulties.

*A full list of gastrointestinal symptoms can be found in ‘The Practical Management of the Gastrointestinal Symptoms of Pelvic Radiation Disease‘.

All or any of these symptoms can have profound effect on a person’s ability to live a normal life. However, with correct diagnosis, treatment and care by health professionals with expertise in PRD, and with support to self-manage problems, significant improvement to quality of life can be made.

Other words that are sometimes used to describe symptoms of PRD include:
Radiation enteritis, Radiation proctitis, Radiation colitis, Radiation enteropathy, Radiation cystitis, Radiation cystopathy, Radiation-induced lumbar plexopathy and Pelvic insufficiency fractures.

PRDA believes that the overarching term ‘Pelvic Radiation Disease’ should be used, as it covers the fact that often several organs, as well as mental health, are affected. The term Pelvic Radiation Disease therefore encourages a multi-professional approach to patient care to be taken.

The Pelvic Radiation Disease Association aims to support all people affected by, or at risk of, side effects due to pelvic radiotherapy, at any stage of cancer treatment, and however long ago cancer treatment was given.
