Visualisation is also called guided imagery and uses the power of your imagination to help you relax or relieve symptoms.


  • Visualisation can help to relieve stress.
  • It can help control some of the symptoms caused by cancer or cancer treatments.
  • It can lift your mood which might help you to feel more balanced.

What visualisation involves

A trained therapist can help you learn how to practice visualisation.

You create images in your mind that can help you to relax, feel less anxious, sleep better, and reduce pain. You use all of your senses – sight, touch, hearing, smell, and taste. For example, you may want to think of a place or activity that made you happy in the past. 

While you are learning the technique, your therapist talks you through the sort of images that it may be helpful to picture. They may ask you to imagine a peaceful place where you’d like to be. Or they might teach you to imagine yourself feeling well and strong.

Many people find that they feel better after they imagine feeling stronger. Some people like to picture their body fighting off the cancer cells.

A therapist may be able to teach you the best visualisation techniques for the times when you feel most stressed. They can show you short visualisation exercises or deeper relaxation techniques.

You can practice visualisation without a therapist, using a music file, CD or app. You can buy these online or from some book shops, and from some cancer support groups or centres. Ask your nurse if they can recommend any. Or you could contact one of the complementary therapy organisations.

If you have to stay in bed or can't leave your home, imagery or visualisation techniques may help. You may feel less closed in if you have been indoors for a long time.

Possible side effects

Visualisation and guided imagery are generally safe, especially under the guidance of a trained health professional.

It is best to use them alongside your conventional cancer treatment.

There are no reports of side effects.

Research into visualisation in cancer care

Relaxation and imagery are two of the most popular types of complementary therapy that people with cancer use.

Research has looked into visualisation to help control symptoms and treatment side effects in people with cancer. It is difficult to do this type of research and the results are sometimes not clear. We need more research to see how guided imagery and visualisation can help people with cancer.

In 2010 the PERI study reported its results. It looked at visualisation and guided imagery for patients with bowel cancer. The study included 151 patients and found that relaxation and guided imagery did not significantly change people’s mood or quality of life.

An earlier review of 6 studies in 2005 suggested that guided imagery may be helpful in managing stress, anxiety, and depression for people with cancer. Further research in this area is needed.  

A very small pilot study in 2016 looked at using guided imagery and relaxation to see if it could help with pain, fatigue and sleep disturbances for people having cancer treatment. The guided imagery and relaxation seemed to improve sleep and fatigue levels but it didn't appear to help pain in the participants.    

In 2012 an American study looked at guided imagery for patients having radiotherapy for breast cancer. The study found that patients who had guided imagery had lower breathing and pulse rates and lower blood pressure. They also had a slightly higher skin temperature which showed that they felt more relaxed.

Overall, more than 8 out of 10 participants in the study described the guided imagery sessions as helpful. All of the people who took part said that they would recommend guided imagery to others.

A review of studies for women with breast cancer who had hot flushes was carried out in 2010. It looked at medicine treatments and non medicine treatments that aimed to reduce hot flushes. The non medicine treatments included homeopathy, relaxation therapy (including guided imagery), acupuncture and magnetic therapy.

Some of the medicine treatments reduced the number of hot flushes. The authors of the review said that relaxation therapy was the only non medicine treatment that seemed to reduce the number and severity of hot flushes. But this was just 1 study and we need more research to know whether guided imagery can reduce hot flushes in women with breast cancer.

You can read the report of the review of treatments for hot flushes on the Cochrane Library website link below.

Some studies suggest that imagery can directly affect the immune system.

But, there is no scientific evidence to prove that these techniques can cure cancer or any other disease.

Some well designed studies have shown that imagery can improve quality of life for some people, but not found that it can help them live longer.

What it costs

Many health care organisations or cancer support groups provide visualisation sessions led by a health professional for free.

Some organisations may make a small charge or ask for a donation.

Finding a visualisation therapist

Anyone can call themselves a visualisation therapist, so be careful about paying a therapist without checking what training they’ve had.

There are specific courses for training people to become experts in relaxation, visualisation and guided imagery techniques. Some nurses and doctors have training in this area. And psychotherapists, psychologists and psychiatrists all have training in the use of relaxation and visualisation techniques.
