VR for Cancer Pain Management: The Evidence for Clinicians

Pain remains one of the most challenging complications in oncology care. Many patients with cancer report pain at earlier disease stages, affecting up to 60-70% among those with advanced disease. Pharmacological management, particularly opioids, has long been the default. 

The limitations are well documented. Tolerance, dependency risk, side effects, and a persistent gap between prescription and relief are pushing clinicians toward adjunct approaches. One gaining serious research traction is VR for cancer pain management.

This is not a wellness pitch. It is a clinical question backed by trial data.

How VR Is Changing Pain Management

Cancer pain is not just a single entity. The three types of pain that are associated with cancer are somatic pain due to tumour invasion, visceral pain due to organ involvement, and neuropathic pain due to chemotherapeutic nerve damage, radiation plexopathy, or nerve root involvement by the tumour. A person may suffer from multiple types of pain simultaneously. And what adds to the complexity of all this is the psychosocial element.

Virtual reality pain relief oncology applications work differently. Two frameworks explain the mechanism. The first is Gate Control Theory: the nervous system contains a neurological gateway that modulates pain signal transmission. 

Distraction and positive emotions help close down this gate, limiting pain perception. The other theory here is called the Attention Capacity Theory. In humans, attentional resources are limited. In the case when the attentional capacity is being occupied by the virtual reality environment, leaving fewer attentional resources available for pain processing.

Intercortical modulation has been identified through research. Virtual reality is able to engage attention, emotion, memory, and multisensory inputs simultaneously, affecting the pain matrix across cortical and subcortical networks, beyond spinal-level processing. This is why VR pain distraction therapy is more effective than passive distraction such as flat screen video.

Clinical Evidence Supporting VR for Cancer Pain Management 

Some clinical research demonstrates that virtual reality can safely and effectively reduce pain in patients undergoing cancer treatment. 

The Groninger RCT (2024)

The most recent and pertinent evidence comes from a 2024 randomized controlled trial published in Cancer (American Cancer Society). The trial was conducted under the supervision of Dr. Hunter Groninger of Georgetown University and tested 128 adult subjects diagnosed with active cancer and suffering from moderate to severe pain symptoms (≥4/10) 0 for no pain and 10 for worst possible pain. 

Subjects were randomized into two groups, where one group underwent 10 minutes of VR therapy in relaxing environments, whereas the other group received 10 minutes of 2D guided imagery through an iPad as the control condition.

In terms of outcomes, patients in the VR group showed a mean pain relief of 1.4 points while those in the iPad group showed 0.7 points of mean pain relief; a difference that was found statistically significant (p = 0.03). 

Moreover, the effects of reduced pain lasted for up to 24 hours in the VR group post one therapy session without being seen in the control group even after controlling for age, opioids, metastasis, and consultations.

Systematic Review (2025)

A 2025 PRISMA-based systematic review in Medicine (Baltimore) reviewed 497 articles and included 22 articles: ten randomized controlled trials and 12 quasi-experimental designs. The review addressed cancers of the breast, cervix, colon and rectum, haematologic, gastrointestinal, and urogenital systems. VR was found to be effective in reducing pain intensity irrespective of the category of patients, with the greatest effect on procedure-related acute pain.

Chemotherapy Infusion Clinic 

A randomised controlled trial in the Clinical Journal of Oncology Nursing studied 90 patients undergoing chemotherapy in an outpatient infusion setting. The study group received a 12-minute VR session during infusion. 

There were clear reductions in both pain and stress levels, supported by objective heart rate measurements, not self-reports alone. The researchers pointed out the promise VR offers for decreasing the burden of opioids required in the treatment of cancer patients.

Brain Imaging Confirmation (2025)

A 2025 study involving 41 cancer patients found that over 75% reported pain reduction exceeding the clinically relevant 30% threshold. Brain imaging confirmed changes in pain-related neural circuits, adding neurobiological support to what had previously rested on behavioural theory.

Clinical Benefits Across Oncology Patient Populations

Evidence suggests that virtual reality provides meaningful symptom relief across multiple oncology settings and patient groups, with consistent improvements in pain and anxiety outcomes.

This breadth matters. Cancer pain technology via VR is not a single-indication tool; it spans hospitalised adults, infusion clinic patients, palliative settings, and children undergoing repeated painful procedures.

Practical Considerations Before Using VR in Oncology 

Even though VR is safe and tolerable, clinicians must determine if patients are suitable to use it in their treatment. 

Contraindications: Active vomiting or nausea, presence of seizures or epilepsy, significant cognitive impairment, claustrophobia, and isolation due to infection.

Session length: Existing studies use 10–12 minutes. No standardised dosing protocol exists yet; whether repeated use accumulates benefit or intermittent use is superior remains an open question.

Content type: Active, interactive environments produce stronger analgesic effects than passive ones. Calm and engaging content outperforms neutral visuals.

What VR does not replace: Immersive therapy pain management using VR is an add-on in a pain management protocol and not a basis for delaying optimization of analgesics or medication withdrawal.

Could VR Support Your Oncology Rehab Programme?

VR provides an alternative approach to pain relief that has been proven through randomised trials and physiologically, and has been consistently beneficial in multiple oncology groups. Results vary by patient suitability, content selection, and integration into existing care protocols. An assessment is conducted to determine whether VR therapy is appropriate for an individual's pain profile and treatment stage.
