Cancer surgery patients face a particular set of challenges that make prehabilitation not just beneficial but, in many cases, clinically essential. The combination of disease-related deconditioning, treatment-related nutritional depletion and the psychological weight of a cancer diagnosis means that patients undergoing surgery for cancer arrive at the operating table in a substantially more compromised position than many other surgical groups. This post examines what prehabilitation for cancer surgery involves, what the evidence shows, and why the pre-operative window is one of the most important and most underused opportunities in cancer care.
Why Cancer Surgery Patients Are Different
The physiological challenges facing cancer surgery patients begin well before the operation itself. Cancer and its associated treatments frequently cause sarcopaenia (loss of muscle mass), malnutrition and reduced aerobic capacity, even before surgery has taken place. Chemotherapy and radiotherapy, where delivered pre-operatively, compound these effects further. A patient who has spent weeks or months managing the side effects of cancer treatment may have significantly reduced physiological reserve by the time their surgical date approaches.
This matters because physiological reserve is one of the strongest predictors of surgical outcomes. Patients with low reserve face higher rates of postoperative complications, longer hospital stays and slower functional recovery. For cancer surgery patients, who often face more complex procedures with longer recovery trajectories than elective surgical patients, the stakes are correspondingly higher. The gap between where these patients are at diagnosis and where they need to be at surgery is wider than in almost any other surgical group.
Psychological distress compounds the picture significantly. A cancer diagnosis is one of the most psychologically demanding events a person can face. Anxiety, depression and fear are prevalent in this population and are independently associated with worse surgical outcomes, reduced adherence to recovery programmes and higher rates of hospital readmission. Addressing psychological readiness before surgery is not a secondary consideration for cancer patients. For a broader look at how mental health affects surgical outcomes, our post on the role of mental health in surgical recovery examines the evidence in depth.
What the Evidence Shows for Cancer Surgery
In cancer surgery, prehabilitation is not a luxury intervention reserved for the fittest patients. It is a clinical necessity that produces its strongest results precisely in the patients who need it most.
The evidence base for prehabilitation in cancer surgery has grown substantially over the past decade and is now among the strongest in the perioperative field. According to a systematic review published in Surgical Oncology, pre-operative nutritional and physical preparation in patients undergoing major cancer surgery was associated with a 35% reduction in postoperative complication rates compared to standard care. For a patient facing colorectal, oesophageal, gastric, lung or urological cancer surgery, that represents a meaningful reduction in risk.
Hospital length of stay is also consistently reduced. A meta-analysis examining colorectal cancer surgery patients found that those who completed a structured prehabilitation programme had hospital stays that were on average 2.5 to 4 days shorter than control patients. Given that length of stay is both a quality-of-life metric for patients and a major cost driver for health systems, this finding carries significant clinical and economic weight.
Return to functional capacity is the outcome that matters most to patients. Research from McGill University examining colorectal cancer surgery patients showed that those who completed prehabilitation returned to their pre-diagnosis functional baseline significantly faster than those who received rehabilitation alone. This is not simply a statistical finding. It reflects a measurable difference in the time patients spend limited by the effects of surgery rather than living their lives.

The Three Pillars in a Cancer Surgery Context
Physical Conditioning
For cancer surgery patients, physical conditioning must be calibrated carefully to the patient’s current state. A patient who has completed six cycles of chemotherapy cannot follow the same exercise programme as a deconditioned but otherwise healthy orthopaedic patient. Programmes need to begin from a realistic baseline assessment, build gradually and account for fatigue, immunosuppression and any treatment-related toxicities. Even modest improvements in pre-operative fitness produce meaningful reductions in anaesthetic risk and postoperative recovery time.
Cardiopulmonary exercise testing (CPET) is increasingly used in cancer surgery pathways to objectively measure exercise capacity before surgery. The results inform both the surgical plan and the intensity of prehabilitation. Patients identified as high risk through CPET can be directed toward more intensive pre-operative programmes, while those with better reserve can focus on maintaining and building on their existing condition.
Nutrition
Malnutrition is particularly prevalent in cancer surgery populations. Depending on the cancer type and treatment history, rates of pre-operative malnutrition range from 30% in colorectal cancer patients to over 80% in patients with upper gastrointestinal cancers. Protein deficiency, micronutrient depletion and cachexia (cancer-related muscle wasting) all impair wound healing, immune function and the capacity to tolerate and recover from surgery. Nutritional prehabilitation in this group requires targeted supplementation, protein optimisation and, where cachexia is present, specialist dietetic input. For a detailed examination of nutrition in the surgical context, see our post on how nutrition supports surgical recovery.
Psychological Preparation
Structured psychological preparation is a core component of effective cancer surgery prehabilitation, not an optional add-on. Mindfulness-based stress reduction, goal-setting and psychoeducation help patients manage the anxiety of diagnosis and the uncertainty of surgery while building the psychological resilience they will need throughout their recovery. Patients who receive structured psychological support before surgery consistently report lower postoperative pain scores, better adherence to recovery programmes and faster return to meaningful activity.
Access, Equity and the Cancer Prehabilitation Gap
Despite the evidence, access to prehabilitation for cancer surgery patients remains highly unequal across the UK. A 2025 survey mapped prehabilitation services for cancer surgery patients across NHS England and found that provision was patchy, inconsistently resourced and often limited to patients at major cancer centres. Patients treated at district general hospitals or in more rural settings were significantly less likely to have access to a structured pre-operative programme, regardless of their clinical need.
Risk stratification is rarely applied systematically. Patients who would benefit most from prehabilitation, those who are malnourished, sarcopaenic, frail or psychologically distressed, are not consistently identified and referred. The result is that the patients with the highest need are also the patients least likely to receive support. This inequity has measurable consequences in outcomes data.
The Greater Manchester Prehab4Cancer programme represents the most significant attempt to address this at population scale. Operating across a regional cancer network, the programme demonstrates that prehabilitation can be delivered systematically to large cancer surgery populations when the infrastructure and commissioning intent exist. Its outcomes data provides a compelling model for wider rollout. The question is no longer whether it works. It is how quickly the rest of the health system can build the capacity to deliver it. The access gap is examined in full in our post on why 90% of surgical patients miss out on prehabilitation.
How Clovo Can Help
Clovo was built in part to close the access gap that currently leaves most cancer surgery patients without structured prehabilitation. Amy, our AI recovery coach, delivers a personalised multimodal prehabilitation programme across movement, nutrition and mindset from the point of surgical listing. Amy adapts to each patient’s baseline, treatment history, procedure type and risk profile, providing the responsive, evidence-led support that cancer surgery patients need but rarely receive outside of specialist centres. For cancer patients who are also managing active treatment, Amy adjusts programming in real time to account for fatigue, side effects and changing clinical status.
CMO Dr Rebecca Hughes MRCS leads the clinical governance framework that ensures Clovo’s approach to cancer surgery prehabilitation is both evidence-based and clinically safe for this complex population. CEO Rory Skinner and CTO Dr Matthew Higgs-McCallum have built the platform infrastructure that makes this support accessible regardless of where a patient lives or which hospital they attend. To learn how Clovo integrates with existing NHS cancer pathways, see Clovo and NHS integration. To understand how Amy builds a personalised programme for each patient, visit how Clovo builds your personalised recovery plan.
Cancer surgery represents one of the most compelling applications of prehabilitation in modern medicine. The evidence is strong, the need is acute and the gap between what is possible and what most patients currently receive is large. Closing that gap requires both clinical will and the infrastructure to deliver support at scale. Both are now within reach.
