Liver lesions are abnormal areas or growths of tissue within the liver, often appearing as masses on scans such as ultrasound, CT, or MRI. They’re commonly referred to as hepatic lesions or hepatic masses in medical reports and are discovered incidentally in many cases during checks for unrelated issues.
The good news is that most liver lesions are benign (non-cancerous) and completely harmless — they don’t cause symptoms or require treatment. Benign ones, like haemangiomas or simple cysts, are far more common than malignant (cancerous) types. Malignant liver lesions are less frequent but benefit hugely from early identification and specialist care.
Getting an accurate diagnosis early avoids worry and ensures the right management approach, be that reassurance, monitoring, or targeted treatment. At Leaders in Liver Health, our UK hepatologists provide expert, calm assessment using advanced imaging techniques to give you clear answers quickly.
Liver lesions are any visible abnormality of liver tissue seen on imaging indicating a mass, or a change that differs from normal surrounding liver.
They can be described as a hepatic mass, lump on liver, or even a “liver shadow” on a scan report. This simply means an area that stands out and needs further characterisation to understand what it is.
Liver lesions vary hugely: some are tiny and insignificant, others larger; some solid, some fluid-filled. They are not a diagnosis in themselves, but a finding that could represent a range of conditions, mostly harmless variations (like blood vessel clusters), cysts, infections, or benign growths, but also rarely tumours.
Many people have liver lesions without ever knowing, as they’re often picked up by chance. A “liver shadow” on ultrasound or other scans usually prompts additional tests like CT or MRI to clarify the nature safely and non-invasively.
With modern imaging, most can be confidently identified without invasive procedures, bringing peace of mind.
No, most liver lesions are not serious at all.
Many liver lesions are harmless and never cause any problems throughout life. Benign liver lesions (non-cancerous) are very common — things like haemangiomas or cysts — and typically stay stable without intervention.
A small proportion turn out to be malignant liver lesions (cancerous), which do require specialist attention and tailored management. The key is accurate diagnosis early on.
Seriousness depends on:
Specialist review with contrast-enhanced scans usually sorts this out quickly and reliably, preventing unnecessary concern.
Liver lesions are broadly divided into benign (non-cancerous) and malignant (cancerous). Benign types are much more common and usually need little or no action.
Hepatic Adenoma — A rarer benign hepatic mass linked to hormones (e.g., oral contraceptives), obesity, or the metabolic syndrome. It can grow larger and has a small risk of rupture. There are several subtypes now identified, and some have a risk of malignant change to a liver cancer, particularly if they are becoming large. Monitoring is required for all hepatic adenomas, surgical removal may be recommended for those that are causing symptoms or are a risk for malignant change.
Most liver lesions do not cause symptoms — especially benign ones, which are often silent lifelong discoveries.
When symptoms occur (more typical with larger, malignant, or complicated hepatic mass), they can include:
Benign liver lesion rarely cause symptoms; malignant ones are more likely to produce noticeable effects but may also be asymptomatic in the early stages. If you are experiencing any persistent symptoms, specialist hepatology review imaging will bring clarity quickly.
Diagnosis of liver lesions follows a logical, step-by-step path using non-invasive imaging first.
is highly individualised many need none at all.
(hemangiomas, small cysts, FNH) require only reassurance. They’re stable and harmless; periodic scans may confirm no change, but often one scan is enough and monitoring is not needed.
For certain lesions (e.g., hepatic adenomas), follow-up imaging tracks is needed to track stability and assess for any concerning changes.
Ablation (radiofrequency/microwave to destroy targeted tissue) suits some symptomatic benign or early malignant lesions — no big incisions, quicker recovery.
Resection (removal) is considered for large symptomatic benign lesions, high-risk adenomas, or malignant ones. For malignancies like HCC or metastases, surgery may combine with other therapies (targeted drugs, chemotherapy, immunotherapy), or medications therapy alone is used without surgery
The goal is always the least invasive effective approach our specialists tailor plans to your specific lesion type and health.
Most liver lesions are not cancerous.
Benign liver lesions such as hemangiomas (the most common), cysts, and FNH make up the vast majority of findings and are entirely non-cancerous. They’re often incidental and pose no threat.
Malignant liver lesions are less common but include primary cancers (HCC) or secondary spread (metastases). These require specialist staging and treatment but benefit from early detection.
Imaging (especially contrast MRI/CT) reliably differentiates them in most cases for example, hemangiomas show characteristic “light bulb” enhancement patterns. This avoids unnecessary worry while ensuring prompt care if needed.
See a liver specialist promptly if you have:
Red flags like these, or the finding of any new liver lesion in the liver warrant expert review. Early diagnosis allows precise characterisation, prevents complications, and often means simpler management many turn out benign with just monitoring.
Don’t hesitate specialist input brings clarity and reassurance fast.

From benign reassurance to advanced malignancy management, our multidisciplinary approach ensures comprehensive support. Trust us for calm, expert guidance every step of the way.
is an abnormal area of tissue that appears different from normal liver on scans. It can be benign (harmless) or rarely malignant, but most need only assessment for peace of mind.
A liver mass refers to a visible lump or growth in the liver. Most are benign and harmless, but specialist imaging confirms the type and whether any action is needed.
No, many liver lesions are harmless and never cause issues. Benign ones are very common; only a minority are malignant and require treatment.
Benign liver lesions like cysts or haemangiomas usually stay stable rather than disappear. They rarely resolve but often need no treatment.
A “liver shadow” on ultrasound is an area that looks different or darker/brighter than normal liver tissue. It usually prompts further scans (CT/MRI) to clarify what it is.
Yes the great majority of liver lesions are benign (non-cancerous), such as haemangiomas, cysts, and FNH. They are common and typically harmless.
Liver lesions are mainly picked up on an ultrasound and usually require subsequent CT or MRI for detailed characterisation. Blood tests can help, and occasionally a biopsy is needed if imaging is unclear.
If a scan has revealed a liver lesion or a hepatic mass, or you’re worried about symptoms or abnormal tests, early specialist evaluation is key.
