Skin cancer screening: what a skin check actually is
A skin cancer screening is a structured examination in which a doctor looks over the whole surface of your skin for anything unusual. The point is early detection: spotting skin cancer or its early signs while a change is still small and easier to treat. It is about finding a problem early, not about treating it.
The UK does not run a national screening programme for skin cancer. The NHS instead advises seeing your GP if you notice a new growth or a mole that changes in size, shape or colour, or if a spot bleeds, itches or does not heal. If needed, the GP can refer you to a dermatologist for a closer look.
This matters because skin cancer is one of the most common cancers, and melanoma in particular is far more treatable when caught early. A regular look at your own skin, combined with a professional check when something concerns you, is the practical version of screening for most people in the UK.
Who should be checked - and how it works in the UK
Anyone can develop skin cancer, but some people benefit from more regular checks: those with very fair skin, a history of sunburn or sunbed use, a large number of moles or atypical moles, a weakened immune system, or a personal or family history of skin cancer. If that describes you, it is worth discussing a routine with your GP or dermatologist.
On the NHS, the usual path starts with your GP. If a mole or spot looks suspicious, you can be referred to a dermatologist, in some cases through an urgent referral for suspected cancer. The specialist may examine the area more closely and, if there is real concern, remove it so it can be examined under a microscope. That biopsy is the only way to know for certain.
Private skin checks and mole-mapping services are also available and are paid for out of pocket. They can suit people who want a regular full-body review, but they are an individual choice rather than a medical requirement.
Fair skin, freckling, many moles, past sunburns or sunbed use, a weakened immune system and a family history of melanoma all raise risk. If several apply to you, ask your GP how often you should be checked.
The skin check step by step
The appointment usually starts with a few questions: any spots you have noticed, your sun exposure, past sunburns, sunbed use and whether skin cancer runs in your family. This helps the clinician judge your risk.
The examination itself is a head-to-toe visual inspection of the skin under good light. It includes places that are hard to see yourself, such as the scalp, behind the ears, the back, between the toes and the soles of the feet. A standard skin check is painless and takes only a few minutes. A dermatologist may also use a dermatoscope, a handheld magnifier, to study individual moles more closely.
If a spot looks suspicious, the next step is not a diagnosis on the spot but further assessment. Usually a small sample or the whole lesion is removed and examined in a laboratory. Only that biopsy can confirm or rule out skin cancer.
A basic skin check is a visual, naked-eye examination of your whole skin. Dermoscopy and photographic mole mapping are additional techniques that a dermatologist or private clinic may offer, particularly if you have many moles.
What does a skin check cost?
Seeing your GP about a mole and any NHS referral that follows are free at the point of use. If a lesion needs to be removed and tested because of clinical concern, that care is provided by the NHS.
Costs come into play with private services. A private full-body skin check or a mole-mapping session is paid for yourself, and the price depends on the clinic and how detailed the assessment is, so it is worth asking for a clear quote in advance. Private care can mean shorter waiting times or a scheduled annual review, but it is optional.
Whichever route you choose, be wary of add-ons whose benefit is not explained to you. Ask what a particular test would actually change in your situation before agreeing to it.
Private skin checks and mole mapping are optional and self-funded. You are entitled to a clear explanation and an upfront price. A test is only worth it if you understand what it adds for you.
Dermoscopy and mole mapping: who benefits?
Dermoscopy uses a handheld device that magnifies a mole and reveals structures below the surface that the naked eye cannot see. In experienced hands it helps tell harmless moles from ones that need attention.
Mole mapping, or digital documentation, photographs and records your moles so changes can be compared over time. It is most useful for people with a very large number of moles, atypical moles, or a higher risk such as previous melanoma or a strong family history. For most people, the whole-body visual check remains the foundation, and extra techniques are an individual decision based on risk.
How to prepare for your appointment
So the clinician can see every area clearly, come with clean skin. Remove make-up and nail polish, because the nails are part of the exam and skin cancer can also develop under a nail. Wear your hair loose and leave bulky jewellery at home.
Before you go, note any spots that are new or have changed since you last looked. Mention regular medication, any condition that weakens your immune system, past skin cancers, family cases and frequent sunburns or sunbed use. Do not feel awkward about the areas people tend to forget, such as the scalp, soles and between the toes. It is also a good moment to ask how to keep an eye on your skin between visits.
- No make-up, remove nail polish
- Hair loose, remove bulky jewellery
- Note new or changing spots
- Mention medication, past skin cancer and family history
Between checks: self-examination and warning signs
A lot can change between professional checks, so it helps to look over your own skin regularly, around once a month. A hand mirror and a partner make it easier to see your back and scalp.
A well-known guide is the ABCDE rule: A for asymmetry, B for an irregular border, C for more than one colour, D for a diameter larger than about six millimetres, and E for evolving, meaning a spot that changes over time. The ugly duckling - a mole that looks different from all the others - is another warning sign. Any new, growing, bleeding, itching or non-healing spot deserves a professional check without waiting.
Self-checks and digital tools sharpen your awareness, but they do not replace an examination by a doctor. Think of them as a way to notice change sooner and raise it in good time.
- A - asymmetry of shape
- B - irregular or blurred border
- C - more than one colour
- D - diameter over about 6 mm
- E - evolving or changing over time
An important note about this guide
This article is intended to inform you and to encourage early detection. It does not replace medical advice, examination or diagnosis. Neither a self-check nor a digital tool can reliably rule out or confirm skin cancer - only a medical assessment can, and in a suspected case that means a biopsy.
If a spot looks suspicious to you or has changed, book an appointment with a GP or dermatologist regardless of when you were last checked. For a spot that grows quickly, bleeds or will not heal, do not wait.
The information in this guide is general and is not individual medical advice. If you have symptoms or a skin change that concerns you, please see a doctor.
