Private Skin Cancer Screening in London

Medically Reviewed by Doctor Björn Thomas, GMC: 7084005

At the Thomas Clinic, we see a lot of patients who have noticed a new mole, a changing mark, or a sore that is not healing. They want a diagnosis and reassurance.

If you are worried about your skin, it is completely understandable to feel anxious. A screening aims to check that a lesion is not cancerous and to replace uncertainty with a clear plan.

At any of the three clinic locations we operate from in London, we offer private skin cancer screening in a discreet, reassuring setting. Going private can help you avoid long waiting times and access a thorough review within days, not weeks or months.

Thomas Clinic – Your Skin Cancer Specialist in London

At the clinic, we combine clinical thoroughness with a calm, sensitive approach, because skin cancer worries are not just a quick check for most people. We make sure you have time to explain exactly what you have noticed, and we talk you through what we are looking for.

Patients often tell us they value the clear explanations we offer, alongside our straightforward approach, and feeling truly listened to during the process.

Book a Private Skin Cancer Screening in London

Booking is simple and confidential. You can self-refer directly, without a GP referral, and book by phone or via the online form.

During your consultation, we perform a head-to-toe skin examination using dermoscopy. Dermoscopy is painless and non-invasive, and it allows us to examine lesions in much more detail so we can distinguish harmless marks from those that need closer attention. 

You will leave with clear, understandable feedback and next steps, even if that next step is simply reassurance.

If we identify a suspicious lesion, we will explain the safest option, such as arranging a biopsy or excision under local anaesthetic. Early detection often means treatment is smaller and simpler.

Common Signs Of Skin Cancer

Recognising the early signs of skin cancer empowers you to safeguard your health. When detected promptly, most skin cancers are highly treatable and often completely curable. Early identification and professional evaluation greatly improve outcomes and provide immediate reassurance.

The common types of skin cancer include:

Basal Cell Carcinoma (BCC)

BCC is the most common form of skin cancer. Classically, it appears as a pearly, skin-coloured bump (papule) that may easily bleed as it grows. Other variants include flat, red lesions commonly found on the trunk, pigmented lesions, or firm, scar-like (sclerotic) lesions. 

BCC lesions around the mouth, eyes, ears, and nose, especially if poorly defined, may be more challenging to remove completely. These lesions may require Mohs Micrographic Surgery. Although BCCs can grow locally, it is very rare for them to spread to other parts of the body. Typically, these cancers appear alongside otherwise healthy-looking skin.

Squamous Cell Carcinoma (SCC)

SCCs are the second most common type of non-melanoma skin cancer, strongly linked to cumulative sun damage. They frequently develop from precancerous lesions known as actinic keratoses – red, scaly lesions confined to the epidermis. 

SCC typically presents as white or red, scaly, tender lumps, often accompanied by other visible sun damage. One subtype, keratoacanthoma, grows rapidly and resembles a volcano-like bump with a rough keratin plug in its centre. 

Another subtype, squamous cell carcinoma in situ (Bowen’s disease), appears as a persistent, scaly patch resembling psoriasis or eczema and shows minimal change over time. Bowen’s disease is considered ‘pre-cancerous’

Melanoma

Melanomas are less common but potentially life-threatening if not identified and treated early. While some melanomas develop from pre-existing moles, the majority appear spontaneously on normal skin. 

Identifying melanoma can be challenging, especially in individuals with numerous moles. However, most melanoma cases occur in people with relatively few moles. An important diagnostic principle is the “ugly duckling” concept—identifying moles that look distinctly different from others.

Dermatologists use a dermatoscope,a device providing polarised bright light and magnification, to detect atypical melanoma features. Dermoscopy significantly enhances diagnostic accuracy, enabling earlier and smaller melanoma detection. 

A definitive melanoma diagnosis requires a laboratory biopsy examination. Additionally, standardised photographic documentation, known as mole mapping, has improved the detection of new or changing moles over time.

A dermatologist’s skill is critical in selecting which lesions to focus on during examination. 

While machine learning and AI technologies are advancing in dermatology, they remain in early developmental stages, and expert human assessment is still essential. Notably, the pigmented lesion that initially concerns a patient may not always be the most clinically significant.

Signs to Watch For:

Arrange a professional skin check promptly if you notice any of the following:

New or changing moles (ABCDE Rule for Melanomas):

• A – Asymmetry: Two halves of the mole differ in shape or size.
• B – Border: Edges appear irregular, blurred, notched, or ragged.
• C – Colour: Uneven pigmentation with shades of brown, black, pink, red, white, or blue.
• D – Diameter: Typically larger than 6mm (size of a pencil eraser), though nowadays smaller melanomas are frequently identified and diameter is used less as an important feature.
• E – Evolving: Any noticeable change in size, shape, colour, or elevation. This is one of the most important features.

These features might not be present in every melanoma, so it’s vital to compare the lesion against what is normal for you. A comprehensive skin check involves examining all lesions thoroughly. 

Melanomas often look distinctly different and more concerning compared to other moles. Patients and their relatives play a critical role by understanding and identifying these changes early. Always get any lesion that stands out as different or changing professionally evaluated.

Teledermatology is commonly used to assess one to three suspicious lesions. Often, the dermatologist identifies a lesion of concern that is different than the one you or your specialist are concerned about. However, there is no substitute for a thorough, in-person skin examination by a dermatologist.

Itching, bleeding, or crusting skin lesions:

• Lesions becoming itchy, bleeding, crusty, or uncomfortable warrant prompt professional evaluation. These symptoms are frequently observed in thicker melanomas, commonly occur in basal cell carcinomas (BCC), and occasionally in squamous cell carcinomas (SCC).

Non-healing sores or new growths:

• Persistent sores, lumps, or ulcers that do not heal within 3–4 weeks.
  • BCC: Often small, shiny, pearly bumps or sores that repeatedly bleed and scab.
  • SCC: Typically firm, red, scaly patches or wart-like growths prone to bleeding or ulceration.
  • Multiple rough, scaly lesions in sun-exposed areas may indicate actinic keratosis, a marker of sun damage that can progress to skin cancer.

New or unusual skin marks:

• Newly developed moles, unusual lesions, or rapidly changing pigmented areas, including darker areas beneath nails appearing without injury, should always be professionally checked.

Prompt Professional Evaluation: Early Action for Peace of Mind

If you’re concerned about any skin changes, prompt professional evaluation is crucial. Skin cancer screening at the Thomas Clinic is comfortable and straightforward. Our specialists use non-invasive dermoscopy technology to examine your skin thoroughly, providing immediate clarity and reassurance.

If further assessment is required, minor biopsies or excisions are performed swiftly under local anaesthetic, ensuring comfort throughout. Early detection can significantly improve treatment outcomes. Most melanomas detected early can be fully cured through minor surgery, and non-melanoma skin cancers (BCC and SCC) are routinely treated effectively.

Acting early ensures clear feedback and immediate professional guidance. The Thomas Clinic supports you through every step, replacing uncertainty with the peace of mind that comes from proactive healthcare.

Common Areas Skin Cancer Can Develop

Skin cancer can develop anywhere, but certain areas are especially prone due to higher sun exposure and specific vulnerabilities. Regular self-checks and professional screenings are strongly advised, particularly for the following common sites:

• Face and Neck: Frequently exposed to sunlight, significantly increasing the risk of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).
• Scalp: Particularly vulnerable if hair is thinning or absent; this area is easily overlooked during self-examinations.
• Arms and Hands: Often exposed without adequate sun protection, leading to increased risk over time.
• Legs and Feet: Melanomas commonly develop on legs, especially among women. Additionally, the soles of the feet can be affected, even though this area receives minimal sun exposure.
• Back and Shoulders: Common sites for melanoma, particularly in men, likely due to intermittent but intense sun exposure.
• Nail Pigmentation: Any unusual pigment appearing beneath the nails—especially dark lines extending along the nail or emerging at the base of the nail—should be professionally assessed without delay.

Early detection dramatically improves treatment outcomes, underscoring the importance of regular checks. If you notice any new or changing marks, consult a specialist promptly.

How Skin Cancer Screening Works

Initial Consultation

We start by listening to your concerns, discussing relevant history, sun exposure, and risk factors.

Detailed Skin Examination

A careful head-to-toe check is performed, including areas that are easy to miss (back, behind ears, between fingers and toes). Dermoscopy is used throughout. The consultation typically takes around 10 to 20 minutes, and we make sure you have time to ask questions.

Follow-Up And Results

We explain findings immediately. If a biopsy is needed, it can usually be arranged quickly (typically within the week). Biopsy results are typically available within 7 to 10 days, and we will discuss the results and next steps clearly.

Mole Mapping

If mole mapping is appropriate for you, we can arrange it alongside your review using the Vectra 360 3D mole mapping scanner at Welbeck, to help track changes over time.
