What is Actinic Keratosis (Solar Keratosis)?

Effective actinic keratosis treatment begins with understanding what these common skin changes are. An actinic keratosis, also known as a solar keratosis, is a rough, scaly patch on the skin that develops after years of sun exposure. It is considered a precancerous condition, which means it is not yet skin cancer but has the potential to become a type of cancer called squamous cell carcinoma (SCC). These lesions typically appear on areas of the body most frequently exposed to the sun, such as the face, lips, ears, scalp, neck, and the back of the hands and forearms.

The appearance of actinic keratoses can vary. They may be flat or slightly raised and can range in colour from skin-toned to pink, red, or brown. Often, they are more easily felt than seen, with a texture similar to sandpaper. Whilst most are harmless, their presence is a key indicator of cumulative sun damage and an increased risk for developing skin cancer. People with fair skin, a history of sunburn, or those who have spent a lot of time outdoors for work or leisure are at a higher risk. Recognising these sun damage lesions early is an important step in managing your skin health and seeking appropriate medical advice.

How Does Sun Exposure Cause Precancerous Lesions?

Sun exposure causes these precancerous lesions, known as actinic keratoses, through long-term damage from ultraviolet (UV) radiation. UV rays, either from the sun or tanning beds, damage the DNA within skin cells called keratinocytes. This cumulative damage can cause the cells to grow abnormally, forming the characteristic rough, scaly patches.

Whilst a single actinic keratosis has a low risk of progressing to squamous cell carcinoma (SCC), having multiple lesions increases this risk. It is estimated that up to 60% of SCCs develop from a pre-existing actinic keratosis. The link between these sun damage lesions and skin cancer is why early detection and management are so important. Here is a breakdown of the process:

• UV Radiation Exposure: Chronic exposure to UVA and UVB rays is the primary cause.
• DNA Damage: The radiation alters the genetic material in the outer layer of skin cells.
• Abnormal Cell Growth: Damaged cells begin to multiply in a disordered way, forming a visible lesion.
• Immune System Suppression: Extensive sun exposure can also weaken the skin's local immune response, making it less able to repair damage and eliminate abnormal cells.
• Risk of Progression: If left untreated, the abnormal cell growth can progress through the skin's basement membrane, becoming an invasive squamous cell carcinoma.
• Cumulative Effect: The damage builds up over many years, which is why actinic keratoses are more common in people over the age of 40.

Identifying Actinic Keratosis: Symptoms and Diagnosis

Recognising the signs of actinic keratosis is key to seeking timely advice. The lesions can present with a range of symptoms. Most commonly, an actinic keratosis feels like a rough, dry, or scaly patch of skin. Its texture is often compared to sandpaper and may be easier to feel than to see, especially in its early stages. Visually, it can appear as a flat or slightly raised spot that may be pink, red, or brown. Some lesions can be itchy, tender, or cause a burning sensation. In some instances, they may become inflamed, bleed, or develop a crust.

A diagnosis is typically made during a clinical examination by a specialist. During your consultation, a thorough inspection of your skin will be performed. A handheld magnifying tool called a dermatoscope is often used to get a more detailed view of the skin's surface and the patterns within the lesion. This helps to distinguish an actinic keratosis from other skin conditions.

In most cases, a diagnosis can be confirmed visually. However, if a lesion is particularly thick, tender, ulcerated, or growing quickly, it may be suspicious for an evolution to squamous cell carcinoma. In such circumstances, a skin biopsy may be recommended. This is a straightforward procedure where a small sample of the lesion is removed under local anaesthetic and sent to a laboratory for analysis. With extensive experience in both the NHS and private practice, Mr. Vijayan is adept at accurately diagnosing skin lesions and determining the most appropriate course of action.

Non-Surgical Actinic Keratosis Treatment Options

For many patients, non-surgical actinic keratosis treatment is a highly effective option. These methods are particularly useful when there are multiple lesions or a wider area of sun damage, often referred to as 'field change'. The choice of precancer treatment depends on the number, thickness, and location of the lesions, as well as patient preference and lifestyle factors. Common non-surgical approaches include topical creams, cryotherapy, and photodynamic therapy.

Topical Creams and Gels

Medicated creams are applied directly to the skin to treat visible and invisible lesions over a broad area. Common options include:

• 5-Fluorouracil (5-FU): This is a cytotoxic agent that destroys rapidly growing abnormal cells. Treatment typically involves applying the cream for several weeks, which causes an inflammatory reaction (redness, crusting, and peeling) as it works.
• Imiquimod: This cream stimulates the body's own immune system to recognise and destroy the precancerous cells. The application schedule varies but also results in a local skin reaction.
• Diclofenac Gel: An anti-inflammatory gel that is generally better tolerated than other topical treatments, though it may be less potent and requires a longer treatment course.

Cryotherapy

Cryotherapy is one of the most common treatments for individual, well-defined actinic keratoses. It involves the precise application of liquid nitrogen to freeze and destroy the abnormal cells. The treated area will typically blister and then form a scab which falls off within a few weeks, allowing healthy new skin to emerge. The procedure is quick and performed in the clinic.

Photodynamic Therapy (PDT)

PDT is a two-step procedure used for multiple lesions on the face or scalp. A light-sensitising cream is applied to the affected skin, which is then activated by a specific wavelength of light. This process selectively destroys the sun-damaged cells. The skin will be red and sensitive for several days afterwards, requiring strict sun avoidance.

Actinic Keratosis Surgery: When is Excision Needed?

Whilst many actinic keratoses respond well to non-surgical treatments, surgery may be recommended in specific situations. A surgical approach is often considered for thicker, more prominent lesions (hyperkeratotic types), or for those that have not cleared with topical treatments or cryotherapy. Surgery is also the preferred option if there is any suspicion that a lesion may have already progressed to an early-stage squamous cell carcinoma, as it allows for a sample to be sent for histological analysis to confirm the diagnosis.

The decision on whether all AKs should be removed is tailored to the individual. Factors such as the number of lesions, their appearance, and your overall skin health and risk factors are all taken into account. The primary goal of treatment is to prevent progression to skin cancer, relieve any symptoms, and improve the appearance of the skin.

There are two main surgical techniques for keratosis excision:

• Curettage and Cautery: This procedure involves using a sharp, spoon-shaped instrument (a curette) to scrape away the abnormal tissue. An electric current (cautery) is then used to control any bleeding and destroy any remaining abnormal cells. It is performed under local anaesthetic.
• Surgical Excision: For more suspicious or larger lesions, complete surgical excision may be necessary. Mr. Vijayan will numb the area with local anaesthetic before carefully cutting out the lesion and a small margin of surrounding healthy tissue. The wound is then closed with fine stitches. As a Consultant Plastic Surgeon, Mr. Vijayan's FRCS (Plast) qualification signifies his expertise in techniques for surgical excision of skin lesions that prioritise not only complete removal but also the best possible aesthetic outcome.

What is Recovery Like After AK Removal in London?

The recovery process following AK removal varies significantly depending on the treatment method used. Understanding what to expect can help you plan accordingly and ensure a smooth healing period. It is important to follow the specific aftercare instructions provided to you to support healing and achieve the best possible result.

For non-surgical treatments like topical creams (5-FU, Imiquimod), the recovery is part of the treatment itself. Patients should anticipate a period of skin reaction, which is a sign the medication is working. This typically involves redness, swelling, crusting, or peeling in the treated area, which can last for several weeks. Photodynamic therapy (PDT) results in a similar reaction, with pronounced redness and sensitivity for several days to a week.

For lesion-directed procedures, the recovery is more localised. After cryotherapy, the treated spot may form a blister, followed by a scab that usually falls off within one to three weeks, depending on the location. Healing on the face is generally quicker than on the hands or lower legs. For curettage and cautery, a scab will form over the treated area, which should be kept clean and dry. It will heal over a few weeks, potentially leaving a small, flat scar.

Following surgical excision, you will have a small dressing over the stitches. The area should be kept clean and dry. There may be some mild bruising or swelling initially. Stitches are typically removed after 5 to 14 days, depending on the location of the lesion. Mr. Vijayan will provide detailed advice on wound care and scar management to ensure the incision heals as neatly as possible, minimising its long-term visibility.

Comparing Patient Experiences with AK Treatments

Choosing the right actinic keratosis treatment involves balancing effectiveness with the patient experience, including factors like discomfort, downtime, and cosmetic results. As every individual's skin and circumstances are unique, Mr. Vijayan ensures a collaborative approach, discussing the benefits and drawbacks of each option to create a personalised plan. Here is a comparison to help you understand the different experiences.

Topical Creams (e.g., 5-FU, Imiquimod)

• Patient Experience: This requires a commitment of several weeks of home application. The resulting inflammation can be uncomfortable and visually prominent, causing redness, scabbing, and peeling. Some patients experience itching or a burning sensation.
• Downtime: Social downtime is common due to the appearance of the skin during the treatment phase. Strict sun avoidance is essential.
• Cosmetic Outcome: Excellent. Once healed, the skin texture is often significantly improved, as the cream treats both visible lesions and underlying subclinical damage.

Cryotherapy (Freezing)

• Patient Experience: The procedure itself involves a brief, sharp, stinging sensation. Afterwards, the area may feel tender. A blister or scab forms, which can be noticeable.
• Downtime: Minimal. Most activities can be resumed immediately. A small dressing may be used for comfort.
• Cosmetic Outcome: Generally very good for single spots. There is a small risk of a permanent white mark (hypopigmentation) or, less commonly, a small scar, especially if a deep freeze is required.

Surgical Excision

• Patient Experience: The procedure is performed under local anaesthetic and is painless. Some mild soreness may be present for a day or two after the anaesthetic wears off.
• Downtime: Minimal, though strenuous activity may need to be avoided for a short period depending on the location and size of the excision. You will have stitches that require removal.
• Cosmetic Outcome: This will always leave a scar. However, with the specialist skills of a plastic surgeon, the scar is meticulously planned and sutured to be as fine and discreet as possible, often hidden in natural skin creases.

Long-Term Actinic Keratosis Management and Prevention

Treating existing actinic keratoses is only one part of the journey. Because these lesions are a marker of significant sun damage, you are at a higher risk of developing new ones in the future, as well as other forms of skin cancer. Therefore, long-term management focuses on surveillance and robust prevention strategies.

Recurrence is common, as new lesions can develop in the same sun-damaged 'field' of skin. Even lesions that seem to disappear on their own can return. It is vital to establish a routine of regular self-examination, checking your skin monthly for any new or changing spots. Look for rough patches, non-healing sores, or any spots that change in size, shape, or colour. Regular follow-up appointments with your specialist are also crucial to monitor your skin and catch any new developments at the earliest stage.

Prevention is the most powerful tool in your long-term plan. Protecting your skin from further UV radiation is essential to minimise the risk of new lesions forming.

• Use High-SPF Sunscreen Daily: Apply a broad-spectrum sunscreen with an SPF of at least 30 (preferably 50) to all exposed skin every single day, regardless of the weather. Reapply every two hours when outdoors.
• Wear Protective Clothing: Long-sleeved shirts, trousers, and wide-brimmed hats provide a physical barrier against harmful UV rays.
• Seek Shade: Avoid direct sun exposure during the peak hours of 11 a.m. to 3 p.m. when UV radiation is strongest.
• Avoid Tanning Beds: Artificial tanning sources emit harmful UV radiation and should be avoided completely.
