Precancerous lesions laser treatment can be a safe and effective treatment option for selected patients with actinic keratoses and early field cancerisation — but only after proper dermatology assessment. The aim is to remove abnormal cells at the surface of the skin while minimising damage to surrounding tissue and supporting long‑term surveillance.
If you have persistent rough or scaly patches on sun‑exposed areas such as the face, scalp, hands or forearms, laser therapy may help when topical treatments are not suitable or when multiple lesions are present. This is a medical treatment pathway, not a cosmetic service, and always starts with diagnosis, consent, and realistic expectation‑setting.
This page explains when laser treatment is appropriate for precancerous skin lesions, how it works, what results to expect, and how safety is prioritised at every step.
Precancerous skin lesions sit between benign sun damage and invasive skin cancer. Our role is to identify which lesions are suitable for laser therapy, which require biopsy or excision, and how to reduce future risk through surveillance and prevention.
Laser technology can play a role in selected cases — particularly ablative Er:YAG laser therapy targeting abnormal epidermal cells. In some situations, laser may complement topical treatments or photodynamic therapy rather than replace them. This approach is evidence‑based and diagnosis‑first, not device‑led.

Actinic keratoses are rough, sun‑induced lesions caused by abnormal keratinocytes within the epidermis. They commonly affect chronically sun‑exposed skin such as the scalp, forehead, cheeks, ears, hands and forearms. Field cancerisation describes wider areas of damaged skin where subclinical abnormal cells exist beyond visible lesions.
This is why treatment planning often goes beyond treating a single spot and may involve field‑based strategies.

Ablative laser therapy uses controlled laser energy that is strongly absorbed by water within the skin. This allows abnormal surface layers to be vaporised in a controlled manner while limiting damage to surrounding tissue. Used appropriately, laser ablation can clear visible actinic keratoses and reduce the burden of abnormal cells across the treated area.
Laser is not used to treat melanoma and is not a substitute for diagnosis. Any lesion with features concerning for squamous cell carcinoma or basal cell carcinoma requires biopsy or excision.
In patients with repeated or widespread actinic damage, precision resurfacing may be considered. The goal is controlled removal of the affected epidermal layers rather than cosmetic rejuvenation. Treatment depth and coverage are tailored to skin type, location and risk profile.
Precancerous lesions most often develop on chronically sun‑exposed areas. Each area behaves differently in terms of healing, vascularity and cosmetic sensitivity, and treatment parameters are adjusted accordingly.
Laser treatment may be appropriate if you:
It may not be appropriate if:
Laser treatment is delivered within a wider surveillance strategy. This includes documentation, dermoscopy when indicated, follow‑up planning, and clear escalation pathways if lesions recur or change.
This treatment pathway is delivered in a regulated clinical environment with specialist oversight. Consultation is a clinical decision‑making step, not a formality.
Fractional and ablative Er:YAG laser approaches allow predictable epidermal treatment while supporting healing. Settings are chosen conservatively to reduce adverse effects and pigment risk.
Laser is only used when the diagnosis is secure. If histology is required, laser is not appropriate and excision is recommended.
Aftercare includes gentle cleansing, bland occlusive ointment use, sun protection and avoidance of trauma to the treated area. Clear written aftercare instructions are provided.
Laser treatment aims to reduce lesion burden and future risk rather than guarantee permanent clearance. Ongoing prevention and monitoring remain essential.
Consultation is required before treatment. Treatment price depends on the size of the treatment area, lesion burden and number of sessions required. A written plan is provided in advance.
Consultations are doctor‑led. Laser treatment is delivered by an experienced laser therapist within a medically supervised pathway overseen by Dr Bela.
Yes, when diagnosis is secure and selection is appropriate.
Redness, crusting and temporary pigment change are possible. Serious complications are uncommon.
Some patients respond after one session; others may require multiple treatments depending on disease extent.
Laser is one option within a broader treatment landscape and may be combined with other therapies.
No. Laser treats selected precancerous lesions and does not replace surveillance.
Sun protection, skin monitoring and ongoing dermatology review are key.
