Pre-cancerous Sun Spots

Solar Keratoses (‘SunSpots’)

Solar keratosis are also known as sunspots or actinic keratosis.

Sunspots are a pre-cancerous lesion, if not treated some will develop into a Squamous cell carcinoma.

Sunspots (or solar keratosis or actinic keratosis) are rough, scaly spots or patches on skin that has been previously exposed to the sun. They can be reddish brown or skin-coloured, often with white a scale or crust. They may be sensitive with a stinging sensation.

If a solar keratosis becomes tender ,thickened or lumpy get it checked; it may have become a squamous cell cancer.

A person may have a single sunspot, but over time, more usually develop.

Treatment options for Solar keratosis

Cryotherapy

Liquid nitrogen is used to freeze and kill the precancerous cells.

The treatment stings at the time, then becomes raised and pink and occasionally blisters.

A scab develops after a few days.

The treated area heals in 7-10 days on the face, 14 days on the arms and 2-4 weeks on the legs.

The area normally heals well, however, there is a small risk of leaving a permanent white mark.

Efudix cream (5 Fluorouracil)

Efudix cream is usually applied twice a day for 3 weeks for facial sun spots.

The cream can be applied to individual sun spots or to large facial areas.

When treating a large areas on the face, Efudix treats not only visible sun spots ,but also microscopic ones which are not yet visible.

Efudix has approximately an 80% cure rate.

Cost is approximately $60 from your chemist. A prescription is required.

During treatment the area will become red, crusted and sometimes uncomfortable.

The final cosmetic result is excellent

Photodynamic Therapy (PDT)
