Early Detection of Skin Cancer

Read our Facial basal cell carcinoma publication in the BMJ (free)

I specialise in the early detection of skin cancers such as basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and malignant melanoma (MM) and pre-cancers of the skin such as Bowen’s disease (IEC) and actinic keratoses.

The early detection of skin cancer is crucial to improving outcome – especially for MM and certain SCC. The sooner a MM is picked up and excised the better the chances of long term non-recurrence (“cure”).

The best way to making an early diagnosis is through a thorough history of the problem, and close examination of the lesion.

Dermatoscopy helps a great deal with diagnosis. Using a dermatoscope can take years of experience to look at lesions to decide which are benign, pre-cancerous, suspicious or cancerous lesion.

Below are some examples of early diagnosis of skin lesions.

For example, there are 2 examples below which show small, early, non-descript skin lumps. These could have been overlooked. Dermatoscopically, they show the hallmark features (arborising telangiectasia, blue grey ovoid globule) of basal cell carcinoma. Surgery was performed which confirmed complete excision of BCC.

The next two photos show a lesion which was suspected of being a cancer but which is completely harmless.
