Squamous Cell Carcinoma is caused by the cumulative effects of ultraviolet light on the DNA in skin cells and so most commonly occur in fair skinned people at sites of highest sun exposure.
Squamous Cell Carcinoma appears as lumps or ulcers that most commonly develop on the scalp, face, ears, backs of the hands and legs and usually bleed, weep or are crusty.
If ignored, squamous cell carcinomas can spread to other parts of the body, such as the local lymph glands. Squamous cell carcinomas arising on the ears and lips are particularly prone to spread.
Surgery remains the gold standard treatment for Squamous Cell Carcinoma. Treatment should be carried out within one month of the diagnosis.
Wearing a sunscreen will help. A sunscreen with SPF 20 and *** to **** UVA protection is ideal. Sunscreens containing mexoryl are amongst the least white available. A hat protects the scalp and forehead only.
