Much less common than Basal Cell Carcinoma (BCC), but occurring in the same sort of age group, Squamous Cell Carcinoma (SCC) tends to grow much more quickly (just weeks or a few months rather than several months to a year or more), going on to ulcerate and bleed much sooner.
Unlike BCC, SCC may also spread elsewhere via the blood stream or by a drainage network of clear fluid known as the lymphatic system.

The diagnosis is confirmed by a tissue biopsy under local anaesthesia and treatment may be by radiotherapy or by surgical removal and repair, often with skin grafts or local flaps (See Surgical Repair section)

Scans may be carried out to exclude or to identify spread.  When spread is present, further treatment is given according to the exact situation and this may involve further surgery.
