Squamous Cell Carcinoma

Squamous Cell Carcinoma (SCC)

Overview

Squamous cell carcinoma is the second most common form of skin cancer, arising from squamous cells in the outer layers of the skin. It is primarily caused by cumulative UV radiation exposure. While most SCCs are treatable when caught early, some can metastasize if left untreated.

Key Symptoms

  • Firm, red, scaly nodule or flat sore with a crusty surface
  • New sore or raised area on existing scar, ulcer, or chronic wound
  • Rough, thickened, or wart-like patch on the skin
  • Open sore that bleeds, crusts, and does not heal
  • Tender or painful lesion that persists
  • May develop rapidly over weeks to months

Affected Areas

Face, Ears, Lips, Scalp, Hands, Arms, Legs
