Types of Skin Cancer: Squamous Cell Carcinoma (SCC)

1 min read ·

Squamous cell carcinoma (SCC) is the second most common form of skin cancer. It develops from squamous cells in the upper layers of the epidermis and is also strongly associated with cumulative UV exposure. Although many SCCs are successfully treated, some have the potential to grow more rapidly and spread to nearby lymph nodes or other parts of the body if left untreated.

 

Signs and Symptoms

SCC may appear as:

  • A firm, red nodule
  • A thickened or scaly patch
  • A crusted or ulcerated lesion
  • A sore that does not heal
  • A lesion that becomes painful or tender

SCC frequently occurs on the face, ears, scalp, lips, neck and backs of the hands.

 

Risk Factors

Factors that may increase your risk include:

  • Long-term sun exposure
  • Fair skin
  • Increasing age
  • Weakened immune system
  • Previous skin cancer
  • Chronic wounds or inflamed skin
  • Exposure to certain environmental carcinogens

 

Diagnosis

Diagnosis is usually confirmed through clinical examination and biopsy. Your doctor may recommend additional investigations if there are features suggesting a higher-risk tumour.

 

Treatment Options

Treatment is determined by the tumour’s size, location and risk profile. Options may include:

  • Surgical excision
  • Mohs micrographic surgery
  • Radiation therapy
  • Cryotherapy (exceptional cases)
  • Systemic therapies for advanced disease
  • Rhenium-SCT for selected superficial lesions where clinically appropriate

 

Early treatment provides the best opportunity for successful disease control.
