Squamous Cell Carcinoma
Urgent
Squamous cell carcinoma is a type of cancer that develops from squamous cells, which form part of the outer and inner lining of many parts of the body. Cutaneous squamous cell carcinoma commonly develops on areas of skin exposed to sunlight. It may appear as a persistent scaly patch, sore, growth, or area of abnormal skin.

When to Seek Medical Attention
Squamous cell carcinoma requires prompt medical evaluation for a persistent or changing skin lesion, especially a rough or scaly growth, sore that does not heal, bleeding lesion, or rapidly enlarging area. Early treatment is important because some squamous cell carcinomas can grow deeper or spread. Emergency care is generally not required unless there is severe bleeding, infection, or another acute complication.

Overview
Squamous cell carcinoma is a type of cancer that develops from squamous cells, which form part of the outer and inner lining of many parts of the body. Cutaneous squamous cell carcinoma commonly develops on areas of skin exposed to sunlight. It may appear as a persistent scaly patch, sore, growth, or area of abnormal skin.
Symptoms 2
Persistent Hoarseness
Sleep Paralysis
Causes 1
Squamous cell carcinoma of the skin develops when squamous cells undergo abnormal genetic changes and begin multiplying uncontrollably. Ultraviolet radiation from sunlight or tanning devices is a major contributing factor. Other factors include previous radiation treatment, chronic wounds or scars, certain chemical exposures, weakened immune function, and some infections or inherited conditions.
Genetics
Risk Factors
Risk factors include substantial lifetime exposure to ultraviolet radiation, fair or easily sunburned skin, previous skin cancer, treatment with radiation, long-term immune suppression, chronic wounds or scars, and certain inherited conditions. Older age is also associated with increased risk.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Squamous cell carcinoma is usually diagnosed by examining a suspicious skin lesion and performing a skin biopsy. During a biopsy, part or all of the abnormal area may be removed and examined under a microscope. The healthcare professional may also examine nearby lymph nodes or order additional tests when there is concern that the cancer has spread or is high risk.
Prevention
Key Prevention Tips
Reducing ultraviolet exposure can lower the risk of cutaneous squamous cell carcinoma
Protective measures include seeking shade, wearing protective clothing, using broad-spectrum sunscreen, and avoiding indoor tanning
People with previous skin cancer or other high-risk conditions should follow recommended skin examinations and report persistent or changing skin lesions promptly
Prevention Guidance
Reducing ultraviolet exposure can lower the risk of cutaneous squamous cell carcinoma. Protective measures include seeking shade, wearing protective clothing, using broad-spectrum sunscreen, and avoiding indoor tanning. People with previous skin cancer or other high-risk conditions should follow recommended skin examinations and report persistent or changing skin lesions promptly.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
