Visual Guide to Squamous Cell Carcinoma

Recognizing Squamous Cell Carcinoma Symptoms

Excessive sun exposure poses serious risks to your skin beyond just tanning. Prolonged sunbathing can significantly increase your chances of developing skin cancer.

Squamous cell carcinoma (SCC) is a prevalent form of skin cancer that primarily appears on sun-exposed regions such as the arms, legs, face, hands, neck, and lips. It can also manifest inside the mouth or on genital areas.

Understanding Bowen’s Disease

Bowen’s disease, also known as squamous cell carcinoma in situ, represents the earliest stage of SCC. This precancerous lesion typically looks like a flat, reddish, scaly patch on the skin, often exceeding one inch in size and growing slowly over time.

Approximately 5% of Bowen’s disease cases progress into invasive squamous cell carcinoma. It is most commonly diagnosed in older Caucasian men.

What is Actinic Keratosis?

Actinic keratosis (AK) consists of precancerous skin growths frequently mistaken for sunspots or age spots. These lesions can eventually develop into squamous cell carcinoma.

They may cause itching, burning sensations, or pain when touched. In some instances, actinic keratosis leads to dry, flaky lips.

Identifying Suspicious Bumps or Lumps

Newly formed skin bumps should not be dismissed as harmless moles or cysts. SCC often begins as a firm, raised bump that becomes dome-shaped and may ulcerate, bleed, and form a crust. Some lesions grow rapidly.

Cancerous skin growths tend to develop quicker than those caused by other conditions and can appear on previously scarred skin.

Non-Healing Sores: A Warning Sign

While pimples and minor sores are common and usually heal within days, a sore that persists without healing might indicate a serious condition.

Squamous cell carcinoma can hinder the skin’s natural healing process. Persistent sores that bleed easily when irritated should be evaluated by a healthcare professional.

Monitoring Changes in Existing Skin Lesions

Most warts and moles are harmless, but since SCC can arise from existing skin lesions, it’s vital to watch for any changes in size, shape, or color. Any noticeable alteration warrants prompt medical assessment.

Prognosis and Early Detection

The outlook for SCC depends on factors such as:

• The stage of cancer at diagnosis
• The tumor’s location on the body
• Whether the cancer has metastasized

Early diagnosis improves treatment success and increases the chances of a cure. Addressing precancerous conditions like Bowen’s disease or actinic keratosis early is crucial. Consult your doctor immediately if you notice any unusual or new skin changes.

Regular skin examinations by a healthcare provider and monthly self-checks are essential. Use mirrors or enlist help to inspect areas that are hard to see, including your back and scalp.

Individuals with fair skin, light hair, and light eyes, as well as those frequently exposed to sunlight without protection, are at greater risk.

Preventing Recurrence

After a diagnosis of squamous cell carcinoma, the likelihood of recurrence increases even after successful treatment. To minimize this risk, consistently protect your skin from sun exposure.

Limit direct sunlight and apply broad-spectrum sunscreens with an SPF of 30 or higher. Remember that even brief sun exposure can cause damage, so apply sunscreen before any time spent outdoors.

Wearing sun-protective clothing such as long sleeves and pants further reduces UV exposure and helps prevent future skin cancers.
