Squamous Cell Carcinoma

Squamous cell carcinoma (SCC) is one of the most common forms of non-melanoma skin cancer. And while it is highly treatable when caught early on, it can be more aggressive than basal cell carcinoma (BCC) and may spread to the lymph nodes or internal organs when untreated. Early intervention and expert care are crucial.

Montserrat’s team of specialist surgeons are highly experienced in the detection, surgical removal and post-treatment care of squamous cell carcinoma. We use state-of-the-art techniques in our exceptional facilities to make sure removal is successful while protecting the cosmetic look of your skin, with minimal scarring and patient comfort front-of-mind. We work closely with every patient to create a personalised treatment plan, as well as ongoing support to reduce the risk of recurrence.

If you have noticed a persistent lesion, scaly patch or abnormal growth on your skin, contact the team at Montserrat today to book a consultation.

What is Squamous Cell Carcinoma?

Squamous cell carcinoma is a common type of skin cancer that arises from squamous cells, which are found in the upper layers of the epidermis. Unlike basal cell carcinoma, which grows slowly and rarely spreads, these cancer cells have a greater potential to invade deeper tissues and spread into other parts of the body, including the lymph nodes and internal organs.

It’s most commonly found on areas of the body that get regular sun exposure, such as around the face, ears, neck, hands and scalp. But it can still develop in areas not exposed to the sun, including the mucous membranes and genitals.

Like BCC and melanoma, squamous cell carcinoma is classified as a keratinocyte cancer, a term now used to describe non-melanoma skin cancers. The main reason people develop squamous cell carcinoma is due to repeated UV exposure, which is preventable with good sun protection and regular skin checks.

Montserrat delivers specialist-led treatment for SCC, from early-stage lesions to more advanced cases requiring complex surgical intervention to treat squamous cell carcinoma.

Symptoms and Risk Factors

Unlike some skin conditions that can resolve on their own, squamous cell skin cancer tends to persist, grow and change over time. Some of the more common symptoms include:

  • A rough, scaly patch of skin that is unable to heal.
  • A firm, red nodule that bleeds or develops a crust.
  • An open sore that doesn’t heal, or heals and returns.
  • A wart-like growth that is tender or painful to touch.
  • A raised, thickened lesion with an uneven surface.

Bear in mind that while the biggest risk factor for squamous cell carcinoma is sun exposure, other factors can increase the likelihood of developing squamous cell cancers, including:

  • Fair skin and light-coloured eyes, which are more prone to UV damage.
  • A history of sunburns or chronic sun exposure.
  • Using tanning beds, which emit harmful ultraviolet radiation.
  • A weakened immune system (e.g. due to conditions like organ transplants or long-term immunosuppressive medication).
  • A history of previous skin cancer, including basal cell cancer or melanoma.

Types of Squamous Cell Carcinoma

Cutaneous squamous cell carcinoma

The most common type, developing on sun-exposed skin like the face, scalp and hands.

In situ (Bowen’s disease)

An early form that stays confined to the top layer of the skin.

Invasive

A more advanced form that can penetrate into deeper layers of skin and spread to nearby tissues.

Mucosal

A rare form that occurs in the mouth, throat or genitals.

The Differences Between Basal Cell and Squamous Cell Carcinoma

Prevalence: Most common type of skin cancer (~70% of cases)

Growth: Slow-growing, rarely spreads

Appearance: Pearly, waxy lump or scar-like lesion

Located: Face, neck, back and ears

Treatment: Surgical excision

Prevalence: Second most common type (~30% of cases)

Growth: Faster-growing, can spread to lymph nodes

Appearance: Scaly, rough patch or wart-like sore

Located: Sun-exposed areas like scalp, lips and hands

Treatment: Needs surgical removal, potentially including radiation therapy

Diagnosis of
Non-Melanoma Skin Cancer

A clinical skin exam is the first step in diagnosing squamous cell carcinoma. If a lesion looks suspicious, a skin biopsy should be carried out, which will involve removing a small portion of the lesion for further analysis under a microscope.

For more advanced cases, imaging tests (CT scans, MRIs or ultrasounds) are used to see if the cancer has spread to the lymph nodes or other organs. Early diagnosis and treatment are essential to prevent squamous cell carcinoma and improve patient outcomes.

Treatment Options for Diagnosed Squamous Cell Carcinoma

Staging

SCC is usually staged based on the size of the tumour, as well as its depth and potential to spread:

  • Stage 0 (in situ): Cancer is confined to the epidermis.
  • Stage I–II: Cancer has grown into deeper layers of the skin.
  • Stage III–IV: Cancer has spread beyond the skin to lymph nodes or organs.

Surgical Treatment

  • Wide local excision: Removes the tumour and surrounding tissue.
  • Lymph node dissection: Performed if the cancer has spread beyond the skin.

Other Treatments

Further treatments beyond the above include radiation therapy (for high-risk or recurrent cases), topical chemotherapy and immunotherapy, which is generally only for advanced cases where surgery isn’t an option.

Prevention of Skin Cancer

Preventing squamous cell carcinoma and other skin cancer types should start with a proactive approach to sun safety and your overall skin health. Since squamous cell carcinoma is mostly caused by serious UV radiation exposure, minimising sun damage is one of the easiest ways to lower your risk of developing non-melanoma skin cancers.

Make sure you apply a broad-spectrum sunscreen with a high SPF rating, even on cloudy days, to protect your skin from harmful UVA and UVB rays. Also wear protective clothing (i.e. long sleeves, wide-brimmed hats, sunglasses) for an extra layer of defence against the sun’s rays.

Beyond sun protection, it’s a good idea to do regular self-examinations of your skin to spot abnormal lesions. If you notice persistent sores, rough patches or scaly growths that don’t heal over time, this might mean a type of skin cancer is present. Make sure you also get routine skin checks with a doctor so that any suspicious changes are investigated and treated at an early stage.

For those who have a history of skin cancer, you’ll also want to focus on follow-up care to monitor your skin for new issues. A few lifestyle changes like maintaining a healthy immune system, limiting your exposure to environmental toxins and prioritising your overall skin health will help in protecting against skin cancer recurrence for years to come.
