Squamous Cell Carcinoma (SCC)
Squamous Cell Carcinoma (SCC) is one of the most common types of skin cancer in Australia. It develops in the squamous cells of the skin, which are found in the outer layer (epidermis). This type of skin cancer is usually caused by long-term exposure to ultraviolet (UV) radiation from the sun or tanning beds. While SCC can often be successfully treated when detected early, it has the potential to spread if left untreated. Regular skin checks and sun protection are essential in reducing the risk of developing SCC.
At Karratha Medical Centre, Dr Amir Waly provides expert assessment and management of SCC, offering treatment options tailored to individual needs. Early detection plays a critical role in achieving the best possible outcomes, and any new or changing skin lesions should be professionally evaluated.
Understanding Squamous Cell Carcinoma
SCC often appears as a scaly, red, or thickened patch of skin that may be tender, crusty, or prone to bleeding. It commonly develops on sun-exposed areas such as the face, ears, neck, scalp, arms, and hands. In some cases, SCC may also grow on areas not frequently exposed to the sun, especially in individuals with weakened immune systems.
The primary risk factor for SCC is cumulative sun exposure over time. Individuals with fair skin, outdoor workers, and those with a history of sunburns or previous skin cancers are at higher risk. Other contributing factors include smoking, exposure to harmful chemicals, chronic wounds, and conditions that suppress the immune system.
Treatment Options for Squamous Cell Carcinoma
Treatment for SCC depends on factors such as the size, depth, and location of the lesion, as well as the patient’s overall health. The main goal of treatment is to remove the cancerous tissue while preserving as much healthy skin as possible.
Surgical excision is a common and effective method for removing SCC. The procedure involves carefully excising the cancer along with a small margin of surrounding healthy skin to ensure complete removal. The excised tissue is then sent to a pathology laboratory for confirmation of clear margins. This approach is highly effective in preventing recurrence.
Cryotherapy, or freezing the lesion with liquid nitrogen, may be an option for very small or superficial SCCs. This method destroys the abnormal cells by freezing them, causing the lesion to fall off over time. It is generally reserved for early-stage SCCs.
Curettage and electrodessication involve scraping away the cancerous tissue using a special instrument, followed by cauterisation to eliminate any remaining abnormal cells. This treatment is often used for small SCCs on low-risk areas of the body.
Mohs micrographic surgery is a specialised technique used for SCCs located on cosmetically or functionally sensitive areas such as the face, ears, or hands. This procedure involves removing the cancer layer by layer while preserving as much healthy tissue as possible. Each layer is examined under a microscope to ensure complete removal before proceeding.
Radiation therapy may be considered for individuals who are not suitable candidates for surgery or for cases where the SCC is in a difficult-to-treat location. This treatment uses targeted radiation to destroy cancer cells while minimising damage to surrounding tissue.
Topical treatments, including prescription creams, may be an option for very early-stage SCCs or pre-cancerous lesions known as actinic keratoses. These treatments work by stimulating the immune system to attack abnormal skin cells or by directly destroying cancerous cells.
Frequently Asked Questions
What are the warning signs of Squamous Cell Carcinoma?
SCC often appears as a scaly, crusty, or rough patch of skin that may be red, tender, or prone to bleeding. Any new or changing skin lesion should be checked by a doctor to rule out skin cancer.
Is Squamous Cell Carcinoma serious?
While SCC is usually treatable when detected early, it can spread to deeper tissues and other parts of the body if left untreated. Early diagnosis and treatment significantly improve outcomes.
How is SCC different from other types of skin cancer?
SCC arises from squamous cells in the epidermis and tends to grow more aggressively than basal cell carcinoma (BCC). Unlike melanoma, SCC is less likely to spread to other organs but still requires prompt treatment.
What happens if Squamous Cell Carcinoma is not treated?
If left untreated, SCC can grow larger, invade deeper tissues, and in some cases, spread to lymph nodes or other organs. Early treatment helps prevent complications.
How can I reduce my risk of developing SCC?
Sun protection is the best way to reduce the risk of SCC. Wearing protective clothing, applying sunscreen, avoiding tanning beds, and having regular skin checks can help detect and prevent skin cancer.
