Squamous Cell Carcinoma – Type of skin cancer

Squamous cell carcinoma (SCC) is the second most common form of skin cancer and accounts for 20% of cutaneous malignancies.Squamous cell carcinoma frequently arises on the sun-exposed skin of middle-aged and elderly individuals.

– Squamous cell carcinoma arises from squamous cells in the uppermost layer of epidermis – stratum corneum.
– It appears as a scaly, reddish, dome-shaped, fleshy nodule, from 5 mm to few cm (if left untreated) in size, often with a central ulcer. It mostly appears on sun exposed areas of the skin or lips.
– It grows slowly, but it can spread to other organs.

Squamous Cell Carcinoma

Risks for squamous cell skin cancer include:
– Having light-colored skin, blue or green eyes, or blond or red hair.
– Long-term, daily sun exposure (such as in people who work outside).
– Many severe sunburns early in life.
– Older age.
– A large number of x-rays.
– Arsenic.
– Chemical exposure.
– Chronic skin ulcers.
– Actinic keratoses (These lesions have the potential to progress to squamous cell carcinoma.).
At first cancer cells tend to spread only as far as the nearest lymph nodes clusters of tissue found in the underarms, groin, neck, and other parts of the body that help fight disease. When cancer spreads, they often trap cancer cells. structures, which filter out and trap the cancer cells. If spread has occurred, the affected lymph nodes can be removed before cancer spreads to vital organs.
With early detection and proper treatment, SCC is curable. Allowed to progress, SCC can invade and destroy much of the tissue surrounding the cancerous tumor, which can be disfiguring.
Some SCCs, such as those that develop on a lip or an ear, can be particularly aggressive. Left untreated, aggressive SCCs have a greater risk for metastasis (spreading) to the lymph nodes and other internal organs. This makes early diagnosis and treatment of SCC essential.
