SCC

Squamous cell carcinoma (SCC) is a type of skin cancer that arises from the squamous cells in the outer layer of the skin, known as the epidermis. It commonly develops in areas frequently exposed to the sun, such as the face, ears, neck, and backs of the hands, but can also occur in other areas of the body. SCC often presents as a persistent, scaly patch, an open sore that doesn’t heal, or a growth that may bleed or crust over. Unlike basal cell carcinoma, SCC has a higher likelihood of metastasizing to nearby tissues or lymph nodes if left untreated, making early diagnosis and treatment crucial.

The primary risk factor for SCC is chronic ultraviolet (UV) radiation exposure from the sun or artificial sources like tanning beds, which damages the skin’s DNA and triggers cancerous changes in the squamous cells. Other contributing factors include a history of sunburns, fair skin, a weakened immune system, and certain genetic conditions. Treatment for SCC typically involves surgical removal of the tumor, and may also include cryotherapy, topical chemotherapy, or radiation therapy depending on the tumor’s size, location, and stage. With appropriate treatment, the prognosis for SCC is generally favorable, but regular skin checks and effective sun protection are essential to reduce the risk of developing this cancer and to catch it early if it does occur.
