Squamous cell carcinoma
After basal cell carcinoma, squamous cell carcinoma is the second most common variant of skin cancer. It is more prevalent in lighter-skinned patients, especially in areas with frequent sun exposure, including the neck, arms, and the rim of the ear. It might appear in the upper region of the chest, and sometimes in the back. Squamous cell carcinoma is often more noticeable compared to basal cell carcinoma. It looks like a scaly area or patch in the skin, a red bump or a sore that never heals completely, and some cases are more aggressive than others. It is important to start an early treatment in order to prevent the spread of this type of cancer in cases of aggressive variants.
