Squamous cell cancer is a malignant growth of the epithelial layer (external surface) of the skin. Like other skin cancers, it predominantly affects areas of the skin that have been chronically exposed to sunlight. Unlike basal cell cancer, squamous cell cancer can spread, or metastasize to lymph nodes or other organs. These tumors are not painful, unless and ulcer forms that becomes inflamed or infected. These cancers usually occur after 50 years of age.
Causes of Skin Cancer, Squamous Cell
Squamous cell cancer develops in areas of skin that have been exposed to chronic sunlight. Genetic predisposition and fair-skinned complexion are contributing causes.
Signs and Symptoms of Skin Cancer, Squamous Cell
Squamous cell cancer usually produces a small, red, scaling, raised bump or nodule on the skin. It may form a crust on it and frequently ulcerates. The ulcer does not entirely heal. The bump doesn’t hurt or itch. If the cancer has spread, you may feel firm, painless lumps in the lymph nodes adjacent to the tumor (such as the neck, groin or armpit).
