Basal Cell Carcinoma
Basal cell cancer, sometimes called non-melanoma
skin cancer , usually appears as a small, fleshy bump or nodule on
the head, neck, or hands.
In the United States, basal cell cancer accounts for 90 percent
of all skin cancers in the southern states,
and 47 percent in the northern states. Fair skinned people
over age 50 are most commonly affected it is rare among those with
dark skin. Risk is increased for individuals with a family history
of the disease
and a high cumulative exposure to UV light via sunlight or,
in the past, carcinogenic chemicals especially arsenic .
Treatment is with surgery , topical chemotherapy , x-ray,
cryosurgery, photodynamic therapy. It is rarely life-threatening but
if left untreated can be disfiguring, cause bleeding
and produce local destruction (eg., eye, ear, nose, lip).
