Diseases & Conditions: Basal
Cell Carcinoma
Overview
 Basal
cell carcinoma is a type of skin cancer that occurs most
commonly on the face or neck, often near an eyelid or on
the nose. The tumor cells are thought to originate from
the basal, or innermost, layer of the skin.
Basal cell carcinoma is the most common type of skin cancer
in the United States. Fair-skinned people over age 50 are
most commonly affected; it is rare among those with dark
skin. The incidence increases significantly with sun exposure.
Those who work outdoors or live in sunny climates or areas
with high sun exposure are at greater risk.
The ultraviolet radiation in sunlight is believed to be
the cause in most cases. People with dark complexions have
more melanin in their skin and are able to absorb higher
amounts of the damaging ultraviolet rays. Since those with
fair skin have less melanin, they are less able to withstand
the effects of UV exposure.
Signs & Symptoms
- Typically appears on the eyelid (the lower lid is more
common than the upper)
- Begins as a small, raised growth
- Classic appearance is a nodule with a pitted center
- Tumor edges may have a "pearly" appearance
- Does not cause discomfort, but if advanced, may cause
lid to turn in or out
Detection & Diagnosis
If left untreated, the growth may gradually invade the
surrounding tissue. Fortunately, basal cell carcinomas
rarely metastasize (spread to other parts of the body).
Diagnosis is made by microscopic examination of the tumor
cells.
Treatment
Basal cell can be removed surgically or with radiation.
As with any type of cancer, early detection is important.
Consult with an ophthalmologist or dermatologist about
any suspicious growth appearing on the eyelids or skin.
Prevention
Individuals at risk, especially the fair-skinned, should
avoid overexposure to sunlight. Wear sunglasses to protect
the delicate skin around the eyelids from UV light. Protective
clothing, headgear, and sunscreen are also advisable when
spending time outdoors. Read Our Disclaimer |
